K&H Pet Products Lectro-Kennel Heated Pat

I bought one of these for the outdoor cats I care for who have grown to love and trust me, but still want nothing to do with the indoors or being picked up. The pad arrived just in time for the cold snap. The cats absolutely loved it, one cat clung to it from the very moment I plugged it in to check that it was working. I had to dump him off to set it up in the shelter, and he was back on the instant it was down again. The box indicates you cannot use this heated pad with an extension cord, which meant it couldn't go in the greenhouse. So I build a platform on the patio using cinder blocks to raise the pad off the ground and keep it fully supported, left the shipping cardboard under the pad but on top of the cinder blocks, then surrounded that with upended cinderblocks to act as wall supports, and wrapped the outside with trash bags I split open flat. On top of the upended cinderblocks I placed a Maccourt Supertub, flipped over to act as a roof. It's as if they were made for each other. Then I layered more bags over the top , hanging off the edges to protect against driving rain and act as a drip edge, and weighted that all down with found bricks. As it began to snow, I noticed the wind was blowing snow into the entrances and the heat of the blanket was melting it. So I used cardboard and planters to block off the entrances and make a sort of S shape exit for the cats but to block the snow blowing in. Eventually the falling snow would mostly block 2 of their 3 exits, which helped retain their body heat, and the hide started to look almost like an igloo. Even at 16 degrees F, minus wind chill, it was warm and cozy in their hide. If you stuck your hand in and touched a spot of the heated matt, you hand was immediately warmed. Instead of huddling together in a mass together looking miserable, the cats were visibly happy and actually went out to play a number of times. I was worried the cats would wind up melting so much snow they'd electrocute themselves, even though the packaging specifically mentions the device is intended for a wet dog to be safe, I didn't know if I believed it or not. Thankfully, the promises were true, the pad really worked wonderfully! I liked this so well I bought another. -- TLDR; They're awesome just get it!
