Please help me my ball python "thor" has been very angry for the past few days. I've had him for about two months and [he or she] has always been very mellow and curious. Thors tank is 80 on the cool side and 90 on the hot with a half log and a tree and a water dish big enough for him to soak in. I feed him a hopper about once a week. A week or two ago i tried a larger mouse he ate it but it stretched his head out alot. I think he may have gotten a wood chip stuck in his mouth that was on the mouse. I feed him in a seperate enclosure. Now when ever i try to pick him up he just hisses at me. He only sits in one corner of the tank and hardly moves. I am so worried please help me. Thanks
