My rabbit is in 100% tip top shape/health. But over the past week i've noticed that he's got cold wet fur just below his nasal openings. Does's he have a cold? Is this something that should be examined by a vet? Does any one know whats going on. There is no sneezing,no wheezing or shortness in breaths. Everything about him is totally normal, except for his nose. If i could just get some clue as to whats going on and if it's normal or not.
