My roommate has been sick the past week and he just found out it is pneumonia. I know it can be contagious between humans, but can cats catch it from us? I searched google and found one yahoo! answer about it, but the person spelled pneumonia "namonia" so I didn't even bother taking the answer seriously. One of my cats is a three month old kitten, and I'm worried since his immune system isn't fully chargedyet.
