My cat is very prone to hairballs, and unfortunatly hairballs can turn into a tramatic and expensive experience. I recently spent most of my savings at the vet trying to remove a hairball from my cat Zasper. I have since switched to Science Diet Hairball formula which works great, and some treats to prevent hairballs. Zasper never really liked being brushed because her skin is so sensitive. I finally found a slicker brush that is plastic coated so it won't hurt her. I've also started giving her baths to loosen most of her hair, however this may not be a possiblity for your cat since most hate water. I may be going a little overboard on hairball treatments for my cat, but I hope to never have to her to the vet again for another $500 hairball!!!
