K&H Pet Bed Warmer, 4 Watts, Small 8-1/2 By 9-1/2 Inches

I purchased the K & H warmer from PetSmart with the cover, but I've moved the warmer unit between different cat beds. The cover that you can get it for it is a flat mat and good for cool spaces, but for really chilly places like right in front of a drafty window -- putting it under the cover of an oval or "cup" style bed will keep your kitty toasty and happy.

Not only do the warmers fit nicely under the removable cover of a cup or oval style bed, they also slide nicely into most kitty "hammocks" (the sort you can cantilever on window sills). Great for winter bird-feeder gazing!

Safety note: if your kitty "milk treads" a lot and you put the warmer directly under the cover of a cup style bed, make sure to keep your kitty's claws trimmed.

We have an indoor cat who is getting up in years, and is always looking for something warm to lie on. Since I have trouble typing with a cat on the laptop, I bought one of these heaters a few years ago.

They have about the right amount of heat for an indoor cat who is just cold-basically it is about the equivalent of sitting on a chair that a nice warm human just got up from. FYI 13 watts is about the equivalent heat from two old-fashioned Christmas lights.

One caution- this is only the heating element. It is made out of vinyl, sort of like an icepack, and is probably not something your animal will want to sleep on directly. It definitely needs a cover of some type. If you animal is a chewer or scratcher, you will probably want a zippered pouch for it.

The size makes it a very tight fit into the bottom tube of one of those scratching post/houses made out of carpeted cardboard tubes. It is flexible enough to roll up and surround the cat on...Read more

I ordered this for my little yorky because my bedroom can get cool in winter and I wanted to make sure she was warm. Her little bed was quilted so I just put it on top and added a little blanket to cover it and now she sleeps nice and cozy on it. She used to sneak in my bed in the middle of the night but now she stays in her cozy bed.
