My large female hognose died unexpectedly tonight. She refused feeding the last four attempts (over about a three week period) which is odd for her (hognose are usually trash cans and she's no exception). However I didn't really think much about it since she's a good size and it is breeding season (I did put my male in with her but never saw any locks or any signs of ovulation). She looked in almost perfect condition when I opened the tub, in fact it was only the fact that she didn't hiss that tipped me off that something was wrong. I had to flip her over and really check to ensure she was dead and not just extremely lethargic because she looked 'normal'. I had attempted a feeding three days ago and she had hissed and displayed but showed no interest in eating. The only thing 'wrong' on her when I looked was the appearance of a noticeable widening of her tail just past the vent that wasn't there when I last looked in on her.
I feel just awful that I didn't take her going off feed more seriously, but I'm so used to my snakes going on and off feed as they see fit that I didn't think anything of it.
I'm not sure how old she was, I've had her two years, she was an adult when I got her.
She had the best personality! Every time I opened the tub she was right there to hiss at me and came out and lifted her head up at me, but if I picked her up she calmed down instantly.
