Hello! I recently took in a stray/semi feral cat named Terry. Recently he has had some black/brown crusty stuff in both of his nostrils. I have never seen this before and I am a bit concerned. Since he is still a bit wild, he does not allow me to touch him at all so I am unable to get a close look or try to wash his face. I had him neutered and all bloodwork done. The vet said he is healthy with no diseases, but his nose was fine at that time. I plan on taking him back to the vet soon, but I wanted to ask for any advice. Thank you!
