Grossest feed was from my first bp. He was really sick when we got him (but we didn't recognize it since he was our first snake). We had him for a few weeks, he wasn't eating, he was very very skinny, etc... We were trying all the old tricks of assist feeding and such. I didn't watch for this one, but my dad brained one of the little mice to try to get the snake interested. I never saw it but it's sooo gross to think about.
