I have 5 foster kittens in my care right now with an URI. Two of them seem to be feeling worse than the others. They are very stuffy. They have all been on meds since Fri. I read a few older posts about this and I think I will try the steam treatment but I was wondering about nose drops. Is there a way to make them. I am pretty sure it is a saline solution. Can you use a little salt mixed with water?
