Our friends at Pip's mailed us a special package for Graystripe (the feral we feed)--warming discs for his shelter! I had no idea they were so nice. They are heated in the microwave and stay warm up to 12 hours. They are called Snugglesafe and have nice fleece covers that are removable for warming. I tested one on Tucker, and he gave it two paws up (especially when I put it under the Christmas tree skirt)!
Thanks so much, Pip!
Benny had to inspect the package.
