Did you know today is National Hairball Awareness Day?? It's always the last Friday in April.
Hairballs are a common condition in cats caused by self-grooming and swallowing the hair. The hairball will either pass through the digestive track or a cat will vomit the hairball.
If the hairball is not eliminated from the cat's digestive track one way it can create an obstruction and cause serious medical issues.
Regular grooming and a healthy diet can reduce shedding and minimize the amount of hair ingested.
