He became off balance and twitchy when he walked (what little of that happened). The only difference that night otherwise was that he ate 3 adult mice beforehand. All of my albigs picked times of the year after being adults that they went underground and were not hungry for 2 weeks, 1 week, or more, so nothing was unusual there.
Its strange he was normal until that day, but only a bit lazy that day, then that night he went from somewhat normal to twitchy, shakey, and eyes sunken in 1 hours time. He ate for the first time in 2 weeks an hour before he died. This bothered me because the 4th mouse went to Sobek, she is still the same as always, absolutely normal.
The lack of symptoms and sudden onset so quickly really caught me off guard fast. Been wracking my brain to remember anything out of the ordinary in the last 2 weeks with him. The last thing he ate before this was a few big hissers, 2 weeks or more ago.
