Hello, we have a 3 year old cat (Ziggy) in fine health and up to date with all vaccines. On Tuesday we adopted a 10/11 week old kitten (Crumpet) from a local shelter foster family; he had a cloudy eye that the foster family had said had ben looked at by their vet, cared for with antibiotics and needed no further treatment. The next day, he started sneezing and we wanted a second opinion on the eye, so we took him to our vet, who says that his eye is still infected and that he has cat flu. He has remained in quarantine since he arrived at our home, and will remain so whilst we care for him. I've never had a cat with cat flu before, and only ever had single cats, so my question is: if Crumpet proves to be a cat flu carrier, what risk does he pose to Ziggy? We cannot keep Crumpet in quarantine forever, but at the same time I don't want to knowingly put Ziggy at risk of getting ill. I'd appreciate any advice you could share. Thanks in advance.
