I have just noticed hat my kitten has a bit of hair loss under his mouth and I’m not sure what the cause of it is. He goes outside quite a few times and I don’t know if that allergy or not. And how can I help treat it?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Milo! If it is only a small area of hair loss it could be from him hitting or rubbing on something outside or an altercation with another cat. Other causes of hair loss are: skin infections, allergies, chin acne, ring worm or mites. It is hard to advise you on at home treatment with out seeing a picture or examining Milo. If the skin is not raw my best advice it to leave it be and monitor the area. If the area increased in size or the hair doesn't start to regrow then you should have your Vet examine Milo. I hope this helps and I wish Milo the best!
