I can tell you.
Well, I never hate any, but both my cat and my ferret did.
They can't hold from running around the house after some bbs that felt to the ground. Eventually they catch it... and eat it.
I can tell you one thing that my father told me when I started pooping on the toilet:
What ever goes in, it will go out soon enought.
End of the story. There is not hyper-unstable chemicals involved in the process, no belly-detonation or anything.
