I had checked on her earlier this morning and she was perfectly fine then I went to work and came home and checked on my snakes again and she was dead. She was just over 18 months old had a qt and everything when I first got her. When i checked her over for any signs of a cause of death I found a little blood on her mouth but there are no visible cuts or anything at all. My question is how could this have happened? The only thing I can think of is internal bleeding but what could have caused that if in fact that is the cause of death? Right now she is in the freezer and I am trying to find a vet that is less than 6 hours away from me who actually knows more about snakes than me. If I am able to do that I will have an autopsy done on her but other than that any thoughts on what could have caused it would be great. Just to give more back ground she last ate on Wednesday and ate perfectly fine, has fresh water every morning, bedding got changed 2 days ago and I use aspen. When I found her she was sitting in a ball as normal for her with her head under her body I just noticed she didn't look right so I took her out. She was in a 40gallon tank slider top temps were 82 cool side and 91 warm side because I just started lowering temps. Humidity was 74%. I have since taken that enclosure out of my snake room and it is outside right now so I can sanitize it. I think I covered everything. Oh there was a slight trace amount of blood in her mouth but not much there was a decent amount on her upper jaw right by the heat pits and it went down her mouth onto her lower jaw, kinda like when you blow a bubble with gum and it pops on your face, that kind of look to it. Thank you everyone for any information you can offer me.
