Why Isn’t My Cat Eating or Drinking?

When your cat seems to suddenly lose interest in food or water, you may understandably become quite worried. Dehydration and nutrient deficiencies are serious issues for cats that can develop quickly. At LaPorte Animal Hospital, we are familiar with this concern. Our team is here to help you understand what might be going on and when it’s time to act.

Some of the most common reasons a cat stops eating or drinking include:

• Stress or changes in routine
• Dislike of bowl location or food/water type
• Dental pain or mouth discomfort
• Nausea or digestive upset
• Underlying illness

In this post, we’ll give you a closer look at each of these, so you can learn what behaviors may be normal and when to call a vet.

What Can Cause a Cat to Stop Eating or Drinking?

Stress or Changes in Routine

Cats are creatures of habit. A new pet, a move, a new baby, or even a rearranged piece of furniture can trigger enough anxiety to suppress appetite. Some cats also react to schedule changes, such as a shift in feeding times or an owner’s new work hours. If nothing else has changed health-wise, try restoring your cat’s normal routine as much as possible and giving extra quiet time before reassessing.

Dislike of Bowl Location or Food and Water Type

Cats can be particular. A food bowl placed near a litter box, a loud appliance, or a high-traffic area may simply feel unsafe or unappealing. Similarly, some cats strongly prefer running water and may ignore a standing bowl entirely. You may want to try moving their bowl, trying a different bowl material like metal or ceramic, or slowly introducing new foods or filtered water to see if preference is causing the problem.

Dental Pain or Mouth Discomfort

Mouth pain is one of the most overlooked reasons cats avoid food. A cracked tooth, gum disease, or oral ulcer can make eating genuinely painful. The cat may want to eat but pulls back when it hurts to chew.

Watch for confirmatory signs of dental issues like:

• Dropping food from the mouth
• Pawing at the face
• Bad breath
• Preference for soft/wet food over dry

Nausea or Digestive Upset

A cat experiencing nausea will often eat less or not at all. Causes range from eating something they shouldn’t have to hairballs, motion sickness, or a reaction to medication.

Look for accompanying signs like:

• Drooling
• Lip licking
• Vomiting or retching
• Lethargy

Mild nausea may pass on its own within a day. Persistent symptoms, however, typically warrant a vet visit.

Underlying Illness

Prolonged appetite or water intake changes can point to a more serious health condition. Diseases such as diabetes, kidney disease, pancreatitis, and infections can all affect how a cat eats and drinks.

Cats are known for masking discomfort, which makes early detection of health problems especially important. Annual wellness exams and bloodwork can help catch these issues before they become advanced.

When Should You Seek Veterinary Care for a Cat That Won’t Eat?

You should seek professional care promptly if your cat:

• Has not eaten or had any water for more than 24 hours
• Shows signs of significant lethargy or weakness
• Is vomiting repeatedly
• Has a notably distended or painful abdomen
• Is a kitten or senior cat, or has a known health condition

Cats that go without food for 48 or more hours are at risk of a serious liver condition called hepatic lipidosis, which can develop rapidly and become life-threatening. You should not wait to see if this situation resolves on its own.
