Can Cats Eat Liver Safely?
Yes, cats can eat liver, but with important caveats. Liver is a nutrient-dense organ meat that forms a part of many commercial cat foods, and it can be a beneficial addition to a cat's diet when prepared and offered correctly. However, overfeeding or improperly prepared liver can lead to health issues, making it vital to understand the nuances of feline nutrition before incorporating it.
- Liver offers essential nutrients like Vitamin A and iron for cats.
- Too much liver can cause Vitamin A toxicity.
- Cooked, unseasoned liver is safest for feline consumption.
- Raw liver carries a risk of bacterial contamination.
- Portion control is paramount when feeding liver to cats.
Cats are obligate carnivores, meaning their diet primarily consists of meat. Liver, being an organ meat, is rich in vitamins, minerals, and protein that are vital for feline health. It's a concentrated source of nutrients like Vitamin A, Vitamin D, B vitamins, iron, copper, and zinc. These elements support vision, immune function, bone health, and energy metabolism. For instance, Vitamin A is critical for maintaining healthy eyesight, while iron is essential for carrying oxygen in the blood. B vitamins play a crucial role in energy production and nerve function. In essence, liver can be a highly beneficial component of a cat's diet, provided it is administered wisely.
However, the very concentration of these nutrients is also where the danger lies. Liver is particularly high in Vitamin A. While cats need Vitamin A, they cannot efficiently convert beta-carotene (found in plants) into Vitamin A as humans can. They must obtain it directly from animal sources, making liver a potent source. If a cat consumes too much Vitamin A, it can lead to a condition called hypervitaminosis A, or Vitamin A toxicity. This condition can cause severe health problems, including bone deformities, joint pain, lethargy, and even death in extreme cases.
This duality – its nutritional value versus its potential for toxicity – means that responsible feeding is not just recommended; it's essential. The goal is to leverage the benefits without succumbing to the risks. This requires careful consideration of the type of liver, its preparation, the frequency of feeding, and, most importantly, the portion size relative to the cat's overall diet.
Nutritional Profile of Liver
Liver's appeal to cats stems from its rich nutritional makeup. As a powerhouse of essential vitamins and minerals, it can supplement a cat's diet effectively. Key nutrients found in liver include:
- Vitamin A: Crucial for vision, immune system function, and cell growth. Cats rely on preformed Vitamin A from animal sources.
- B Vitamins (B1, B2, B3, B5, B6, B9, B12): These are vital for energy metabolism, nerve function, and red blood cell formation.
- Iron: Essential for oxygen transport in the blood and preventing anaemia.
- Copper: Aids in iron absorption and enzyme function.
- Zinc: Supports immune health and wound healing.
- Protein: Liver is a good source of high-quality animal protein, which cats require for muscle development and overall bodily function.
When considering how much dry food to feed a cat, it's important to remember that a balanced diet is key. Liver, as a supplement, should not replace a cat's primary, balanced cat food. Instead, it should be seen as an occasional treat or a small addition to their regular meals. The high concentration of nutrients means even small amounts can have a significant impact.
Potential Risks of Feeding Liver to Cats
While liver is packed with nutrients, feeding it to cats isn't without its risks. The primary concern is the high concentration of Vitamin A, which can lead to hypervitaminosis A if consumed in excessive amounts over time. This condition can manifest as painful bone spurs, particularly around the neck and spine, leading to stiffness, reduced mobility, and reluctance to move. Cats may also experience lethargy, loss of appetite, and weight loss. In severe, chronic cases, it can be irreversible and life-threatening.
Another significant risk, especially with raw liver, is the potential for bacterial contamination. Raw meat can harbour pathogens such as Salmonella, E. coli, and Listeria. While cats have more robust digestive systems than humans, they are not immune to these bacteria. Ingesting contaminated raw liver can cause gastrointestinal upset, including vomiting and diarrhoea. More worryingly, these pathogens can also pose a risk to humans in the household, particularly young children, the elderly, or immunocompromised individuals, through cross-contamination during preparation or handling.
Beyond Vitamin A toxicity and bacterial risks, improperly prepared liver can also be problematic. Feeding liver seasoned with onion or garlic, for example, is toxic to cats and should be avoided entirely. Even small amounts of these common human food ingredients can cause damage to a cat's red blood cells, leading to anaemia. Similarly, feeding liver cooked with excessive salt or other spices can be detrimental to a cat's health, potentially contributing to dehydration or other health issues.
The texture and consistency of liver can also present a choking hazard for some cats, particularly if fed in large, irregular chunks. While cats are adept at consuming meat, presenting large pieces of liver might be more challenging for them to manage safely.
Finally, consider the source of the liver. If you're feeding human-grade liver, ensure it's from a reputable source that adheres to safety standards. If you're considering feeding liver from prey, such as do cats eat rats, it's crucial to understand the health of the prey animal, as liver can store toxins if the animal has been exposed to poisons.
Always introduce any new food, including liver, gradually and in very small amounts to monitor your cat for any adverse reactions.
Vitamin A Toxicity Explained
Vitamin A is a fat-soluble vitamin, meaning the body stores any excess rather than excreting it. This property makes it both beneficial and potentially dangerous. For cats, liver is a primary dietary source of Vitamin A. A healthy intake supports their vision, skin, coat, and immune system. However, the toxicity threshold for Vitamin A in cats is not exceptionally high. Consistently feeding liver as a staple food, or in overly generous portions, can quickly lead to an accumulation in the body, resulting in hypervitaminosis A. Symptoms might not appear immediately, developing over weeks or months of excessive intake. The effects can be severe, impacting bone structure and joint health, which is why moderation is key.
Bacterial Contamination Concerns
The risk of bacterial contamination in raw liver cannot be overstated. Pathogens like Salmonella can cause severe gastrointestinal distress in cats. While some cats might tolerate small amounts of raw meat without ill effect, others can become seriously ill. Furthermore, handling raw liver poses a risk to human health. If you choose to feed raw liver, rigorous hygiene practices are non-negotiable. This includes thorough handwashing after handling the meat, sanitising preparation surfaces, and ensuring no raw meat juices come into contact with other foods or surfaces that humans will use. For most owners, the safest approach is to avoid raw liver altogether.
Toxic Ingredients to Avoid
Many common human foods are toxic to cats, and liver is no exception when prepared with certain ingredients. Onions, garlic, chives, and leeks (all members of the Allium family) are highly toxic to cats. They contain compounds that can damage a cat's red blood cells, leading to anaemia. Symptoms of poisoning can include lethargy, weakness, pale gums, and rapid breathing. Always ensure that any liver fed to your cat is plain and unseasoned. If you're wondering what human food can kittens eat or what human food cats can eat generally, it’s crucial to research each item individually to ensure it’s safe.
How to Safely Prepare and Serve Liver
When it comes to feeding liver to your cat, safety and moderation are paramount. The safest and most recommended method is to cook the liver thoroughly. This process neutralises potential bacterial contaminants and makes the nutrients more digestible for your feline friend. Avoid frying the liver, as this often involves added fats and oils that are not ideal for a cat's digestive system. Baking, boiling, or steaming are the preferred methods.
Always ensure the liver is cooked until it is no longer pink inside. It should be firm to the touch. Once cooked, allow it to cool completely before serving. The liver should then be cut into small, manageable pieces. Think of bite-sized cubes, no larger than your cat's kibble or a small pea. This prevents choking hazards and makes it easier for your cat to consume.
The amount of liver you offer should be very small. As a general guideline, liver should not constitute more than 5-10% of your cat's total daily caloric intake. For an average adult cat, this translates to roughly a teaspoon or two of cooked liver a few times a week at most. It's best used as an occasional treat rather than a daily food source. If your cat has any underlying health conditions, such as kidney or liver disease, consult your veterinarian before introducing liver into their diet.
When introducing liver, start with a tiny amount – even less than a teaspoon – to see how your cat reacts. Some cats might not like the taste or texture, while others might experience digestive upset. If your cat tolerates it well, you can gradually increase the portion size up to the recommended limit, but never exceed it.
It's also worth noting that some cats might react differently to various types of liver. Beef liver is commonly available and is a good choice. Chicken or turkey liver are also options, though they are generally smaller and might be easier to overfeed by volume. The key is consistency in portion control regardless of the source.
Feeding liver to your cat is about balancing its rich nutritional benefits against the risks of overconsumption and improper preparation.
Cooking Methods for Cat Liver
Several cooking methods are suitable for preparing liver for your cat. The aim is to cook it safely without adding any harmful ingredients. Boiling or steaming are excellent choices because they are simple and do not require added fats. Simply place the liver in water or a steamer basket and cook until no pink remains in the centre. Baking is another viable option; place the liver on a baking sheet and bake at a moderate temperature (around 180°C or 350°F) until thoroughly cooked.
Important: Never season the liver with salt, pepper, garlic, onion powder, or any other spices or flavourings. These can be harmful to your cat. The liver should be served plain.
Portion Control is Key
Determining the correct portion size is perhaps the most critical aspect of feeding liver to your cat. As a general rule, liver should be treated as a treat or a supplement, not a meal replacement. A common recommendation is that liver should not make up more than 5-10% of your cat's total daily food intake. For an average 4kg cat consuming approximately 200-250 calories per day, this means no more than 10-25 calories from liver, which equates to about one or two teaspoons of cooked liver, offered only a few times per week.
Introducing New Foods
When you first offer liver to your cat, start with a very small piece, perhaps the size of a small pea. Observe your cat for any signs of digestive upset, such as vomiting or diarrhoea, over the next 24-48 hours. If your cat tolerates it well, you can slowly increase the amount over subsequent feedings, always staying within the recommended portion guidelines. If your cat shows any signs of intolerance, discontinue feeding liver and consult your veterinarian.
Liver as Part of a Balanced Cat Diet
While liver offers a concentrated source of valuable nutrients, it should never be the sole component of a cat's diet. Cats are obligate carnivores with specific dietary requirements that are best met by a commercially formulated, balanced cat food. These foods are designed to provide the correct ratio of proteins, fats, carbohydrates, vitamins, and minerals necessary for a cat's long-term health. Liver, when fed appropriately, can act as a beneficial supplement to this balanced diet, but it cannot replace it.
Think of liver as a highly nutritious 'treat' or a small addition to their regular meals. It can be particularly useful for cats that are picky eaters, as the strong aroma and flavour of liver might entice them. It can also be a good option for enriching homemade diets, provided the homemade diet is formulated by a veterinary nutritionist to ensure it's complete and balanced. However, if you are feeding a high-quality commercial cat food, adding liver might be unnecessary and could even disrupt the carefully balanced nutrient profile of their main food if not managed carefully.
The goal is always to provide a diet that is complete and balanced. This means ensuring your cat receives all the necessary nutrients in the correct proportions. A diet too high in Vitamin A from liver can cause toxicity, while a diet deficient in other essential nutrients (because liver is replacing balanced food) can lead to malnutrition. It's a fine line, and understanding your cat's overall nutritional needs is key.
If you are considering incorporating liver into your cat's diet, especially if you are moving away from commercial food, it is highly advisable to consult with your veterinarian or a certified veterinary nutritionist. They can help you understand your cat's specific caloric and nutritional requirements and advise on the safest and most effective way to include liver, if at all. This professional guidance is invaluable for preventing nutritional imbalances and health issues.
For instance, if you're wondering how much dry food to feed a cat, and you're considering adding liver, you must account for the calories and nutrients from the liver within the total daily allowance. This prevents overfeeding and potential weight gain, as well as nutritional imbalance. Similarly, if you're exploring what human food can kittens eat, remember that kittens have even more specific and sensitive nutritional needs, and introducing organ meats like liver should be done with extreme caution and professional advice.
Always calculate the caloric contribution of any treats, including liver, and adjust their main meal accordingly to maintain a healthy weight and balanced diet.
The Role of Liver in Homemade Diets
When formulating a homemade diet for a cat, liver often plays a role as a source of essential vitamins and minerals that can be difficult to balance otherwise. However, it's crucial that the recipe is precisely calculated. A common ratio in raw or cooked homemade diets might involve 5-10% liver as part of the total meat content. For example, in a diet comprising 80% muscle meat, 10% organ meat (including liver), and 10% bone, the liver component would be a small fraction of the overall food. Without expert formulation, this balance can easily be skewed, leading to either toxicity or deficiency. For cats, raw liver is sometimes used in homemade diets, but the associated bacterial risks remain.
Commercial Cat Food vs. Liver Supplements
Commercial cat foods are formulated by animal nutritionists to meet established dietary standards, such as those set by the AAFCO (Association of American Feed Control Officials). They provide a complete and balanced nutrition profile. Liver is often included as an ingredient in these foods in controlled amounts, contributing to the overall nutrient content. Adding extra liver as a supplement to a cat already eating a balanced commercial diet increases the risk of overconsumption and toxicity. It's generally best to rely on the quality of your chosen cat food and use liver only as an occasional, small treat if desired, rather than as a dietary staple or primary supplement.
When to Consult a Veterinarian
It is always wise to consult your veterinarian before making significant changes to your cat's diet, especially when introducing new foods like liver or considering homemade diets. Your vet can assess your cat's individual health needs, including age, activity level, and any pre-existing conditions. They can advise on the appropriateness of feeding liver, the correct quantities, and frequency, and help you understand potential interactions with medications or existing health issues. For example, if your cat has kidney issues, the high protein and mineral content of liver might need careful consideration.
Alternatives to Liver for Cat Nutrition
While liver is a nutritional powerhouse, it’s not the only way to ensure your cat receives a broad spectrum of essential vitamins and minerals. If you're concerned about the risks associated with feeding liver, or if your cat simply doesn't take to it, there are several excellent alternatives. The most straightforward approach is to ensure your cat is fed a high-quality, commercially prepared cat food that is certified as 'complete and balanced' for their life stage. These foods contain all the necessary nutrients in the correct ratios, without the risks of over-supplementation.
For owners looking to supplement their cat's diet with other organ meats, consider other nutrient-rich options like heart. Heart meat is a good source of protein, iron, and B vitamins, and it doesn't carry the same Vitamin A toxicity risk as liver. It's also a favourite texture for many cats. Kidney is another organ meat, rich in Vitamin A and B vitamins, but it should also be fed in moderation due to its Vitamin A content, though typically less concentrated than liver.
If you are interested in providing novel protein sources or different textures, consider lean muscle meats like chicken, turkey, or beef. These are excellent sources of protein and various micronutrients. Fish can also be a part of a cat's diet, but it should be fed cautiously. Oily fish like salmon or mackerel, when cooked and fed in moderation, can provide omega-3 fatty acids beneficial for skin and coat health. However, some fish contain thiaminase, an enzyme that destroys thiamine (a B vitamin), and feeding too much raw fish can lead to thiamine deficiency. Also, be wary of bones in fish. While fish swimming for cats is an image of nature, feeding raw fish to domestic cats requires careful consideration of safety and nutritional balance.
For owners exploring plant-based foods, it's important to remember that cats are obligate carnivores. While they can tolerate small amounts of certain plant-based ingredients, they do not derive essential nutrients from them in the same way omnivores or herbivores do. For example, can cats eat cashews or can cats eat kiwi? In very small, plain, cooked amounts, they might not cause harm, but they offer little to no nutritional benefit and could potentially cause digestive upset. Similarly, can cats eat peppers? Most cats have no interest in them, and they offer little nutritional value. Can cats eat pancakes? A tiny bit of plain pancake might be tolerated, but it's primarily carbohydrates and not suitable for regular feeding.
The key takeaway is that while cats can technically consume a wide variety of foods, their specific needs as obligate carnivores mean that meat-based proteins and nutrients are paramount. If you're looking to supplement, sticking to other animal-based products like muscle meat or heart, or ensuring you're using a high-quality commercial food, is generally the safest and most effective approach.
Prioritise commercially balanced cat food as the foundation of your cat's diet, and view any additional foods as optional, small supplements.
Other Organ Meats
Besides liver, other organ meats can be part of a cat's diet. Heart, for instance, is an excellent source of taurine, an essential amino acid for cats that supports heart health and vision. It's also rich in protein and iron. Kidney is another organ meat that is nutritious, providing iron, B vitamins, and Vitamin A, but like liver, it should be fed in moderation due to its nutrient density and Vitamin A content. When feeding these, preparation is similar: cook them plain and cut into small, manageable pieces. Ensure they are sourced from healthy animals and are safe for feline consumption.
Muscle Meats and Fish
Lean muscle meats such as chicken breast, turkey thigh, or lean beef are excellent protein sources and are generally well-tolerated by cats. They provide essential amino acids and are a good base for homemade diets. Fish, such as salmon or tuna (in moderation and cooked), can offer omega-3 fatty acids. However, it's crucial to avoid feeding fish daily, as it can lead to mercury poisoning or thiamine deficiency if not handled correctly. It's also important to only feed cooked fish, especially if it's from a human food source, to mitigate parasite risks. Ensure any fish is boneless and unseasoned. While many people wonder if cats eat rats in the wild, it's not advisable to feed your pet cat wild-caught prey due to potential parasites and toxins.
Understanding Cat Nutritional Needs
Cats require a diet high in animal protein, moderate in fat, and very low in carbohydrates. They have specific requirements for amino acids like taurine, and fatty acids like arachidonic acid, which they cannot synthesise themselves. They also need specific vitamins and minerals in precise amounts. Commercial cat foods are formulated to meet these specific requirements. If you are considering supplementing with foods like liver, or exploring other options like can cats eat salami (which is high in fat and salt, making it unsuitable), it's vital to understand how these foods fit into your cat's overall nutritional picture. Consulting a veterinarian is the best way to ensure your cat's diet is complete and balanced, preventing potential deficiencies or toxicities that could arise from feeding inappropriate foods or incorrect quantities.
Common Mistakes to Avoid When Feeding Liver
When venturing into feeding your cat liver, it's easy to make mistakes that could inadvertently harm your pet. Being aware of these common pitfalls can help you provide this nutrient-rich food safely. One of the most frequent errors is overfeeding. Liver is not a food to be given freely; its potency means even small excesses can cause problems. Owners might offer too large a portion, or feed it too frequently, leading to Vitamin A toxicity over time. Remember, liver should be an occasional treat, making up a tiny fraction of their total diet.
Another significant mistake is feeding raw liver without proper precautions. While some proponents of raw feeding advocate for it, the risk of bacterial contamination leading to illness in both cats and humans is substantial. Cooked liver, prepared safely, is a far more reliable option for most pet owners. Furthermore, using liver that has been seasoned or cooked with human-friendly ingredients like garlic, onion, or excessive salt is a critical error. These common flavour enhancers are toxic or harmful to cats and must be avoided entirely.
Serving liver in large, unmanageable chunks is also a mistake that can lead to choking hazards. Cats, especially if they are enthusiastic eaters, may try to swallow large pieces whole. Always cut the cooked liver into small, bite-sized pieces appropriate for your cat's size and chewing ability. Lastly, failing to consider the liver's nutritional contribution to the cat's overall diet is a common oversight. If you give your cat liver, you must account for its calories and nutrients, potentially reducing their main meal slightly to maintain a balanced intake and prevent weight gain.
It is also crucial to avoid feeding liver from unknown or unreliable sources. If the liver is not human-grade or from a reputable butcher, it may have been exposed to contaminants or medications that could be harmful to your cat. Always source your ingredients responsibly.
Overfeeding and Frequency
The most common mistake is simply giving too much liver, too often. Liver is highly concentrated in Vitamin A. While cats need Vitamin A, they cannot process excessive amounts efficiently, leading to hypervitaminosis A. A general guideline is that liver should account for no more than 5-10% of a cat's total daily caloric intake, and it should only be offered a few times per week at most, not as a daily food. For context, a tiny piece, about the size of a thumbnail, is often sufficient for a single treat.
Using Seasoned or Raw Liver
Feeding raw liver carries a risk of bacterial contamination (Salmonella, E. coli) for both pets and humans. It's safer to cook liver thoroughly. Additionally, never feed liver seasoned with human spices, particularly onion, garlic, or excessive salt. These ingredients are toxic to cats and can cause serious health problems, including anaemia from onion and garlic. Always serve liver plain and unseasoned.
Incorrect Portion Size and Preparation
Serving liver in large, unmanageable chunks can pose a choking hazard. Cats may try to swallow large pieces whole. Always ensure the cooked liver is cut into small, pea-sized or kibble-sized pieces. Furthermore, if you are feeding liver as a supplement, you must account for its caloric and nutritional value. Failing to do so can lead to overfeeding, weight gain, and nutritional imbalances if it displops the intake of their primary, balanced food.
Can Kittens Eat Liver?
When considering feeding liver to kittens, the same principles of caution and moderation apply, but with an even greater emphasis on safety and nutritional balance. Kittens are in a critical stage of development, and their dietary needs are highly specific and sensitive. While liver is nutrient-dense and can provide beneficial vitamins and minerals, it should be introduced with extreme care.
The primary concern with feeding liver to kittens is the risk of Vitamin A toxicity. Their small bodies are less able to process large amounts of nutrients, making them more susceptible to imbalances. Overfeeding Vitamin A can lead to severe developmental issues, including bone deformities, which can be permanent and debilitating for a growing kitten. Therefore, if liver is to be offered, it must be in minuscule quantities, significantly less than what would be given to an adult cat, and only after consulting with a veterinarian.
Another crucial consideration for kittens is their developing digestive system. Raw liver, with its associated bacterial risks, is generally not recommended for kittens due to their more vulnerable immune systems. Cooked, plain liver, cut into extremely small pieces, is the only viable option if liver is to be considered at all. However, many veterinary professionals advise against feeding organ meats like liver to very young kittens, recommending they stick to kitten-specific, veterinarian-approved food until they are older and their systems are more robust.
The best diet for a kitten is a high-quality, commercially prepared kitten food that is specifically formulated to meet their unique nutritional requirements for growth and development. This food provides all the essential nutrients in the correct proportions, ensuring healthy development without the risks associated with inappropriate supplementation. If you are considering adding liver or any other food to a kitten's diet, it is imperative to seek professional advice from your veterinarian. They can guide you on what is safe, appropriate, and beneficial for your kitten's specific needs, ensuring they grow into a healthy adult cat.
Always consult your veterinarian before giving any new food, especially organ meats like liver, to a kitten.
Kitten Nutritional Needs
Kittens require a diet that supports rapid growth, brain development, and a strong immune system. This typically means food that is higher in calories, protein, fats, vitamins, and minerals than adult cat food. Key nutrients include higher levels of protein for muscle and tissue development, DHA for brain and vision development, and specific balances of calcium and phosphorus for bone growth. Introducing liver prematurely or in incorrect amounts can disrupt this delicate nutritional balance, potentially causing harm rather than benefit.
Risks for Young Kittens
The risks of Vitamin A toxicity are amplified in kittens. Their developing organs and metabolic systems are less capable of handling high concentrations of fat-soluble vitamins. Furthermore, their digestive systems are more sensitive to bacterial pathogens found in raw meat. Any illness or imbalance during this critical growth phase can have long-lasting consequences on their health and development. Therefore, strict adherence to a veterinarian-recommended kitten diet is the safest course of action.
Veterinary Guidance is Crucial
When it comes to kittens, veterinary guidance is not just recommended; it's essential. Your vet can provide specific recommendations for the best kitten food, advise on portion sizes, and offer expert advice on whether and how to introduce treats or supplements like liver. They can also monitor your kitten's growth and development, catching any potential issues early on. For questions like 'what human food can kittens eat?', the safest answer is usually 'very little' and always under veterinary supervision.
Frequently Asked Questions About Cats and Liver
Understanding the specifics of feeding liver to cats can bring up many questions. Here are answers to some of the most common concerns, providing clarity on this nutrient-rich food item.
Can cats have liver?
Yes, cats can eat liver, but it must be given in moderation and prepared correctly. Liver is highly nutritious, offering essential vitamins and minerals, but its high Vitamin A content means overfeeding can lead to toxicity. It should only be offered as an occasional treat, not a dietary staple.
Is cooked liver safe for cats?
Cooked liver is generally safer for cats than raw liver. Cooking neutralises potential harmful bacteria like Salmonella and E. coli. It's crucial to cook liver thoroughly without any added seasonings, oils, or fats. Plain, cooked liver, cut into small pieces, is the safest way to serve it.
How often can I feed my cat liver?
Liver should be fed infrequently, perhaps only a couple of times per week at most. It should constitute a very small portion of their overall diet, typically no more than 5-10% of their daily caloric intake. Think of it as a small, occasional treat rather than a regular part of their meals.
What are the dangers of too much liver for cats?
The primary danger of feeding too much liver is Vitamin A toxicity, also known as hypervitaminosis A. This can lead to painful bone spurs, joint stiffness, lethargy, and other serious health issues. It can also cause gastrointestinal upset due to its richness. Over-reliance on liver can also create an imbalance in their diet, leading to deficiencies in other essential nutrients.
Can cats eat raw liver?
While some cats may tolerate raw liver, it is not recommended due to the significant risk of bacterial contamination. Raw meat can harbour pathogens such as Salmonella, E. coli, and Listeria, which can cause severe illness in cats and pose a risk to human household members. Cooked liver is a much safer alternative.
