Why did my cat die suddenly from liver disease or hepatic lipidosis?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Female | spayed | 8 years and 2 months old | 10 lbs

My cat of 7yrs died suddenly. She lost a lot of weight rapidly, but still had an appetite. After a few days, she looked lethargic, was drinking a lot of water, but still eating a lot. We took her to the vet. I'm not sure why she died so quickly. The vet said she had fat in her liver, high liver enzymes, jaundice, and then she stopped wanting to eat. There might also have been a thyroid condition. So did she die from thyroid or liver problems? I just need some insight. Thanks.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! I am so sorry for the loss of your cat P! Cats are very good at hiding illnesses until they are very sick. Jaundice in cats can be from: 1) destruction of red blood cells. They tend to be anemic on blood work. This can be from blood parasites, cancer, immune problems 2) Liver disease: cancer, infection, toxin, inflammatory conditions or fatty liver disease (hepatic lipidosis). Fatty liver is a secondary condition. Prolonged anorexia is usually the cause. Anything that makes a cat stop eating for more than 3 days can cause fatty liver disease and 3) Gall bladder, biliary or pancreatic disease: infection, cancer, gall stones, biliary obstruction. P didn't die from an overactive thyroid. She died from whatever disease caused her to stop eating, that could have been liver disease or another disease that caused fatty liver syndrome. She sounded like she was very sick. I hope this provides some insight. Again I am sorry for your loss.
