Chances are you’ve come across a hairball or two when treating cats. It’s possible you’ve had to surgically remove a hairball from one of them. Par for the course, right? But when the cat is a 450-pound African lion and the hairball is 3.8 pounds, it’s probably a little different. The lion, named Arthur, resides at the Wild Animal Sanctuary in Keenesburg, Colorado, but had to be taken to Colorado State University’s veterinary teaching hospital on Tuesday to have a hairball removed from his stomach. #ColoradoState vets removed a 3.8 lb. hairball from the stomach of Arthur, a 450-pound African lion, yesterday pic.twitter.com/pR9GVI8775 — CSU Vet Hospital (@CSUVetHospital) October 21, 2015 “Lions normally expel hairballs, just like house cats, so this was a rare problem,” staff at the veterinary teaching hospital told ABC7. Arthur is recovering back at the sanctuary.
