I'm surprised i haven't written this review already. This salmon flavored paste helps keep my long haired cat from getting hairballs. I just give him about an inch of paste on a spoon and let him lick it or mix it in with his dry food. He goes wild for it and it pulls the hair out of his throat. The tube holds 3 ounces and is sold for around $5 USD in most mass merchandisers (Target, Walmart, Kmart, etc). It's a pretty good investment considering that grooming can only go so far to prevent hairballs.
