I asked for a video of this snake and she sent me one a few minutes ago. He is very lethargic and instead of tongue flicking he would just stick his tongue out and lay it on her arm for 30-40 seconds. It happened 3 times in a 5 min video.
I have saw enough, I thanked her for her time and suggested feed him one small mouse a week and see a vet if he doesn’t get better. I don’t know whether I’m more mad or more sad about this whole situation but it sucks. I will probably take the numerous suggestions here and start with a baby boa from a reputable breeder.
