If your kitty is sneezing, sniffling, coughing, has runny eyes or nose, seems congested and has mouth and nose ulcers, chances are it has an upper respiratory virus. The two main forms of the virus are the feline herpesvirus and calicivirus. Once at the vet’s office, the cat may receive nose drops, eye ointments and antibacterial medication, especially if it has a secondary infection.
