Cat owners can expect an upper respiratory infection to look quite familiar. In fact, it affects a cat much like the common cold does human beings.
You'll notice telltale signs such as coughing, sneezing, congestion, fever, runny nose, and discharge from a cat's eyes.
Another thing to check is ulcers within the mouth or around their eyes and nose. Cats will respond to them by pawing at their mouth and nose. These signs are clear indicators of a cat suffering from a URI.
In most cases, a URI will usually resolve itself within one to two weeks. Cat owners can breathe a sigh of relief as this infection is rarely fatal. However, if the condition is bacterial, your vet may prescribe antibiotics.
