Feline Hepatic Lipidosis is a fairly common liver disease in cats. Most cats with feline hepatic lipidosis are overweight cats, most often older, who has had a reduction in their caloric intake. Going through a stressful period with inappetance, or not eating while the cat has a cold can be enough for a cat to
acquire feline hepatic lipidosis.

Lipidosis is not quite understood, but one of the charachteristics is of fat globules in the liver cells.

Hepatic lipidosis can be characterized as either idiopathic or secondary to other diseases such as inflammatory bowel disease, pancreatitis, cholangiohepatitis, diabetes mellitus, hyperthyroidism, renal disease, and neoplasia.

Diagnosis is made by blood tests showing elevated liver function tests, liver biopsy showing fat globules within the cells,

Early diagnosis is of the essence. Diagnosed at the early stages, feline hepatic lipidosis can be reversed simply by ensuring sufficient intake of a balanced diet.
In later stages the diease may prove to be fatal.

Ensuring your cat is not overweight, and if she is, reducing the weight in a slow but steady fashion, along with keeping on top of your cats eating habits can go a long way to prevent feline hepatic lipidosis. 

Any cat not eating, even when for an understandable reason such as the cat having a cold, is cause for alarm. If your cat is not eating she needs to be seen by a vet as soon as possible.

If your cat has a cold and does not smell the food, thus not getting much of an appetite, you will have to make her food as palatable as possible. Another option is syringe feeding food which is very nutrient dense. Ask your veterinarian for advice.
