I recently got a new kitten, a few weeks ago. she is about 3 months old now. I got her from a friend who had found her stray. When we took her to the vet they said she would be fine and we got her shots and whatnot. But recently I have found that she has earmites, so we bought her earmite medicine. but not she has little black things on the tips and edges of her ears. they look the same as the runny things coming out of her nose. I am concerned. Do you think it is just allergies that i could buy a medicine for at the pet store or should i take her to the vet immediately?
