So I may have made my Mama Heating pad wrong, so I wanted to see what you guys think... I took hardware cloth and made a cave with it, attaching the sides to a board with another board in the front to help the cloth keep its shape and not collapse down. The Front of the cave is about 6 inches high in the center and slopes down toward each side. The back also slopes down. The heating pad is laid on top of the hardware cloth. I laid a towel over that to help hold the heat in. So far everything seems to be working fine, the little girls hang out under there and come out and eat and "play" and then they go back in to warm up etc. But in looking and reading more, it looks like maybe I should have mounted the Heating Pad along the underside of the hardware cloth so it actually touches the babies. I think I need to remove the towel on top, I just read where they may try to eat the towel and I don't want that to happen! Below is a picture, its not a very good picture, sorry. I will take a better pic of it today after work...
