Every cat is different when it comes to their eating habits. Some might lick their bowls clean while others leave some food behind. This can be normal for some cats but it could also indicate a behavioral or medical problem in others. If your cat never finishes their food, read on to find out the possible reasons why.
Most cats prefer to eat smaller, more frequent meals throughout the day rather than one or two large meals. If your cat doesn't finish all their food, try spreading meals out, using wide, shallow bowls, and feeding them in a quiet area. If it’s a sudden change, visit your veterinarian to rule out medical issues that could be causing your cat not to finish their meals.

Feline Eating Habits
Cats eat differently than dogs and other household pets. Cats are grazers and often prefer to eat little and often rather than eating one or two big meals a day. This is because in the wild they would have eaten several small prey animals a day. A cat’s stomach is adjusted to eating small amounts at a time, and domestic cats have inherited this trait, too.
Although some cats might be the exception and eat large portions in one go, most cats prefer to graze. If the food is particularly tasty or treat they might eat more than they usually would. In general feeding your cat small portions throughout the day is ideal.
Cat owners can feed wet food in small portions and leave out a bowl of dry food to allow cats to graze. This is a good option as long as your cat isn’t overweight and likely to gorge on the bowl of dry food.
Wanting to eat smaller portions more frequently throughout the day might explain why your cat is leaving food behind in their bowl, but there are other reasons, too. We’ll discuss these now.
Why Do Cats Never Finish Their Food?
It can be worrying when you see that your cat isn’t finishing their food. Do they like their food? Are they unwell? There are many reasons why a cat doesn’t finish their food; some are harmless and others are more serious reasons. We’ll discuss the causes of this now.
1. Meals Are Too Big
As we’ve mentioned above, cats like to eat little and often. If you’re feeding your cat one or two large portions a day it might be too much for their stomachs. This might explain why your cat isn’t finishing their food and leaves some behind in their bowl. They might not be able to eat large portions of food all at once.
2. Disliking the Food
Another reason to explain why your cat never finishes their food is that they simply don’t like the food. They might have been eating the food type for a while or it could be a new food.
New foods need to be introduced very slowly (over the course of one to two weeks) to encourage cats to accept it. Cats are very particularly eaters and might not eat the food if it’s been introduced quickly.
A common reason for cats not eating their food is simply that they’re being fed too much. Regardless of whether cats are fed one to two times daily or frequently throughout the day, if the portions are too big they won’t finish the food.
Cats’ stomachs aren’t adapted to eating large amounts of food and they prefer to eat little and often. Having said that, some cats will overeat and finish large portions of food. This isn’t good for cats as overfeeding can lead to obesity. Obesity causes many health problems for our cats including diabetes and mobility issues.
4. Problem With the Food Bowl
If cats don’t like their food bowl, they aren’t likely to spend too much time eating from them. It may cause them to stop eating and leave some food behind. Cats like food bowls that are wide and shallow. This allows them to eat without their sensitive whiskers hitting the sides of the bowl and it also allows them to watch their surroundings while they eat. Some cats prefer ceramic or glass bowls instead of steel as this is reflective.
5. Noisy Environment
The type of food bowl that cats eat from is very important to encourage cats to eat, but the location of this bowl is equally important. Food bowls need to be positioned in quiet areas of the house with low traffic.
They should ideally be away from other pets such as dogs and out of reach of young children. If the food bowls are in areas of the house that are very noisy and busy, cats might be too nervous or uncomfortable to eat their food. This might cause cats to eat less food and leave food behind in their bowls.
6. Eating Elsewhere
If your cat has outdoor access and isn’t eating all of the food you give them, they might be getting fed elsewhere. It’s common for cats with outdoor access to visit different houses and eat treats or scraps that are offered to them. It’s also common for outdoor cats to have multiple different owners without the other owners knowing!
7. Eating Too Many Treats
If we eat too many treats before our dinner, it’s likely that we won’t eat all of it. This is the same for cats. If cats are eating lots of treats and table scraps throughout the day, they might be too full to eat their dinner.
Although treats and human food scraps are small, they can account for a lot of calories and build up throughout the day. Giving too many treats can also lead to overfeeding and obesity if it’s not being monitored.
8. Medical Issues
If your cat isn’t finishing their food, there could be a medical issue causing it. Health issues such as dental disease, inflammatory bowel disease, hairballs, urinary tract disease, chronic kidney disease and many more can all cause reduced appetites (or loss of appetite), which can lead to food being left in the bowl.

What To Do if Your Cat Doesn’t Finish Their Food
If your cat isn’t finishing their food, it’s best to rule out medical issues as a cause. This is particularly important if it’s a new problem as your cat could be unwell. Your vet will examine your cat and check for any abnormalities. They might recommend further testing if they’re concerned.
Once medical issues have been ruled out, you can focus on other causes. Ensure that your cat has a wide, shallow ceramic or glass food bowl and that it’s in a quiet, low traffic area of the house.
If you’re introducing a new food (wet food or dry kibble) to your cat’s diet, do this slowly over the course of one to two weeks by slowly increasing the amount of new food and reducing the amount of the old food. Feed your cat a high quality, complete food to keep your cat’s health optimum.
Cats are natural grazers and they prefer to eat little and often. It might be normal for them to leave food behind if they’re being fed one to two times a day and if the portions are large. If your cat isn’t eating all of their food, visit your vet to rule out medical issues as cause first.
Ensure that your cat has a wide, shallow food bowl made from ceramic or glass and that it’s in a quiet part of the house. Feed them little and often to mimic how they would have eaten in the wild.

Frequently Asked Questions
How do I get my cat to finish all the food?
Cats prefer to eat little and often. You can offer smaller portions of food more regularly throughout the day to encourage them to eat more if you’re concerned about their weight. Cats will often leave food behind if the portions are too big at one time as their stomachs are adjusted to eating small amounts at one time.
Why does my cat not eat all his wet food?
Offering too much food or a recent change in diet can cause cats to leave food behind. Make any new food changes slowly over one to two weeks. Visit your vet if your cat is suddenly eating less food.
Why does my cat only eat half of his food?
It might be that you’re feeding too much at one time—cats prefer to eat little and often. If it’s a sudden change, visit your veterinarian to rule out medical issues that could be causing your cat to eat less (e.g., dental disease or chronic kidney disease).
Will cats starve themselves if they don't like the cat food?
Yes cats will starve themselves if they don’t like the food. This can cause medical issues such as fatty liver disease or dehydration. Make any new food changes very slowly over one to two weeks by slowly increasing the new food and decreasing the old food. Don’t force your cat to eat food that they don’t like.
