Think it was a stroke. He was just limp. His breathing got gaspy, he had a small seizure, and then he was gone. He was curled up on my chest getting petted by MomRat and myself.
It was quick. Maybe an hour from when we noticed something was wrong to when he stopped breathing. We let his cage mates see him for a little bit then put them back in the cage.
Man...Quilt was supposed to teach the girls we're getting Monday about being cuddley goofballs.
