Cat Not Eating

Cat Not Eating: Causes, When to Worry, and When to Seek Care

A decreased appetite—or not eating at all—is often one of the first signs that something may be wrong with your cat. While some cats may occasionally skip a meal, ongoing or sudden refusal to eat should always be taken seriously.

Cats are especially sensitive to not eating, and prolonged lack of food intake can quickly lead to more serious health complications. Because of this, it’s important to monitor any changes closely.

Common Causes of Loss of Appetite in Cats

There are many reasons why a cat may stop eating, ranging from mild issues to more serious conditions. Common causes include:

  • Gastrointestinal upset (vomiting, diarrhea, nausea)
  • Stress or environmental changes
  • Dietary changes or food aversion
  • Dental disease or oral pain
  • Infections
  • Fever
  • Toxin ingestion
  • Kidney disease
  • Liver disease
  • Pancreatitis

In some cases, loss of appetite may be the only noticeable symptom early on.

When Should You Be Concerned?

Cats should not go long without eating, and certain signs indicate your cat should be evaluated by a veterinarian.

You should seek care if your cat:

  • Has not eaten for more than 24 hours
  • Is also vomiting or has diarrhea
  • Appears lethargic or weak
  • Has weight loss or ongoing decreased appetite
  • Is drooling or having difficulty chewing
  • Is hiding or showing behavior changes
  • Is a kitten, senior cat, or has underlying health conditions

If your cat goes more than a day without eating, prompt care is strongly recommended.

How We Diagnose Loss of Appetite in Cats

At L&L Animal Urgent Care, we focus on identifying the underlying reason your cat is not eating.

Diagnostics may include:

  • Physical examination and history review
  • Bloodwork to assess organ function and check for infection
  • X-rays to evaluate for internal abnormalities
  • AFAST/TFAST ultrasound scan if needed
  • Additional testing based on symptoms

Our goal is to determine whether the issue is mild or requires more advanced care.

Treatment Options

Treatment depends on the underlying cause of your cat’s decreased appetite.

Common treatments may include:

  • Anti-nausea medications
  • Fluid therapy to address dehydration
  • Pain management
  • Appetite stimulants in select cases
  • Treatment of underlying infections or conditions
  • Dietary support and recommendations

More serious cases may require hospitalization and supportive care.
