This guide will help you to take care of your cat properly and feed them in time as well.

Let’s get started:

Not too long ago, a fellow fur parent decided to change the cat food into another brand.

​It became the group’s topic of discussion especially when the cat owner revealed her cat had been ignoring the food she replaced the old one with.

​Who knows how long the cat has been ignoring it and how long it has been hungry.

It is not only in situations like this when a cat goes hungry. There are times when the cat just doesn’t follow your lead and refuse any food you give them. Leaving you all worried whether they’d survive another day without eating.

How Long Can A Cat Go Hungry​?

How long can a cat survive without eating or drinking? The normal range of days with no food or water for cats may run from 24 hours to 48 hours.

Yet, not all fat cats that starve for a long time will develop HL. At an HL suspicion, the vets will measure the liver enzymes which would possibly be increased considering the disease, notwithstanding the cat’s body built.

Clinics will use radiographs and ultrasound imaging to rule out other diseases associated with secondary HL. However, the most accurate way to be certain about HL is to do a liver biopsy. Performed under anesthesia, the patient must stay overnight for monitoring to avoid further complications.

Worrying About A Cat Refusing Food

​Cats have a distinctive ability to hide illness or underlying disease. This leaves cat owners less time to work on the problem especially if it has progressed unnoticed. A change in appetite is usually the biggest indicator of a cat’s health condition.

​Generally, a feline can last a good week without food. However, for some of them, their survival rate may only be as long as three to four days.

​This is due to their livers that are not made to support their bodies for long, surviving only from the body’s stored energy.

​What Happens If A Cat Goes Hungry For A Long Time

It can be hard to tell when to visit the doctor to know what’s going on when the cat refuses to eat.

​However, you should always bear in mind that keeping them hungry for long periods can do more harm than what could already be happening within their bodies.

It is dangerous for a moggy to stay starving for a long time. This is because, aside from any disease they may be suffering from, driving them not to eat, being hungry leads to them getting a hepatic lipidosis – or more commonly known as fatty liver disease.

Fatty liver disease is the most common malady in cats. It happens when there is an extreme build-up of fat inside the cells and tissues of the liver. If disregarded, it may progress and lead to liver and biliary tract dysfunction and death.

But, how does being hungry relate to fatty liver?

When a kitten goes for too long without eating, the fat cells stored in the body are processed and broken down for energy.

​This is the typical and common response to starvation for most animals. The fat being metabolized is packaged with protein and sent through the bloodstream to the cells of the body.

However, if the animal is not eating, there won’t be enough protein to go along with the fat.

​Therefore, the fat builds up in the liver and upsets the function of the liver. The liver dysfunction it results in will even make the cat less likely to want to eat, then becomes even sicker.

Hepatic lipidosis has two types:

Idiopathic HL is when the cats stop eating for no apparent reason. This is usually triggered by stress led by the change of diet, moving to a new environment, a new member in the household, or even the death of a companion. Cats are habitual so any changes in their environment cause extreme stress.

Secondary HL happens as a result of preexisting ailment or health conditions like diabetes, gastrointestinal disease, pancreatitis, or cholangiohepatitis.

​Such diseases change the cat’s appetite leading to anorexia, and further developing HL.
