The cornea is the clear, glistening membrane that makes up the surface of the eyeball. A penetration or erosion through a few layers of the outermost corneal epithelium is called a corneal erosion or corneal abrasion. A corneal ulcer is a deeper erosion through the entire epithelium down into the stroma.
Hepatic lipidosis, also known as fatty liver syndrome, is unique to cats and is one of the most common liver diseases seen in cats. Usually a cat with hepatic lipidosis has recently gone through a period of anorexia. When fat is broken down rapidly to supply energy and nutrients to the anorectic cat, it can overwhelm the ability of the liver to process and the fat becomes stored in and around the liver cells, further compromising liver function. Diagnosis of hepatic lipidosis is made from blood tests that demonstrate poor liver function and from a liver biopsy or aspirate. This disease is treatable with aggressive nutritional support until a normal appetite returns.
Many think that because cats are finicky eaters they are poisoned less often than dogs. However, with their curiosity and fastidious grooming, intoxication is, unfortunately, not uncommon. Several factors predispose cats to becoming ill once they have been exposed to even a small amount of a poisonous substance.
