Sadie has been sneezing all evening! It started yesterday and has gotten worse today, she sneezes a couple of times every 5 mins or so at the moment, occasionally more. She's an indoor cat but does this make any difference when it comes to catching colds? We've also not cleaned the flat in a couple of weeks but it's not dusty really and most of the stuff on the floor is her hair haha! She's not off her food or anything like that... but should we be planning madam's first visit to the vet?
