Cat Not Eating or Acting Weak? Understand the Signs of FIP and How to Help | CureFIP 2025

When your cat suddenly stops eating or seems unusually tired, it can be deeply worrying. Cats are good at hiding pain, so when they refuse food, it often means something serious is going on.

Cat Not Eating or Acting Weak? Understand the Signs of FIP and How to Help

Sometimes the reason is simple — stress, a new environment, or a minor upset stomach. But in other cases, it may signal a dangerous illness such as Feline Infectious Peritonitis (FIP).

Understanding the cause early and acting quickly can make all the difference in your cat’s recovery.


Why Cats Stop Eating

1. Stress or Environmental Changes

Cats love routine. Any change — a new pet, moving house, travel, or even loud noise — can make them anxious. This stress can cause appetite loss.What to do: Keep your cat’s space calm and consistent. Offer familiar bedding, soft lighting, and patience.

2. Sudden Change in Food

Cats are sensitive to smell and texture. Switching food brands too fast may cause rejection.What to do: Mix the new food with the old gradually over a week to help your cat adjust.

3. Mouth or Dental Pain

Gum inflammation, tooth decay, or mouth ulcers can make eating painful.What to do: If your cat drools or avoids hard food, schedule a veterinary dental check.

4. Digestive Issues or Infections

Vomiting, diarrhoea, or intestinal infection can cause nausea and loss of appetite.What to do: Keep your cat hydrated and offer easy-to-digest food. If symptoms last more than 24 hours, see a vet immediately.


When a Cat Doesn’t Eat for More Than 24 Hours

If your cat refuses food for more than a day, it’s a red flag. Cats that stop eating for too long are at risk of hepatic lipidosis (fatty liver disease), a life-threatening condition.

Appetite loss, weakness, and fever may also indicate Feline Infectious Peritonitis (FIP), a serious viral disease that needs prompt diagnosis and treatment.


What Is Feline Infectious Peritonitis (FIP)?

FIP develops when a common feline coronavirus mutates inside the cat’s body. This mutation triggers an immune reaction that causes inflammation in organs such as the liver, kidneys, and brain.


As the disease progresses, cats lose appetite, energy, and weight. They may also develop a swollen abdomen or fever that doesn’t respond to antibiotics.

FIP was once considered untreatable. Today, with the antiviral medication GS-441524, recovery is not only possible but increasingly common.


Recognizing the Symptoms of FIP

According to global data from CureFIP, cats suffering from FIP often show:

  • Refusal to eat or loss of appetite

  • Sudden weight loss

  • Persistent fever

  • Swollen abdomen (wet FIP)

  • Dull, cloudy, or yellowish eyes

  • Wobbling or unsteady movement

If your cat displays two or more of these signs, visit your veterinarian immediately for proper testing.


Why Cats with FIP Stop Eating

Cats with FIP often stop eating because:

  • Inflammation affects their digestive system

  • Fever and pain make eating uncomfortable

  • Organ dysfunction leads to nausea

  • Fatigue reduces their energy to eat

This isn’t stubborn behaviour — it’s a physical response to the disease. The earlier treatment begins, the better the chance of recovery.
