Pet's info: Cat | British Shorthair | Male | unneutered | 5 months and 5 days old
My 5 month old kitten has been on antibiotics since Monday following the cat flu. He doesnt seem to be getting any better hes started breathing with his mouth open. I was also told on Monday he has a heart murmer. He was hand reared by myself and husband as he wasn't wanted by mum we bottle fed him and his siblings. The other kittens are on antibiotics also but they don't seem as bad as him my 2 adult cats also have the cat flu. I'm worried about him breathing with his mouth open and just sleeps
