Key Takeaways
- Cats are obligate carnivores, which means meat-based protein should form the foundation of their diet rather than plant-based ingredients.
- Feed smaller portions more often. A cat’s stomach is small relative to its body, and grazing suits its natural eating pattern.
- Always provide fresh, clean water in a separate bowl, and expect a cat on dry food to drink noticeably more.
- A complete and balanced commercial food is the simplest way to meet a cat’s full nutritional needs. Treats and table foods should stay minimal.
- Talk to your veterinarian before making major diet changes or adding supplements, since individual needs vary by age, weight, and health.
How you feed your cat shapes almost everything you can see about its health. A well-fed cat carries a trim, balanced body, stays alert and playful, and digests its food without trouble. By contrast, sluggishness, sudden weight loss, weight gain, or digestive upset can all be signals that something in the diet is off. One thing sets cats apart from many other pets: they are true carnivores, and protein makes up a large share of their diet, roughly 35 percent of what they eat.
What Cats Eat in the Wild
Like most predators, wild and feral cats live almost entirely on meat and organ tissue. Their teeth are built for gripping and tearing prey into pieces, not for grinding or chewing the way an omnivore’s teeth are. A cat hunting on its own tends to catch small animals, mostly mammals, along with the occasional bird or insect. Understanding this natural diet helps explain why a house cat thrives on meat-rich food and does poorly on a diet built around grains or vegetables. As the Cornell Feline Health Center notes, cats are obligate carnivores with nutritional requirements that a meat-based diet is designed to meet.
Setting a Feeding Routine
Most cats do best with several small meals spread across the day rather than one or two large ones. How much food a cat needs depends on several factors, including its age and activity level, its overall condition, and its metabolism. Many adult house cats need somewhere in the range of 250 to 300 calories a day, though your veterinarian can give you a target tailored to your individual cat.
It helps to give your cat its own dish and place a mat underneath it. Many cats, echoing how they would handle prey in the wild, pull pieces of food out of the bowl to tear them apart before eating, and that habit can be hard on flooring and carpets. A mat keeps the mess contained and gives your cat a consistent spot to eat.
Because a cat’s stomach is fairly small compared with its body, smaller and more frequent portions work better than large ones. Offer too much at once and many cats will bolt the food down as fast as possible, which often ends with it coming right back up. In a multi-cat home, watch the group dynamic as well. Personalities differ, and a bolder cat may crowd out a more easygoing one. If that happens, set up separate feeding spots so everyone gets a fair share.
Water
Fresh, clean water should always be available, ideally in a bowl of its own set apart from the food. Some cats turn up their noses at plain tap water because the treatments that keep it safe to drink can leave a noticeable smell or taste. If your cat seems reluctant, a couple of simple fixes can help: offer filtered water, or place the water bowl a short distance from the food so it stays appealing. Many cats also prefer moving water, which is why a pet fountain can encourage a fussy drinker. Keeping a cat well hydrated matters, and the ASPCA stresses that constant access to fresh water is a basic part of good cat care.
Vitamins and Nutrients
To grow and stay healthy, a cat needs a range of vitamins, and each one has its own role and food sources. Vitamins A, B, C, D, and E, along with the right balance of proteins, fats, and carbohydrates, all contribute to healthy cells, a strong immune system, and normal reproductive function. In a balanced diet these nutrients tend to fall into place on their own. A quality complete-and-balanced cat food is formulated to supply them in the right amounts, so most cats do not need extra supplements. In fact, adding vitamins on your own can do more harm than good, so check with your veterinarian before giving any. The American Veterinary Medical Association is a good starting point for general guidance on pet nutrition.
Meat and Fish
Most feline nutrition experts agree that if you offer fish, it should be cooked and free of bones and skin, and served at room temperature rather than cold or hot. Fish provides a good source of the healthy oils cats benefit from, and it can be paired with a small amount of grains or cereal to round out a meal in a way most cats will accept more readily than those ingredients on their own. Keep fish an occasional item rather than a staple, since a fish-only diet can lead to nutritional imbalances.
When it comes to meat, most lean cuts and many organ meats are suitable, provided they are cooked and served plain, without seasoning, onions, or garlic. Cook meat thoroughly rather than serving it raw, which reduces the risk of harmful bacteria. Eggs can add nourishment too, and a cooked yolk is an easy, occasional addition to a meal.
Dairy Products
Milk does contain protein and a number of nutrients cats can use, but the classic image of a cat lapping up a bowl of milk is misleading. Many adult cats are lactose intolerant, which makes cow’s milk hard to digest and can lead to stomach upset. Some cats also simply do not like it. If your cat tolerates dairy, small amounts of goat’s milk, cream, or a specially made cat-milk substitute may sit better than regular cow’s milk. Kittens are a different case, as they need the higher concentration of nutrients that comes with milk during early development. When in doubt, treat dairy as an optional extra rather than a dietary necessity.
As a small, well-liked treat, a bit of cheese is something most cats enjoy, though it too should stay an occasional indulgence rather than a regular part of the diet.
Protein From Different Sources
Cats need animal protein at the center of their diet. Because they are natural predators, they cannot rely on plant protein the way people or dogs can. Some plant-based ingredients can appear in a balanced food as a supporting element, but they should never take the place of meat. When you build meals or choose a food, keep animal protein as the main event and treat everything else as a complement.
Vegetables and Grains
Cats need only small amounts of vegetables and grains, and these are best mixed into the main dish rather than served on their own. They add a little variety and fiber, but they are a minor part of a healthy feline diet, not a foundation.
Dry, Wet, and Canned Food
The pet food market is broad and well developed, which makes it fairly easy to find a good, suitable diet for almost any cat. The industry has matured over decades, and reputable manufacturers invest heavily in research on how their formulas affect cats of different breeds, ages, and life stages. Most commercial cat foods are built around a mix of different meats, cereals, and vegetables. Here is how the main types compare.
| Type | Moisture | Best for | Keep in mind |
|---|---|---|---|
| Dry food (kibble) | Low | Convenience, free-feeding, budget | Cats on dry food need noticeably more water |
| Wet food | High | Hydration, picky eaters, dental issues | Spoils quickly once opened; refrigerate leftovers |
| Canned food | High | Complete meals, long shelf life unopened | Watch portion sizes to avoid overfeeding |
Most cats readily take to a good commercial food. If you feed dry food, remember that your cat will need to drink more water to make up for the lack of moisture. The shelves are also full of specialty products, from supplements to functional foods and treats. It is fine to reward a cat with a treat now and then, including during training, but do not overdo it. Too many treats can throw off the nutritional balance of an otherwise good diet.
Whenever you switch foods, do it gradually over about a week and watch how your cat responds. If a new food seems to cause digestive trouble or other problems, ease back to the previous diet and let the manufacturer know, since that feedback helps them improve. Above all, keep an eye on your cat’s condition over time, and check in with your veterinarian whenever something changes. Care and attention at mealtime go a long way toward a long, healthy life.
Frequently Asked Questions
How often should I feed my cat?
Most adult cats do well with two to three small meals a day, or with measured portions offered a few times daily. Because a cat’s stomach is small, frequent smaller portions suit its natural eating pattern better than one large meal. Kittens generally need to eat more often. Your veterinarian can recommend a schedule based on your cat’s age and needs.
Can cats drink milk?
Many adult cats are lactose intolerant, so regular cow’s milk can cause stomach upset even though they may enjoy the taste. If you want to offer dairy, small amounts of a cat-specific milk substitute, goat’s milk, or cream tend to be gentler. Kittens are the exception, as they rely on milk during early development.
Is dry or wet food better for cats?
Both can be part of a healthy diet as long as they are complete and balanced. Dry food is convenient and stores well, but cats eating it need to drink more water. Wet and canned foods add valuable moisture and often appeal to picky eaters. Many owners feed a combination. Your veterinarian can help you decide what fits your cat best.
Do cats need vitamin supplements?
A quality complete-and-balanced cat food already supplies the vitamins and minerals a healthy cat needs, so extra supplements are usually unnecessary and can even be harmful in excess. Only give supplements if your veterinarian recommends them for a specific reason.
How many calories does a cat need each day?
Many adult house cats need roughly 250 to 300 calories a day, but the right amount varies with age, activity level, weight, and health. Use this only as a rough guide and ask your veterinarian for a target suited to your individual cat.
