My "kids", I have 3 have , were recently diagnosed with the Feline Herpes. I've read several Q and A's so far and it's all confusing. I'm on day 3 of treatment with Famciclovir 125mg. twice a day.The sneezing has subsided greatly but they are all sleeping constantly. I'm not used to seeing them this way and it makes me nervous because they can't tell me how they are feeling. Any help, advice?
