The cat does not eat: when to go to the vet right away?

📍 Veterinary Hospital Sacrum, Vantaa — Emergency service: 010 739 9130

In the case of cats, the saying “yes they eat when they get hungry” is a dangerous myth. Unlike dogs, a cat does not tolerate fasting well. If the cat does not eat, this is often a serious illness or pain condition, and prolonged failure to eat can lead to life-threatening liver damage.

Why is not eating dangerous for a cat?

When a cat stops eating, its body starts burning fat stores for energy. However, the cat's liver cannot process large amounts of fat, so fat begins to accumulate in the liver cells.

This state is called liver syndrome (hepatic lipidosis). It can develop in as little as a few days and, without treatment, lead to death. Therefore, a cat's lack of food needs to be reacted quickly.

When to go to the vet on call?

Contact us Veterinary hospital Sacrum for emergency care in Vantaa, if:

1. The cat hasn't eaten in 24 hours

This is the absolute limit for an adult cat. In puppies, the limit is significantly shorter (a few hours).

2. The cat hides or is apathetic

A cat is a master at masking pain. If a cat withdraws to its own conditions, does not come to be greeted, or sleeps exceptionally much, it is likely to be sick.

3. The cat vomits repeatedly

Indigestion combined with vomiting quickly dehydrates the cat. The cause may be a foreign object (eg wire), kidney failure or pancreatitis.

4. The cat visits the sandbox, but nothing comes

Especially in male cats, urinary tract obstruction is a life-threatening emergency. It may seem that the cat is “just” uneaten and restless.

What do you do at the vet?

In the emergency room, we will investigate the cause of not eating (blood tests, X-ray, ultrasound) and, if necessary, initiate hydration and force-feeding or tubing to prevent liver damage.

Don't stand by — not eating a cat is always an alarm sign.
