I just got my first ball two days ago. He is an adult male reduced pattern and is six and a half yrs. old. He hisses quit often but not in a mean way and I just noticed he is drooling. I was handling him last night and he was very friendly and tonight when I went to pick him up he snapped a little at me so I left him alone. I went to feed him and he seems totally uninterested. tank temp. 83 F, 32% humid. Temp. gun says he's 89 F. Please help.
