Hey, slugs are tempting! I've got eight-inch banana slugs and leopard slugs all over the place and the idea of making one into my familiar hasn't escaped the crossing of my mind.
lol I collected them because I have heard of people doing it before, and figured it would be a cool project...They are by a window in the basement now, so I think they would be cl;oser to outside temps. So, I guess they would be fine if I dug through the snow and a few inches into the topsoil and dropped them in?
