I got a new kitten from a rescue about 3 weeks ago. I was told he was healthy; however, we came to find out he had conjunctivitis and a bad ear infection. He got my 1.5 year old cat sick as well. My 1.5 year old cat has feline hyperesthesia and asthma. Around his mouth is white (he is a tabby) and on the left side (right in the picture) above his mouth, it is discolored. Could this be something serious?
