My cat is taking Phenobarbital for seizures after a flea shampoo. Today I discover that he has tapeworms and this is the 3rd time. The vet told me last time that cats get tapeworms from fleas after they kill them with their mouth. I think the solution is to get rid of the fleas. I donâ€[emoji]8482[/emoji]t know what to do since he gets seizures from a flea shampoo, I donâ€[emoji]8482[/emoji]t know if to use Revolution. I would like to hear from you first before asking the vet?
