My kitten won't stop sneezing. He is maybe 10 weeks old -- a rescue from the side of the road, so that's a guesstimate. His eyes look funny...like his eyelids don't always fully open in the inner corners of his eyes. Sometimes the sneezes are forceful, and sometimes there are two or three tiny ones in a row. This has been going on for a few days now. Sometimes it seems like he can't breathe, but then he gets over it. There are two older cats in the house who are not sneezing. Kitten has taken to eating the older cats' food instead of kitty chow, but we have removed it from his reach for now in case he is reacting to the food. Is all this cause for alarm?
