A few weeks ago my 5 month old sulcata started loosing weight. About 2 grams a day. I've been watching him in his soaks and he hasn't been drinking. He stopped eating as well. His energy level stayed the same nothing to alarming. He loved his head rubbed and when I rub his head he always opened his mouth so I've been able to put soaked mazuri mash off my finger tip into his mouth to get him to eat. Last night before bed I put him in his hide. This morning when I checked on him he was still in his hide which he usually is already up basking. This time he never came out. I found him dead. His heaviest weight before weight loss was 65 grams. Yesterday he was 50 grams. His weight this morning dead was 43 grams. I did a autopsy to see if I could find anything wrong inside. I found this giant uric stone in his bladder. I've kept him very well hydrated and raised the "wet" way 80ish% humidity, 100 under Che in the hide,110 under mvb, 82 room temperature same as night temperature. His diet is mazuri and it being winter time store bought greens of romaine and collard greens and prickley pear cactus. I'm trying to figure out what caused the uric build up in the bladder. It's a huge stone about the size of one scute. Maybe I'm in denial of him being dehydrated because I feel I kept him well hydrated and soaked frequently. When he was healthy it was twice a day morning and evening for twenty minutes. When he started losing weight and I noticed he wasn't drinking it was four times a day. Here's a picture of the stone and some very odd bruising type marks on the carpace that just showed up when he died. His plastron did start to feel a little softer than normal. His carpace was hard but sounded a little hollow when tapped on.
