What Food Can I Feed My Cat? A Complete Guide

What Food Can You Feed Your Cat? Start Here.

As a cat's pet parent, one of the most important decisions you make every day is what goes in her food bowl. Cats are obligate carnivores — meaning their bodies are built to run on animal-based protein and they cannot thrive on plant-based diets alone https://www.merckvetmanual.com/management-and-nutrition/nutrition-small-animals/nutritional-requirements-of-small-animals. That biological reality shapes every food choice you'll make for her, from kittenhood through her senior years.

The good news: there's no single "right" answer that fits every cat. The right food for your cat depends on her life stage, health status, activity level and even her personal preferences. What matters most is that the food you choose is complete and balanced — and that you revisit that choice as her needs change over time.

The Main Types of Cat Food (and When Each Makes Sense)

Understanding your options is the fastest way to narrow down what to feed your cat. Here's a plain-language breakdown of the major categories you'll find when you browse cat food:

Explore wet cat food options if your cat tends to drink very little water on her own — moisture in food is one practical way to support her daily hydration.

How to Know If a Cat Food Is Nutritionally Complete

Not all cat foods are created equal. Look for an AAFCO nutritional adequacy statement on the label — a line that confirms the food meets established nutrient profiles for cats at a specific life stage (kitten, adult or all life stages) https://www.aafco.org/consumers/understanding-pet-food/. The FDA also regulates pet food labeling, so that statement carries real weight https://www.fda.gov/animal-veterinary/animal-foods-feeds/pet-food.

A complete and balanced food will cover your cat's needs for:

• Protein — the foundation of a cat's diet; look for a named animal protein (chicken, salmon, turkey) as the first ingredient
• Taurine — an essential amino acid cats cannot produce on their own; must be present in the food https://www.merckvetmanual.com/management-and-nutrition/nutrition-small-animals/nutritional-requirements-of-small-animals
• Arachidonic acid — an essential fatty acid cats cannot synthesize from plant sources
• Vitamins A and D — cats cannot convert beta-carotene to vitamin A the way dogs can, so preformed vitamin A from animal sources is required
• Moisture — especially important for a species with a naturally low thirst drive

Quick Cat Food Finder: Match Your Cat to Her Food

Use these questions to point yourself toward the right starting place — then confirm the final choice with your veterinarian, especially if your cat has any health concerns.

1. How old is your cat?

• Kitten (under 1 year): Choose a food labeled for kittens or "all life stages" — she needs more protein, calories and certain nutrients to support rapid growth.
• Adult (1–7 years): A complete and balanced adult formula supports her maintenance needs.
• Senior (7+ years): Many senior cats benefit from higher protein to maintain muscle mass and adjusted phosphorus levels; ask your vet what's right for her specifically https://www.vet.cornell.edu/departments-centers-and-institutes/cornell-feline-health-center/health-information.

2. Does she have any health conditions?

• If yes — kidney disease, diabetes, urinary issues, weight concerns or food sensitivities — work with your veterinarian before choosing a food. A prescription diet may be the most appropriate option.
• If no — a complete and balanced commercial food is a solid starting point.

3. What texture does she prefer?

• Dry kibble, wet/canned, a mix of both (often called "combination feeding"), raw or fresh — cats can be particular. Texture preference is a real factor in whether she'll actually eat what you serve.

4. What does your budget allow?

• Price doesn't always equal quality, but look for foods from manufacturers who follow World Small Animal Veterinary Association (WSAVA) nutrition guidelines as a benchmark for rigorous quality standards https://wsava.org/global-guidelines/global-nutrition-guidelines/.

A note from our Petco associates: Nutrition is one of the most meaningful ways you care for your cat every single day. If you're ever unsure which food is the right fit — especially after a health diagnosis or a big life change like a new kitten or a newly adopted senior — your veterinarian is your best resource. Our knowledgeable Petco associates are also here to help you compare options in store or online.

While your veterinarian is always your best resource for a personalized nutrition plan, understanding the main categories of cat food — and what sets them apart — helps you make a more confident choice at the shelf. Here's a practical look at what you can feed your cat, organized by food type, so you can match the right option to your cat's life stage, health status and preferences:

• Dry food (kibble): Convenient, shelf-stable and often more budget-friendly. Look for a named animal protein (such as chicken or salmon) as the first ingredient and an AAFCO nutritional adequacy statement confirming it meets your cat's life stage requirements https://www.aafco.org/consumers/understanding-pet-food/.
• Wet food (canned or pouched): Higher moisture content can help support healthy hydration, which matters for cats — who are naturally low-thirst drinkers https://www.vet.cornell.edu/departments-centers-and-institutes/cornell-feline-health-center/health-information. Explore wet cat food options if your cat needs extra fluid intake or simply prefers a softer texture.
• Mixed feeding (dry + wet): Combining both formats gives your cat the hydration benefits of wet food alongside the convenience of dry. Portion each accordingly so total daily calories stay on target.
• Raw and fresh diets: These require careful handling and sourcing to minimize food-safety risks; consult your veterinarian before transitioning https://www.fda.gov/animal-veterinary/animal-foods-feeds/pet-food.
• Prescription and therapeutic diets: Formulated to address specific health conditions and available only through a veterinarian's recommendation — never substitute a therapeutic diet without professional guidance.

Because cats are obligate carnivores, every option you choose should deliver adequate animal-sourced protein and essential nutrients like taurine and arachidonic acid that cats cannot synthesize on their own https://www.merckvetmanual.com/management-and-nutrition/nutrition-small-animals/nutritional-requirements-of-small-animals.

How to feed your kitten

To help your kitten meet their daily nutritional needs, most veterinarians recommend feeding them three meals a day. Because a kitten's stomach is smaller than that of an adult cat's, this helps ensure they receive an adequate amount of calories and nutrients.

To determine how much to give your kitten at each meal, check your kitten food package for the daily recommended amount. Split the total daily amount of food into three equal portions, and feed these at evenly spaced intervals throughout the day: one meal in the morning, one mid-day and one in the evening, for example. As your kitten approaches 10 to12 months old, you can switch to feeding just two meals a day—one in the morning and one evening.

Whichever intervals you choose, try to keep them consistent each day. A routine feeding schedule promotes healthy eating habits and enables you to control your kitten’s diet and monitor their development and weight gain.

Avoid Free Feeding Unless Recommended By a Vet

Many cat parents find they can leave a full bowl of food out in the morning, and their adult cat will self-manage their diet, eating as they feel hungry and stopping when they feel full. This is called free feeding, and while it can work well for adult cats who are already at a healthy weight and have no trouble maintaining that, it's usually not advised for kittens as they haven't yet learned how to listen to their body's hunger signals. For very young kittens (under the age of four months) who are underweight or growing more slowly than expected, a veterinarian may recommend free feeding to lower the risk of rapid eating (which may lead to stomach distention) and help underdeveloped kittens get the calories they need.

Consult your veterinarian if you think this might be best for your pet.

Feed Your Kitten Alone, Separate from Other Pets

If you live in a multi-pet household, feed your kitten separately from the other pets in the home. Close off one room at your kitten’s mealtime, or set up a baby gate, pen or area that other pets cannot access while your kitten eats.

This is important for both your kitten’s growth and the health of your other furry family members. Many animals, including adult cats and dogs, may be enticed by the flavors and fatty content of kitten food. If a different pet gets into the kitten’s food bowl, your kitten won’t get the full nutritional value they need—and the other pet is at risk of indigestion, obesity or other health issues, as kitten food contains more calories than most animals should receive.

To make the switch to adult cat food, start by feeding your kitten approximately 75 percent of their regular kitten food mixed with 25 percent of the new adult food. After about three days, increase the ratio of adult to kitten food so that your kitten is eating 50 percent of each. In another three days, increase the ratio again: to 75 percent of the adult cat food and only 25 percent of the kitten food. After a few days, you can switch to entirely adult cat food.

Protein is Key

Cats are carnivores. Meat and protein should make up a big chunk of their diet. Protein can come from a variety of sources, including plant matter, so make sure the bulk of the protein is derived from meat and poultry. These ingredients are not necessarily inferior – it all depends on how the ingredients are arranged according to their amino acid profile. They also need certain essential amino acids that their bodies can't produce. One of the most important of these is taurine.

A lack of taurine in the protein can cause serious health problems in cats, including cardiomyopathy (or weakened heart muscle disease), reproductive disorders, retinal degeneration or blindness. Feeding your kitty a premium food is your best insurance against taurine deficiency because premium food manufacturers make sure their brands give your cat the taurine levels needed, plus the correct balance of other nutrients.

Avoid an All-Meat or All-Vegetarian Diet

Cats are carnivores. They require high animal protein diets. A vegetarian diet will not provide adequate nutrition for your cat due to your cat's very specific gastrointestinal system and nutrient requirements.

Cats must also get nutrients from foods other than meat. Without proper calcium, phosphorus and vitamin D (not available in a meat-only diet), your cat will be susceptible to a multitude of serious health concerns.

Your Cat’s Changing Dietary Needs

As your kitten reaches adulthood, nutritional needs change. They'll need less protein and fat, and fewer calories. You can switch your cat to an adult food at age one.

Your pet’s digestive system can handle a limited number of food types at a time if you consistently feed them the same food and treat options. They will need a short period of introduction when introducing new recipes to their palette to ensure a smooth transition for digestion. When switching food, make the swap over a two-week period to give your cat time to adjust to their new meal. Each time mix in more and more of the new food as you decrease the amount of original food.

Food sensitivities

Before making any changes, you'll want to meet with your veterinarian to determine the right steps to take. Some helpful steps may include skin testing or feeding research, to determine which substances your cat may be sensitive to. Sometimes it can be as simple as switching cat food.

Final thoughts on cat nutrition

When you’re ready to get started with a new food, remember to slowly transition your cat over a period of about 10 days. And don’t forget that Petco has all the base foods, toppers and treat options your cat could want. Plus Petco’s money-back guarantee means you won’t waste money while you search. If your pet doesn’t like what you get, just bring the remaining food back for a full refund. Bon appetit!
