If your cat has stopped eating, it should always be taken seriously. Loss of appetite in cats is one of the most common early signs of illness we evaluate at Huntington Beach Pet Hospital, and in many cases it is the first indication that something more serious is developing.

If your cat is not eating and you’re unsure what to do, call Huntington Beach Pet Hospital at (714) 962-3639 so we can help guide you on the next step.

At Huntington Beach Pet Hospital, we provide same-day veterinary evaluations in Huntington Beach for cats who have stopped eating, especially when symptoms have lasted more than 24 hours.

In general, if your cat has not eaten for 24 hours or more, it’s best to have them evaluated.

When It’s Urgent

Bring your cat in promptly if you notice:

  • Not eating for more than 24–36 hours
  • Lethargy or hiding
  • Vomiting or weight loss
  • Drooling or signs of mouth pain
  • Rapid breathing or weakness
  • Intermittent diarrhea

Cats tend to hide illness well, so loss of appetite is often one of the earliest warning signs.

If your cat has stopped eating or is showing any of these symptoms, call Huntington Beach Pet Hospital at (714) 962-3639. We can help determine how urgent the situation is.

Common Causes of Loss of Appetite in Cats

Loss of appetite in cats can be caused by a variety of conditions, including:

  • Dental disease or oral pain
  • Gastrointestinal illness
  • Kidney disease
  • Liver disease
  • Stress or environmental changes
  • Infections

In many cases, multiple factors are involved, and the underlying cause cannot be determined without an exam.

Why You Should Not Wait Too Long

Cats are different from dogs. When they stop eating, they are at risk of developing hepatic lipidosis (fatty liver disease), which can become serious quickly.

What happens is that when cats stop eating, their bodies begin to break down fat for energy—but that fat accumulates in the liver instead of being processed normally, leading to worsening illness.

Many cats initially show only decreased appetite before developing more serious symptoms, including vomiting or lethargy, which is why early evaluation is so important.

If your cat is not eating and symptoms are not improving, call Huntington Beach Pet Hospital at (714) 962-3639 so we can help determine the next step.

Early intervention significantly improves outcomes.

What to Do If Your Cat Is Not Eating at Home

Short-term monitoring may be reasonable if:

  • Your cat missed only one meal
  • Is otherwise acting normal
  • Has no vomiting or other symptoms

Dr. Lewis also recommends gently feeling your cat’s abdomen. If it feels painful, tense, or unusually firm, this may indicate the need for more immediate veterinary evaluation.

However, if appetite does not return quickly, your cat should be seen. If you’re unsure what to do, it’s always safer to call—many serious conditions can begin with mild symptoms.

When to See a Vet for a Cat Not Eating

You should bring your cat in for evaluation if:

  • Your cat has not eaten for more than 24 hours
  • Vomiting is present
  • Symptoms worsen
  • Behavior changes or lethargy develops

At Huntington Beach Pet Hospital, we often find that early evaluation helps prevent more serious complications.

What We Do at the Hospital

When evaluating a cat that is not eating, we typically:

  • Perform a physical exam
  • Check for dental or oral pain
  • Assess hydration and weight
  • Recommend diagnostics if needed (bloodwork, imaging)

In many cases, subtle findings on exam can help guide diagnosis even before testing is performed.

Treatment depends on the cause but may include fluids, medications, and nutritional support.

FAQ

How long can a cat go without eating?
Cats should not go more than 24–48 hours without food.

Is it normal for cats to skip meals?
Occasionally, but a persistent loss of appetite is not normal. It is also important to watch trends. If your cat typically eats well but suddenly eats significantly less, this is an important change that should be evaluated.
