My kitties are now about 6 months old. They both had severe Upper Resperatory Infections when they were about 2-3 months, one of them also getting severe herpies in her eye. This sneezing is not nearly what is was like before so I am just thinking this is a minor reaccurance of the URI or allergies. Can cats even get allergies? Any thoughts/suggestions? Should I take them to the vet right away or give them a few more days to see if it gets better?
