I noticed tonight that there's a black spot, the size of half a millet or so on my Syrians scent gland. I can't take a picture of it since he struggles about when I try to look at it and brushed aside his fur to look at his scent gland. I found somewhere else that someone had a picture and it looked similar: https://m.imgur.com/xzaoiDU Is this something I should worry about or should I look into cleaning his scent gland? He seems to be playing, eating and drinking alright. He has a sand bath that he doesn't care for or use at all. Any advice is much appreciate. Thanks in advance!
