So I just found out that my local vet will stop prescribing/selling Revolution which is what my cat currently uses. They'll be replacing that with Bravecto, a flea med I've never really heard of. A couple of Google searches later, I found super mixed reviews where dogs/cats vomited and nearly died. The reviews made me think of Cheristin which is a med I used only once for my cat and he acted negatively to. Is there anyone knowledge about this brand and perhaps can tell me more?
