New Years day, afternoon I checked my snakes and found a pastel that I hatched in 2012 coiled and dead. I was/ am confused about the whole ordeal because nothing in husbandry had changed and she ate a small rat on the 17th of December and skipped the last two meals. No noticeable issues or complications, just dead. So today I got a necropsy done and the vet said everything looked great except for the liver. Vet said it was very pale (normally supposed to be mahogany color) and it was also swollen. She also stated that the snake was obese and there was fat in the liver. This particular snake is 2+ years about 4+ feet and weighs 1450gs, so I wouldn't think obese?

I'm very glad that it's nothing contagious and wasn't something I did directly, but it sucks. I was wondering if anyone has input on the situation? Should I slow down my feelings? Any other thoughts would be greatly appreciated. Thank you.
