Understanding Your Cat's Nutritional Needs
Cats are obligate carnivores, a biological classification that dictates their dietary requirements. This means their bodies are designed to derive nutrients almost exclusively from animal tissues. Unlike omnivores such as dogs or humans, cats cannot efficiently digest or derive necessary nutrients from plant matter. Their physiology is geared towards processing meat, which provides them with essential amino acids, fatty acids, and vitamins that are difficult or impossible for them to synthesise themselves. For instance, taurine, an amino acid vital for heart function and vision, must be obtained from animal sources; cats cannot produce enough of it on their own.
This fundamental characteristic means that the food you provide for your feline companion must be rich in animal protein. A diet lacking sufficient animal-based nutrients can lead to serious health issues, including heart disease, vision problems, and developmental defects. Therefore, the primary answer to 'what do cats eat' is animal protein, presented in a digestible and balanced form. Understanding this basic principle is the first step to ensuring your cat receives appropriate nutrition that supports their health from kittenhood through to senior years.
- Cats are obligate carnivores requiring a meat-based diet.
- Essential nutrients like taurine must come from animal sources.
- Plant-based foods are poorly digested and insufficient.
- Proper nutrition prevents serious health issues.
The specific nutritional breakdown recommended by veterinarians typically includes high levels of protein, moderate fats, and very low carbohydrates. Cats have a limited ability to process carbohydrates, and diets high in them can contribute to obesity and metabolic disorders. Animal fats are a concentrated source of energy and are crucial for absorbing fat-soluble vitamins (A, D, E, K). Proteins not only provide energy but also supply essential amino acids that are the building blocks for tissues and enzymes.
Key Nutrients for Feline Health
Beyond protein and fat, several micronutrients are vital. Vitamins such as Vitamin A (pre-formed, found in animal tissues), B vitamins (especially important for metabolism), and Vitamin E (an antioxidant) are critical. Minerals like calcium and phosphorus are essential for bone health, but their balance is just as important as their presence. Trace minerals like iron, zinc, and selenium also play crucial roles in various bodily functions.
Water is, of course, paramount. Cats have a naturally low thirst drive, often stemming from their wild ancestors who obtained most of their moisture from prey. This makes it vital to ensure their diet contributes to hydration. Wet food typically has a much higher moisture content than dry kibble, which can be a significant benefit for cats prone to urinary tract issues or kidney problems.
Types of Cat Food Explained
When considering what do cats eat, the market offers several primary formats for cat food, each with its own advantages and disadvantages. These are typically categorised as wet food (canned or pouch), dry food (kibble), and semi-moist food. Each type is formulated to meet AAFCO (Association of American Feed Control Officials) standards for specific life stages, but the form can significantly impact your cat's intake and overall health.
Wet cat food, often referred to as canned food, generally contains a higher percentage of protein and a significantly higher moisture content (around 70-80%) compared to dry food. This high moisture level is beneficial for feline hydration, supporting kidney and urinary tract health. It also often mimics the natural moisture content of prey, making it a palatable and digestible option for many cats. Flavours and textures vary widely, catering to even the pickiest eaters. However, once opened, wet food can spoil quickly and needs to be refrigerated, and it can be more expensive per serving than dry food.
Dry Cat Food (Kibble)
Dry cat food, or kibble, is convenient, cost-effective, and can be left out for cats to graze on throughout the day, which suits some cats' feeding behaviours. It typically has a moisture content of around 10%, meaning cats consuming kibble must drink significantly more water. Kibble can also contribute to dental hygiene by helping to scrape plaque off teeth, although this effect is often overstated for many commercial products. The primary concern with dry food is its lower moisture content, which can be a disadvantage for cats not inclined to drink enough water, potentially increasing the risk of urinary issues.
The manufacturing process for kibble often involves high heat, which can degrade some nutrients, although manufacturers typically add them back in during formulation. It's crucial to choose a high-quality kibble that uses meat as its primary ingredient and avoids excessive fillers like corn, wheat, or soy, which offer little nutritional value to cats and can be harder for them to digest. Always ensure fresh water is readily available if feeding dry food.
Ensure fresh, clean water is always accessible, especially if your cat primarily eats dry food. Consider a pet drinking fountain, as the moving water can encourage some cats to drink more.
Semi-Moist Cat Food
Semi-moist cat foods fall between wet and dry in terms of moisture content, usually around 30-40%. They often come in appealing shapes and flavours and are highly palatable. However, they frequently contain more artificial colours, flavours, and preservatives to maintain their texture and appeal. Due to these additives and their moderate moisture content, they are generally not considered the optimal choice for a cat's primary diet compared to high-quality wet or dry food options.
The best cat food is one that meets your cat's specific nutritional needs, considering their age, activity level, and health status, while being palatable and digestible.
When choosing between food types, consider your cat's individual needs. Kittens require food formulated for growth, while senior cats may benefit from diets tailored to their changing metabolism and potential health concerns. Cats with specific conditions like urinary issues, kidney disease, or allergies might require prescription diets formulated by veterinary nutritionists.
What Foods Are Safe for Cats?
Beyond commercially prepared cat foods, pet owners often wonder about offering their cats supplementary treats or human foods. While cats are obligate carnivores, certain human foods can be safely incorporated into their diet in moderation, provided they are not toxic and are prepared appropriately. The key is to remember that these should be occasional additions, not staples, and should never replace a balanced cat food formulation.
Meat is generally safe and beneficial, as it aligns with a cat's natural diet. Small, cooked, unseasoned portions of chicken, turkey, or beef can be offered as treats. Ensure all meat is thoroughly cooked to eliminate the risk of bacterial contamination like salmonella or E. coli, which can be present in raw meat. Avoid giving cats meat that has been seasoned with garlic, onions, or strong spices, as these can be harmful.
Specific Food Items and Considerations
Can cats eat tuna? Yes, but only in very small quantities and infrequently. Tuna, especially canned tuna in brine or water, lacks essential nutrients like Vitamin E and can be high in mercury. It's considered a treat rather than a meal replacement. Regular consumption of tuna can lead to malnutrition or mercury poisoning.
Can cats eat eggs? Cooked eggs are a good source of protein and can be given as an occasional treat. Ensure they are fully cooked, as raw eggs contain avidin, which can interfere with biotin absorption, and carry a risk of salmonella. Avoid feeding raw eggs.
Can cats eat cheese? Most cats are lactose intolerant, meaning they have difficulty digesting lactose, the sugar found in milk. While small amounts of certain cheeses (like cheddar or mozzarella) might not cause immediate harm, they offer little nutritional benefit and can lead to digestive upset such as diarrhoea or vomiting. It's generally best to avoid dairy products.
Can cats eat bananas? Bananas are safe for cats in very small amounts. They are high in potassium and fibre but also sugar. A tiny slice as an occasional treat is unlikely to cause harm, but they are not a significant source of essential nutrients for cats and should be given sparingly.
Can cats eat watermelon? Yes, watermelon is safe for cats in small quantities. It's mostly water and can be a hydrating treat, especially in hot weather. Ensure you remove the rind and seeds, as these can pose choking hazards or cause digestive blockage.
Can cats eat strawberries? Strawberries are safe for cats in moderation. They contain antioxidants and fibre. Offer a small piece as an occasional treat, ensuring it's washed and any stems are removed.
Can cats eat raw chicken? While cats in the wild eat raw prey, feeding raw chicken at home carries significant risks of bacterial contamination for both the cat and the humans handling the food. Pathogens like Salmonella and E. coli can cause severe illness. If considering a raw diet, it must be done under strict veterinary guidance with specially prepared, pathogen-tested raw food diets to minimise risks.
Foods That Are Toxic to Cats
While many human foods are safe in moderation, some are highly toxic to cats and can cause severe illness or even death. It is crucial to be aware of these dangers to prevent accidental poisoning. Always keep toxic substances out of reach and never feed them to your cat.
Can cats eat chocolate? Absolutely not. Chocolate contains theobromine and caffeine, both stimulants that cats cannot metabolise effectively. Dark chocolate and baking chocolate are particularly dangerous due to their high theobromine content. Ingestion can lead to vomiting, diarrhoea, tremors, seizures, and even death.
Onions, Garlic, Leeks, and Chives: These allium vegetables, whether raw, cooked, or in powdered form, can damage a cat's red blood cells, leading to anaemia. Symptoms may not appear immediately but can develop over a few days and include lethargy, weakness, and pale gums. Garlic is considered more toxic than onions.
Grapes and Raisins: These fruits are extremely dangerous for cats, even in small amounts. They can cause acute kidney failure. Symptoms include vomiting, lethargy, and decreased appetite. The exact toxic component is unknown, but ingestion requires immediate veterinary attention.
Alcohol and Yeast Dough: Alcoholic beverages can cause intoxication, leading to vomiting, diarrhoea, disorientation, and breathing difficulties. Raw yeast dough can rise in the stomach, causing severe bloating and potential rupture, and also produces alcohol as it ferments.
Bones and Cooked Bones: While natural bones might seem like a safe chew, cooked bones can splinter and cause choking, or internal blockages and lacerations in the digestive tract. Raw bones can also pose risks and should only be considered under strict veterinary guidance.
Nuts and Seeds: Many nuts contain high levels of fat, which can cause digestive upset. Macadamia nuts are toxic to cats. Nuts and seeds can also be choking hazards.
Certain Plants: Many common houseplants are toxic to cats, including lilies, tulips, daffodils, and poinsettias. If ingested, they can cause a range of symptoms from mild gastrointestinal upset to severe organ damage or death. Always check if a plant is toxic before bringing it into a home with cats.
Keep a list of emergency veterinary contact numbers and the Pet Poison Helpline or equivalent service readily available in case of suspected poisoning.
If you suspect your cat has ingested something toxic, contact your veterinarian or an animal poison control centre immediately. Do not wait for symptoms to appear, as prompt treatment significantly improves the prognosis.
Feeding Your Cat: Practical Advice
Ensuring your cat eats well is about more than just selecting the right food; it involves establishing healthy feeding habits and understanding your cat's behaviour. The goal is to provide a balanced diet that supports their health while making meal times a positive experience.
Portion Control is Key: Overfeeding is a common problem, leading to obesity, which is linked to numerous health issues like diabetes, arthritis, and heart disease. Always follow the feeding guidelines on your cat's food packaging as a starting point. These are usually based on the cat's weight and activity level. However, your veterinarian can provide more precise recommendations tailored to your individual cat's needs.
Feeding Schedule: Some cats do best with scheduled meals twice or three times a day. This helps regulate their digestion and can prevent overeating. Free-feeding, where food is left out all day, can work for some cats but often leads to obesity and makes it difficult to monitor food intake or detect changes in appetite, which can be an early sign of illness.
Water Availability: As mentioned, ensuring constant access to fresh, clean water is non-negotiable. If your cat is reluctant to drink from a bowl, try a pet drinking fountain. Some cats prefer running water, and fountains also help keep the water aerated and fresher.
Transitioning to New Food
If you need to change your cat's food, do so gradually to avoid upsetting their digestive system. This process typically takes about a week. Start by mixing a small amount of the new food with their current food. Over several days, gradually increase the proportion of the new food while decreasing the old food. For example:
- Days 1-2: 25% new food, 75% old food
- Days 3-4: 50% new food, 50% old food
- Days 5-6: 75% new food, 25% old food
- Day 7 onwards: 100% new food
Monitor your cat for any signs of digestive upset, such as vomiting or diarrhoea, during the transition. If these occur, slow down the process or revert to the previous ratio.
Veterinary Consultations: Regular check-ups with your veterinarian are essential. They can assess your cat's body condition, discuss their diet, and recommend specific foods or supplements if needed. They are your best resource for understanding what do cats eat in the context of your specific pet's health.
Common Feeding Pitfalls to Avoid
Many well-meaning cat owners inadvertently make mistakes that can impact their pet's health and well-being. Being aware of these common pitfalls can help you provide the best possible care for your feline friend.
Relying Solely on Dry Food: While convenient, a diet exclusively of dry kibble can lead to chronic mild dehydration, potentially increasing the risk of urinary tract issues and kidney disease over time. It's advisable to supplement dry food with wet food or ensure your cat drinks ample water. Remember that cats' natural prey is high in moisture.
Over-reliance on Human Food Scraps: Offering table scraps can be problematic for several reasons. Many human foods are too high in salt, fat, or spices for cats. Some, as covered earlier, are toxic. Even 'safe' foods, if given too frequently or in large amounts, can unbalance a cat's diet, leading to nutritional deficiencies or excesses, and can contribute to obesity.
Ignoring Food Allergies or Sensitivities: Just like humans, cats can develop allergies or sensitivities to certain ingredients, often proteins like chicken, beef, or fish. Symptoms can include digestive upset (vomiting, diarrhoea), skin issues (itching, hair loss), or respiratory problems. If you suspect an issue, consult your vet. They may recommend an elimination diet to identify the culprit ingredient.
Not Considering Life Stage Needs: A kitten has very different nutritional requirements from an adult or a senior cat. Kittens need more calories, protein, and specific nutrients for growth. Senior cats may benefit from diets lower in calories but higher in easily digestible protein, or those supporting joint health. Feeding an inappropriate life-stage diet can lead to health problems.
Assuming All 'Cat Food' is Equal: The quality of commercial cat foods varies dramatically. Look for foods where a specific meat source (e.g., chicken, salmon) is the first ingredient. Avoid foods that list excessive grains, corn, or vague 'meat by-products' as primary components. Reputable brands often conduct feeding trials and adhere to strict quality controls.
Using the Wrong Type of Milk: The question 'can cats drink milk' is often asked. While kittens drink their mother's milk, most adult cats are lactose intolerant. Cow's milk contains lactose, which they cannot digest properly, often leading to an upset stomach. Special 'lactose-free' cat milk alternatives are available and are a safer choice if you wish to offer a milky treat, but water remains the best choice for hydration.
Not Monitoring Weight: Cats can gain weight subtly. Regularly assessing your cat's body condition – feeling their ribs, observing their waistline – is vital. An overweight cat is at higher risk for numerous health issues. If you notice weight gain, adjust portion sizes and consult your vet.
