If your cat won’t eat, you’ll need to find out why. Here are some common reasons why cats aren’t eating, along with some advice on how to cheer up your feline family member.

Why isn’t my cat eating?

There are many different reasons why your cat may have a loss of appetite, and if your cat isn’t eating a physical exam may reveal the cause, but blood tests and/or imaging tests such as x-rays or ultrasound may be necessary.

If your cat has a decreased appetite or doesn’t eat for more than a day or two, take him to the vet to find out the cause.

This is considered a medical emergency, and not getting enough nutrition can have a number of serious consequences for your cat.

Here are some possible reasons why your cat might not be eating:

1. Your cat may be sick

Upper respiratory tract infections can cause loss of appetite in cats.

2. Your cat may have dental problems

Similarly, many oral diseases can cause cats to stop eating altogether.

Cats can develop painful plaque, gingivitis, and inflammation of other tissues in the mouth, and can also develop cancerous tumors in the mouth.

There are a number of gastrointestinal issues that can cause your cat to lose their appetite, including:

Nausea can also be caused by diabetes or kidney disease (both of which can cause vomiting and changes in thirst and urination) and medications (such as antibiotics and chemotherapy).

4. Your cat may have congestive heart failure

Congestive heart failure can cause coughing, fatigue and difficulty breathing, both of which can decrease a cat’s interest in eating.

Additionally, medications prescribed for heart disease or new foods can affect your cat’s appetite, especially if the new foods have a different taste or texture to what your cat is used to.

5. Your cat may be recovering from an illness or hospitalization.

Some cats may develop a food aversion after being sick or hospitalized – they may associate certain foods with the stress of being sick or hospitalized and refuse to eat them.

If food aversions occur, it may take some ingenuity and trial and error to figure out what your cat will eat.

These changes include:

  • Construction inside and outside the house

  • New smells and odors

Why is my kitten not eating?

Kittens are usually Kittens are weaned onto solid food between 6 and 8 weeks of age. Here are some reasons why your kitten may not be eating:

As you start to transition to solid foods, your kitten needs to be exposed to different types and textures of food and learn to like them. If your weaned kitten isn’t eating, the solution may be as simple as changing their dry food or softening their food by adding liquid.

Offer wet and dry food in a variety of textures and shapes (pâté, stew, soup, triangular dry food, round dry food, etc.) You can also make the food more appetizing to help the transition go smoothly, as a cat’s appetite is heavily influenced by its sense of smell.

Always feed your kitten wet food at room temperature or slightly warmer – warming the wet food will enhance its flavour and make it more appealing to your kitten.

Upper respiratory tract infections are not uncommon in kittens and can cause nasal congestion, fever, and loss of appetite due to fatigue. As with adult cats, contact your vet if your kitten is sneezing or has runny eyes or nose.

A kitten’s natural curiosity can sometimes get them into trouble. Kittens have been known to eat string, glitter, hair ties, and other objects that can become lodged in their stomach or small intestine – a serious medical emergency.

Don’t allow your kitten to play with any objects that could be edible – surgery may be required to remove the object, so contact your vet immediately if you suspect your kitten has eaten an object or if their loss of appetite is accompanied by vomiting.

4. Your kitten may be intimidated by other pets

While many kittens are outgoing and energetic, some shy kittens may be intimidated by other furry family members while eating, so make sure your kitten has a safe place to eat where they won’t be chased or disturbed by other cats or dogs in the household.

If your kitten won’t eat for more than a day, contact your vet to schedule an appointment – the sooner you can identify the cause, the sooner your kitten will return to normal.
