My gut reaction, when Toby suddenly died, was to ask "Do you think someone poisoned him?"
I don't know why I asked that. but nothing made sense during those first few hours, so my mind was spinning.
Then Jet was able to talk with our vet, who told him that they were fairly certain it was something called "Twisted Stomach".
I don't even want to write anything about it because it makes me cry. though I am glad to know that it wasn't foul play.
