NATIONAL HAIRBALL AWARENESS DAYOn the last Friday in April, National Hairball Awareness Day this day is founded by Dr. Blake Hawley of Hill’s Pet Nutrition out of Topeka, Kansas . He draws attention to a problem many cat lovers face.The formation of hairballs is a common feline condition that is brought on by self-grooming and the associated ingestion of hair. Cats pass the hair through their digestive track or will vomit the hairball. If they don’t eliminate the hairball from their digestive track one way or the other, hairballs can create an obstruction. Obstructions can cause serious medical issues for a cat.so finally this day is related on cat hairs and must care about cat Health .
