How much or little your pet eats can often indicate how they feel. Therefore, it is essential to notice when they are not eating much, even if they appear normal. Fortunately, we have designed a handy article to guide you through the process from start to finish. Remember, your cat cannot talk to you like another human would. They cannot explicitly tell you when something is wrong. Therefore, you must learn to understand the little differences in their behavior and how to react to them.

How to tell that Cat is not eating much?

Appetite problems may not be completely obvious initially, especially when your cat is acting normal in their day-to-day lives. This is especially the case if you have multiple cats in your house or if you free feed. Just because the food bowl is empty does not mean that one cat is not experiencing a reduced appetite. The things you should be on the lookout for are:

  • The cat is not eating as much as usual;
  • The weight has dropped;
  • It does not seem as enthusiastic when faced with treats;
  • Rejects food.

Why is my Cat acting normal but not eating much?

1. Your cat is not hungry

Sometimes it can be as easy as it is, just not hungry. This often results from overfeeding, meaning you put so much food down for them that they do not need it all. The usual rule of thumb is to provide between 24 and 35 calories per pound for your cat each day. If you notice your kitty leaving behind substantial portions, you should consider reducing portions.

To be safe, you should book an appointment with your vet to rule out any psychological or physical illness. Try to reduce the portion sizes to the recommended amounts and see if your cat continues to eat. If the volume appears okay, they may not like the food you are providing.

2. Does not like the food

This is often the easiest-explained reason for not eating. After all, we all find it difficult to chow down on foods we do not like. Cats are no different. Some cats are simple eaters and consume anything you put in front of them. However, others will be picky about what they eat, making them tricky to buy. Believe it or not, some would rather starve than eat something they do not enjoy. Therefore, finding your cat’s favorite grub can be an adventure of trial and error. Purchase a load of different options, wet and dry, observing what they seem to like and don’t. The clues come in the form of how much they eat, how quickly, and whether they leave any behind.

While this isn’t true for all cats, many of them prefer to eat wet food because it’s closer in consistency to their natural diet. If your cat is refusing to eat dry food, consider looking at these wet cat food options at Veterinarians and choose one that’s best for your feline friend.

Cats are also known to resist changes in diet from time to time. For example, you may switch up your pet’s diet to make them healthier long-term or because you think they’ll appreciate the variety. However, the opposite may, in fact, be true.

You can do several things to ensure that your cat is more satisfied with their daily meals. When changing their diet, one helpful tactic can be to change gradually. That means mixing some of the new diet food into their usual meals and slowly increasing the quantity over time until they are eventually left with the fresh food alone. Food should always be served warm or, at the very least, at room temperature. Cats are known to be fussy about the temperature of their food. It would help if you never lost your temper or refused to put food down for a cat that isn’t eating much. Be patient and persistent with them through the process. If your feline is starving and you are seriously worried about its health, feed it some of its favorite foods to get it back on track. As we said before, you can then make the changes slowly from here. In terms of food quantity, you should aim to provide your cat with 24-35 calories per pound daily.

3. Your kitty is sick and may have medical problems

We all get sick occasionally, and your cat is no different. Illness can often affect your cat’s appetite, meaning that a sudden reduction in food consumption can indicate something is wrong inside. Common problems can include:

  • Stomach upset – When eating causes stomach pain or discomfort, they often decrease the amount consumed or stop eating altogether to avoid the discomfort. This can also often go hand-in-hand with vomiting and diarrhea. 
  • Pain – Some cats refuse to eat because the process of eating in itself is causing them pain. They may also stop drinking water for the same reasons. This could be due to problems with their spine, jaw, posture, throat, and more.
  • Dental problems – If a cat is suffering from dental problems then eating may be uncomfortable, especially hard foods. The most common tooth problems in cats are periodontitis, gingivitis, and tooth resorption. 
  • Indigestion – If the cat is experiencing discomfort within their digestion system, they will often opt to avoid eating altogether. 
  • Senior problems;
  • Cancer;
  • Gastrointestinal issues;
  • Pancreatitis;
  • Kidney problems, like CKD; [1]
  • Infection.

Once you notice that your cat has not customarily been eating for an extended period, you should book a vet appointment as early as possible. The vet will be able to conduct an exam and diagnostic tests that will help pinpoint the cause of the problem. At the very least, they will be able to rule out medical causes that will lead to looking at the food quality or quantity as the reason they’re not eating. 

4. Your cat was recently vaccinated

If your cat has recently had any form of vaccination or other injection, it may explain a sudden loss of appetite. The good news is that this is entirely normal and common in cats. Vaccinations and injections are necessary to ensure your pet remains fit and healthy. However, they can sometimes reduce appetite for a couple of days. It would help if you looked to entice your feline friend with some of their favorite food during these few days. If the issue persists beyond the three-day mark, you may need to visit the vet.

5. Psychological stress and behavioral problems

Animals can go through periods of psychological distress for various reasons. These issues can be linked to anxiety, depression, stress, and fear. This can stem from a change in the cat’s surroundings, new people, new pets, additions to the family, new objects, a change in the day-to-day routine, and much more. Essentially, any change that the cat is not used to can, in theory, result in some form of psychological stress. Some cats can deal with these periods of stress on their own without any impact on their diet, while others will suffer from a drop in appetite.[3]

Care, patience, and time are key ingredients when dealing with psychological problems in your cat. It would help if you first took your cat to the vet to ensure that psychological issues cause their reduced appetite. The vet will take a look at your feline friend and look to rule out physical problems. Once you are sure that the issues are psychological, you can start to work towards a solution. Try to make them feel as comfortable as possible, spend time with them, get them acclimatized to any changes, and help them through this tough time.

6. Your cat does not like travel 

This links to the previous section on psychological stress but is definitely worth mentioning in its own breath. If you have recently moved homes or are traveling with your cat on board, you may notice a drop in their appetite. This is because changes in routine and new surroundings can cause stress in your feline friend, making them less inclined to eat. Cats can also experience motion or travel sickness in cars/trains/planes, and they often need time to adjust to the new surroundings or for the sickness to wear off. Looking into motion sickness medication for next time is also a good idea.

How to encourage your Cat to Eat?

Like most animals, cats only stop eating when there is some kind of problem. Therefore, more often than not, in order to encourage them to eat again, the problem must first be solved.

Whether it is easing your cat’s pain, finding food they prefer, or adjusting the quantity, it is up to you to fix the issue.

Here are a few ways to encourage your feline to eat more:

  • Top your cat’s food with their favorite food or treat.
  • Heat up a little food before giving it.
  • Mashup your cat’s food, especially if your kitty experience hard times chewing or swallowing their food.
  • Similar to the previous step you can also add some broth to their food. Don’t forget it should be salt-free.[2]

Why is my cat drinking a lot of water but not eating?
