I need help with hairballs too. My cat, Fred has had hairballs all his life. We have took him to the vet before, and we got him some medicine. His hairballs stopped for a while, but lately they have been worse. In the last 2 days he has thrown up about 6-7 times. We bought him some Purina Hairball remedy, but it didn't work. Does anyone else's cat have that bad of hairballs?
