Saying prayers for Limpy. I sure hope he shows up soon. Please keep us posted.

Have you heard of a product called Snuggle Safe Heat Pads? They work well for us keeping outdoor kitties (we live in Alaska) warm. You put it in the microwave for a few minutes and it stays warm for 12 hours. It really works. Depending on how large your shelter is, 1 or 2 of them should heat it up for anyone who decides to stay overnight.
