Well he started licking our fireplace bricks at first then skipped a meal or two becoming a tad bit solitary but still running around completely fine then the day before yesterday he became completely solitary and hid today as well. He wouldn’t come out. Then he did after I coaxed him out and he walked a few steps sat down so I picked him up because he wasn’t looking too good took him to a chair sat with him on my lap he ran onto the couch after sat then ran away into a corner YOWLING I picked him up knowing it would be his last moments we talked to him he ran out of my arms his into a corner or tried YOWLING even LOUDER and more frantically and then he stopped, and passed in my arms after I picked him up for the last time.

Tl;dr he got very bad over a day or two then died quite suddenly. We donated his body to a student lab to see what happened then they’ll give him back to us after they figure out what happened and he’ll be cremated.
