My cat had kittens about 2 weeks ago. They just opened their eyes and one of the kittens makes this sound. It sounds like it hisses and sneezes after that. I think it's got asthma but can you just tell me if it does or not. My little sister thinks its hissing and spitting. My mum pointed it out first. I'm very worried. If it does have asthma what do i do?
