I used to bring home worms till one day I brought home a snake and my nanny flipped out, "It's a SNAKE!" and I dropped it and ran away screaming. I never picked them up again after that...
My kids bring home worms, we put them straight in our compost, I say thats where we keep our pet worms.
They found a slug and brought it home, then I caught them at the kitchen table putting salt on it (yes I know what it does to slugs). They were seasoning it and saving it for their dad has a snack
for when he came home.....I threw it outside they were most upset with me as they had made it especially for their daddy.
