I am thinking of adopting a cat that was rescued from a cat hoarder. He has proved negative for both FIV and FeLV, but has a lingering tendency for one eye to tear. The foster mother, a well-known cat expert, is fairly sure that this is due to calicivirus rather than herpes. My question: I have read two opposing accounts of calicivirus on the Internet. One says that the cat remains infected with the virus and periodically sheds it, as in herpes. One says that most cats eventually clear themselves of calicivirus. Which is correct? Also, he has red gums, which the foster mother says he didn't have originally, and that this is a standard reaction to losing baby teeth. I already have one cat with chronic gingivitis, so am a bit wary of a cat with red gums, for it seems that calicivirus can be a cause of gingivitis (the cause of my other cat's gingivitis is unknown). For details, see my question in the Health Forum.
