Find outdoor cat heating pad at Target.

You don't have to use a "heating pad" (& therefore keep your costs down). Instead use either a Mysterious Purr Pad, and/or a Snugglesafe. Both will do the job of keeping the cat(s) warm without the expense, or danger of having a heating pad being used outdoors. Remember, there are some dangers involved with using an "indoor only" product (i.e. a heating pad) outside. Also it eliminates the dangers of running an extension cord(s) outside, or for a long distance. No tripping over the cords, nor any animals chewing the cords & getting injured.

Compare Heated Cat Pad to Lectro-Soft Outdoor Heated Bed

What a great idea! For the last several years we've used a regular heating pad for our darling outdoor kitty-cat. We've tried to be careful to give her good padding on top of it as well as watch out for overheating. It would be great to have a heated bed designed for a cat's safety and for household safety.

Cats have the tendency to chew upon electrical cords and this can prove fatal. If you are using an electric heating pad, ensure that the connecting wires are located outside the cat enclosure and are insulated. Even wires embedded within the floor of the enclosure or the surrounding soil aren’t safe from being dug-up by a cat. Even if the wiring is internally located, use an outdoor extension cord to ensure that the wires are stretched beyond the cat’s range. In this regard, choosing a safe, under-floor heating system needs particular attention. Many of the manufacturers tend the leave the wires hanging just beneath the artificial surface. This is a safety hazard since the vinyl surfacing is vulnerable to being torn apart by an aggressive cat.I was reading your post because I wondered if I could use the straw, which I do use now with the new K&H extreme weather heating pads I just bought. I was concerned about fires but it seems you use both straw and the pads. I have ‘doors’ also on my shelters to help keep the drafts and cold out and they are find with them. I am getting cat doors to install to give even better protection. Where did you get that large black plug connecter? I need to plug in 3 things in a 2 thing outdoor outlet. I also bought a heated water bowl since water is already freezing here. Thanks for any info.
