Can a cat with a respiratory problem p it onto a bird?

I don't think they can, but to be honest I am not sure. I starred your question, one of my contacts is a bird expert and maybe she will see this. I am glad you have a vet appointment coming up, I would just keep everyone calm til then, sounds like a very minor cold and I am sure everyone is going to be just fine. Just, as I am sure you know, keep an eye on everyone and if anything gets worse, phone your vet. Best of luck!!!
