You fill the bowl. Your cat eats. Everything is fine, right? Not always. Many loving owners make small cat feeding mistakes every day, and most of them are easy to fix once you know about them.
In this guide you will find the 10 most common cat feeding mistakes to avoid, why each one matters, and a simple fix you can try today.
Quick Answer: What Are the Most Common Cat Feeding Mistakes?
The biggest ones are guessing portions, giving too many treats and scraps, using a food that is not “complete”, and changing food too fast. Weigh meals, pick a complete food, and switch foods slowly over about two weeks, as PDSA advises.

Mistakes 1-5: The Bowl Habits That Quietly Add Up
1. Scooping by eye. A “heaped scoop” can easily be more than your cat needs. PDSA advises weighing portions to prevent overeating. Fix it with a scale. Shop a digital food scale.
2. Handing out too many treats. Treats add calories fast. PDSA says they should be no more than 10-15% of daily calories, with the main meal reduced to match. See our list of healthy cat treats.
3. Sharing your plate. Table scraps unbalance the diet and can lead to weight gain. PDSA also lists cow’s milk, grapes, raisins, garlic, onions and chives as foods to avoid. If your cat eats any of them, call your vet.
4. Choosing food that is not “complete”. PDSA says food labelled “complementary” is only for occasional treats. Pick a complete food. Browse complete cat food. Not sure what to look for? Read how to choose the best cat food.
5. Switching food overnight. A sudden change can upset your cat’s stomach. PDSA suggests adding a teaspoon of the new food on a separate plate for the first days, then increasing it slowly. Most cats need about two weeks, and some need longer.
Mistakes 6-10: The Hidden Habits Most Owners Never Question
6. Putting water next to food. PDSA says to keep food and water apart, and away from the litter tray. Battersea suggests a second water bowl in a quieter spot, and cleaning food bowls daily. Choose ceramic or metal over plastic. See ceramic cat bowls.
7. Forgetting about extra water. Wet food can increase water intake, says PDSA. Our guide to wet vs dry cat food helps you choose, and our tips on cat hydration show how to get more water into your cat.
8. Using the wrong life-stage food. Kittens, adults and seniors need different things. PDSA recommends kitten-specific food for the first year. See our guides to kitten food and senior cat nutrition.
9. Going home-made or vegetarian without your vet. PDSA says vets advise commercial cat food over home-made, because balancing nutrients at home is very hard. Vegetarian or vegan diets are very difficult to get right.
10. Missing the signs in a senior cat. PDSA says changes in how much an older cat eats and drinks can signal kidney disease, dental problems or diabetes. If your cat eats less, or drinks more, call your vet.

When a Feeding Problem Is Really a Health Problem
Sometimes the bowl is not the issue. Call your vet if your cat:
- refuses food after a slow switch, even when you restart the process
- eats much less, or much more, than usual
- drinks more than normal
- has vomiting or diarrhoea that does not settle
- gains or loses weight without a clear reason
PDSA also says to never change a cat’s food suddenly unless your vet advises it, for example when a prescription diet is needed. If your cat has a food reaction, our guide to cat food allergies covers the warning signs. If weight is the worry, read how to help an overweight cat lose weight safely.
Quick Questions About Cat Feeding Mistakes
How often should I feed my cat? Cats graze, eating 8 to 16 times a day, according to PDSA. Many owners use two measured meals a day. Kittens and older cats do better with smaller, more frequent meals.
Is wet or dry food better? PDSA says either works, or a mix, unless your vet says otherwise. Wet food can increase water intake.
How long should I take to switch my cat’s food? About two weeks, keeping old and new food on separate plates at first. Some cats need longer.
Can I feed my cat chicken? Plain cooked chicken can be a small treat, but it should not replace a complete food. Keep treats within 10-15% of daily calories.
Can cats drink milk? It is best to avoid it. PDSA lists cow’s milk as a food to avoid, and Battersea says never give your cat milk.
