I have my cat Pawpaw for about 6 years...He lived in my apts with another owner who moved, took him with them, and he walked back to the apts. Two years ago i took him to the vet cause he was sneezing alot and coughing, runny nose with a lil bit of blood in it. The first Dr I took him too didnt really do much but said he had a URI and gave me Clavamox, so he took it and it went away. But since then it has come back a few times and goes away. I keep him inside so he isnt coming into any contact with other cats or outside germs. The last vet I took him too was pretty much the same way...didnt show much concern and gave me some Clavamox. Can cats die from URI? He still plays and eats alot...he still talks alot and yells atme when hes mad....hes actin the same pretty much ....I just want him to get better and be happy...not stuffed up and drippy nosed
