So if your cat is throwing up partially digested food, it will often be some shade of brown or tan. Brown vomit in cats may be solid, liquid, or somewhere in between.

It's not uncommon for cats to vomit. However, it is important to understand your pet's behavior since the reason for their sickness could be serious.
