Hi, Late yesturday our big kitty panther started to cough alot, came on real suddenly. He went to the vet this afternoon and it looks like he also has a upper respritory infection and he is on clavamox. Now I feel bad because I wonder if he got it from tuffy. Tuffy has been in the house along time now so I would have thought the others would have gotten sick long before now. The vet told me not to feel bad and panther might have got sick even if tuffy wasn't here. I hope we don't have to go through this with all the cats.
