Why fasting can quickly kill your kitty

As you probably know, humans can go for long periods of time only consuming water, but did you know cats can die in as quickly as two days after not eating?  This harsh reality is why it’s extremely important to ensure your fur baby is eating regularly.

While Hepatic Lipidosis (more commonly known as fatty liver disease) has been seen in some toy breed pups, it tends to be more unique to cats.  You’re probably wondering, what is fatty liver disease?  When your kitty begins a period of anorexia/fasting, the body begins moving stored fat to the liver in order to process it for energy.  The fat deposits begin building up in the liver interfering with its normal function, and when left untreated it ultimately leads to death.


Essentially anything that causes your kitty to not eat can ultimately lead to fatty liver disease.  Obese kitties tend to be at higher risk.  Common causes include the following:

  • Pain
  • Nausea
  • Stress
  • Pancreatitis
  • Disease (IBD) and other diseases that cause the body to not properly absorb energy from food

Some of the most common systems to look for are as follows:

  • Reduced appetite / not eating at all
  • Vomiting or drooling, which is often a sign of nausea
  • Hiding / disinterest in normal activities
  • Lethargy
  • Jaundice (yellowing of the white portion of the eyes, ears, gums, or skin)
  • Dehydration
  • Constipation
  • Weight loss / muscle wasting

Your veterinarian will take into account the medical history you provide and will perform blood tests to look for abnormal values.  An ultrasound will likely be recommended to take a look at the liver, and additional tests may be needed to rule out other diseases.


If your kitty reaches the point of diagnosis with fatty liver disease, you can expect for your veterinarian to admit your fur baby for around the clock care.  Your vet will attempt to treat the underlying cause of not eating, which may include administering anti-nausea meds, appetite stimulants, and antibiotics if an infection is suspected.  Your kitty will also be given IV fluids to address dehydration.  If medications aren’t getting your kitty to eat on his/her own, your vet may recommend a surgical procedure to place a feeding tube.  This tube will allow calories to be provided until your kitty is willing to eat again.

Has your kitty ever gone for an extended period of not eating?
