While there are many joys that come with owning a cat, one drawback some owners may be familiar with is the occasional discovery of cat vomit. This aspect of cat ownership may spark concern in pet parents, but vomiting in cats can result from a variety of conditions, from benign to harmful.
Dr. Lori Teller, an associate professor in the Texas A&M College of Veterinary Medicine & Biomedical Sciences, says that one common reason a cat may vomit is hairballs. When cats groom themselves, they may swallow loose fur that clumps in their gastrointestinal tract. These clumps eventually become irritating, causing the cat to vomit up the hairball to prevent an obstruction.
