My het snow conda is refusing to eat. His last accepted meal was 4 weeks ago. He was eating off tongs perfectly fine until one day he started hissing, puffing up, and mach striking at anything that moves near him. I try drop feeding and he refuses the meal. I gave him extra clutter to hide in his enclosure and it helped a bit with his anxiety, still won't eat though. He was always a sassy snake, but now anytime I open the enclosure he becomes defensive even when I'm just spot cleaning or changing his water. I don't think trying to feed live to stimulate a feeding response or scenting a mouse will help since his issue is my presence more than anything. He hasn't gotten noticeably skinnier yet, but I am concerned that he will continue refusing meals until it's an emergency for him.
