What Can Cats Eat? A Simple Guide to Safe and Unsafe Foods

It is tempting to share a little of your food when your cat looks interested in what is on your plate. Some plain foods can be offered occasionally, but others may upset your cat’s stomach or pose a more serious risk.

Cats also have specific nutritional needs. Knowing which foods are safe is useful, but it does not by itself make a complete diet. Here’s a straightforward guide to common foods, ingredients to keep away from cats and what to consider when planning their meals.

What should a cat’s everyday diet include?

Cats are obligate carnivores: they rely on nutrients found in animal tissues and have dietary requirements that differ from those of dogs and people. A suitable everyday diet needs to provide the nutrients a cat requires in the right amounts and proportions.

That is why a food’s label matters. Look for a product described as complete for your cat’s life stage. A complementary food, treat or single ingredient is not designed to provide everything your cat needs as its main diet.

Cats’ needs can vary with age, body condition, activity, pregnancy and health. If your cat has a medical condition, is losing or gaining weight unexpectedly, or needs a prescribed diet, ask your vet before changing their food.

Foods cats can usually eat in small amounts

Some plain, properly prepared foods may be suitable as an occasional treat for many cats. They should not replace a complete cat food or make up a large part of the diet.

• Cooked chicken or turkey: Offer boneless meat with no seasoning, skin-heavy portions or sauces.
• Cooked fish: A small amount of plain, thoroughly cooked fish can be an occasional treat. Remove all bones and avoid oily, salted or smoked preparations.
• Cooked egg: A little plain, fully cooked egg may be offered now and then.
• A few vegetables: Some cats may nibble small portions of plain, cooked vegetables, but vegetables are not a substitute for the animal-based nutrients cats need.
• Fresh water: Keep clean water available. Some cats drink more readily from a wide bowl or a pet fountain.

Introduce any new food in a small amount and offer only one new item at a time. Stop if your cat seems unwell, and contact your vet if you notice concerning symptoms.

Foods and ingredients to avoid

Keep the following away from your cat:

• Onions, garlic, leeks and chives, including cooked, powdered or dried forms. They can damage red blood cells.
• Chocolate, cocoa, coffee and other caffeinated products. These can be harmful to cats.
• Alcohol. Even small amounts can be dangerous.
• Grapes and raisins. Keep them out of reach; the potential risk is not worth testing.
• Foods containing xylitol, a sweetener found in some sugar-free products. Avoid giving cats products containing it.
• Cooked bones. They can splinter or cause choking, injury or digestive problems.
• Raw meat, raw fish and raw eggs. These may carry harmful bacteria or parasites, and raw fish can present additional nutritional concerns.
• Highly salted, seasoned, fatty or heavily processed foods. These are not suitable treats for cats and may cause problems.

Pawlate’s pet-safety information also lists items such as macadamia nuts, avocado pits and skin as prohibited. As a practical rule, do not offer unfamiliar foods or leftovers unless you have checked that they are suitable for cats.

If you think your cat has eaten something potentially harmful, contact your veterinary practice promptly. Keep the packaging or note the ingredient and approximate amount if you can. Don’t wait for symptoms to appear before seeking advice.

Can cats drink milk?

Many adult cats do not digest lactose well. Cow’s milk can cause digestive upset, including diarrhoea, so it is best not to offer it as a regular drink. Fresh water is the right everyday choice.

“Cat milk” products are not a nutritional necessity either. If you choose to offer one, check the label, give only a small amount and include it as an occasional treat rather than a replacement for water or balanced food.

Are human foods enough to make a balanced cat meal?

No single list of safe ingredients can tell you whether a homemade menu is nutritionally complete. Plain chicken, fish or egg may be acceptable as a small treat, but a diet built mainly from these foods can miss essential nutrients or provide them in unsuitable amounts.

A complete recipe needs to account for the whole diet, including energy, protein, fats, vitamins and minerals. Cats also have particular nutritional requirements, such as the need for taurine in their diet. The right formulation depends on the individual cat and the ingredients used.

If you are considering home-prepared meals, ask your vet for guidance and use a recipe formulated for your cat’s needs. Avoid making substitutions or adding supplements without professional advice: changing one ingredient can alter the nutritional balance.

How to introduce a new food

Make dietary changes gradually, unless your vet advises otherwise. Pawlate’s general transition guidance recommends moving to a new menu over seven to ten days:

• Days 1–3: 25% new food and 75% current food
• Days 4–6: 50% new food and 50% current food
• Days 7–9: 75% new food and 25% current food
• Day 10 onwards: 100% new food, if the transition is going well

This is general guidance, not a schedule for every cat. Some cats may need a slower transition, and a vet may recommend a different approach for medical reasons. If your cat develops vomiting, diarrhoea, refuses food or seems unwell, contact your veterinary practice.

How Pawlate can help with cat meal planning

Working out what to feed a cat involves more than choosing ingredients that seem wholesome. The overall recipe, portion and nutritional balance all matter.

Pawlate is designed to help organise personalised meal plans and shopping lists for cats and dogs. The app describes its nutrition planning as aligned with standards including NRC, FEDIAF and AAFCO. Its legal information also makes clear that it is an informational recipe-planning tool—not a veterinary clinic, diagnostic service or replacement for a prescribed therapeutic diet.

That distinction matters. A planning app can help make meal organisation more convenient, but it cannot assess your cat’s health or replace advice from a vet. Speak to your veterinary practice before making a significant dietary change, particularly if your cat has a health condition or needs a special diet.

A quick checklist for cat owners

Before offering a new food or changing your cat’s meals, ask:

1. Is the food safe for cats and prepared without harmful ingredients?
2. Is it a small treat, rather than a substitute for complete cat food?
3. Does the overall diet meet my cat’s nutritional needs and life stage?
4. Could a health condition or prescribed diet affect what my cat can eat?
5. Have I checked with my vet if I’m unsure?

Knowing what cats can eat makes everyday decisions easier. Keep treats plain and occasional, avoid risky ingredients, and make sure your cat’s main diet is complete and appropriate for their needs.
