Judy, that's so cute! What little smarties they are!! I know what you mean about the cold/hot situation. It's crazy isn't it? Kandi's mom gets cold, too. I put an insulated sweat shirt (for humans) with the sleeves cut off and the sleeve holes sewn up in her kennel. If it gets too cold she can crawl inside of it like her own little snuggle sack. If it is too warm she can lay on top of it. It works pretty well.
By the way, I think we all need to see more pictures of Gizmo and Kandi...
