Over the weekend Tortilla started sneezing and not just a little. She has been sneezing about 3 little clusters of sneezing an hour. The dogs tend to sneeze once in a while but Tortilla never has. Should I be worried she is falling ill? She has been eating, drinking and pottying normal. I don't see any eye or nose drainage like the kitties I see at shelters that have little cold. She is behaving normal just sneezing quite a bit.
