Product review (5 stars): Best that I have found
After Petro Malt changed it's formula my cat would not it eat. I tried just about every thing else there was. He would not eat anything out there. He's a long haired, 14 year old cat & he developed  a hairball he had trouble passing. After spending much $$ at vets office I discovered OH NO! HairBall.  My cat loves it & it works.  If you have a long haired cat you have to brush, brush, brush, & even then your cat can get hair balls. But boy has this ever cut back on them.  If he coughs one up, it's just a little one, not a massive one like he use to & now it's 1 a month instead of every other day.
