Just noticed a black brittle tail end, which I have seen before that has gone away this time the very end broke off and she didn’t have pain when I was touching it. Makes me think it’s the very early beginning of tail rot. I realized my UVB light might be old and I had a friend take care of her for a couple weeks maybe giving her too much apple. Thinking of going to the vet, but have also heard of soaking the tail in betadine. If it’s tail rot I feel I caught it early but I don’t want to skimp on the vet visit if it would help.
