I had a really young ball python, a spider, who died today. I found him in his cage and around his head and a little bit lower was really stiff and curled while the rest of his body was really limp and almost squishy feeling. He seemed a little weird when I got him yesterday when I picked up him and 4 other snakes, all of which are perfectly fine at the moment. When i found him he was coiled up and the corner of his enclosure instead of being in one of his two hides. He had water and had just been fed the day before we got him. They said he was feeding on fuzzies at the time. When I took him out of the enclosure the back of his body was completely limp while his head was still tucked down and super stiff. The left side of his mouth was slightly opened and had some of his substrate in it. The substrate is not something that would be big enough to kill him if he where to swallow it. Also after picking him up some liquid dripped out of his vent(?) and upon further inspection I noticed that area had some red and his pelvic spurs where sticking out fully. After determining he was dead we cleaned his cage out, in the event this is something that could infect the other snakes, and we found a weird blob of regurgitated fur and other nasty stuff. I am going to contact the original owner in the morning and ask if they knew anything about what could have happened, I just really want to know what this is and if any of my other snakes can get it.
