Cat Information Articles

A Trichobezoar, more commonly known as a hairball, is a clump of undigested hair that is sometimes spit up by cats.  Typically, the hairball is damp due to digestive fluids that it absorbs, and is usually shaped like a cylinder, as opposed to a ball – as the name hairball would imply.  Hairballs are typically around an inch in length but can be bigger or smaller and usually match the color of your cat’s fur.
