Blackie is sneezing. He's sneezed about 5 times in the last hour, which maybe isn't much but he never sneezes. It's a dry kind of sneeze like a dust sneeze, not a wet sneeze like an allergy sneeze. He did go out in the rain quite late last night. I try to keep him in at night because, well, he's black so he's invisible after dark, but sometimes he runs out if we open the door. But he was back in 10 minutes, just needed a cigarette or something I guess. (No, he doesn't smoke, but you know how smokers are.) So I am planning to keep him in for the next few days to keep an eye on him. Is there anything else I should be looking for, besides discharge?
