My cat, Jacques, is sneezing a lot and one of his eye's looks kind of squinty. He has an upper respiratory infection when we first adopted him. We took him to then vet and he has been fine since then (about seven months). I'm not sure if this is the same thing or just a cold or allergies. And if it IS a cold or allergies, do I need to take him in to the vet?.\ He seems to still be eating and playing a little bit, but sleeping more than normal. The other cat, Spencer, doesn't have any symptoms. This just started yesterday. Any advise?
