I don't know I only had very safe toys in there for them, but I guess anything is possible. He could have eaten something while they were running around the house with me then got a blockage We didn't do an autopsy. I know I should've, but I was out of my mind with shock and grief. I took his body to the shelter and ran in there crying so hard. They sort of just took his body for me and took care of it since I was so upset.
