My JCP Alistaire was coiled up dead when I came home from work this morning. He was alive when I left, making his morning journey to his basking spot. This comes as a total surprise to me. He ate last week, but refused food this week, which was not surprising, since he is an inconsistent eater. I just cleaned healthy looking poop and urates out a couple days ago. His behavior has been normal, basking, moving around, and inquisitive. He has been eating fairly regularly ever since we got him past his winter fast. The min and max temps recorded on the thermometer don't show anything unusual. Nothing higher or lower than it should be. Nighttime low of 80 on the basking spot, daytime high of 92ºF. Cooler end of the tank gets down to high seventies. Humidity has been maintained between 44-74% according to the min/max recorded. I observed no respiratory symptoms, or anything at all out of the ordinary, in fact he had been eating so well, I was hoping he was finally going to grow a little more. He has been shedding well, and regularly, and his skin looked amazingly healthy and iridescent. No mites. Clear eyes. Clear vent. No neurological signs (IBD is a scary thought that has crossed my mind). I'm calling the vet tomorrow morning to inquire about necropsies, and what they may cost.... Anyone ever had one? any ballpark idea what they might cost? I need to know what killed a seemingly healthy animal so rapidly, and if there is any possibility it has spread.... I have had him since 2009, if I remember correctly.
