K&H Thermo-Kitty Hut, Sage

This cat warmer is shown with a an 8 lb. cat...or less. It works but was too small for my cat. He is 16 yrs old and very thin, but weighs about 13 lbs. They should put a size guide on it. I had to cut off the bonnet so he could sit on top of it.

The bed itself is nice & soft, but I was disappointed with the heater, which is not the full size of the bed, but instead a tiny 9 inch by 9 inch square, which does not provide much warmth. You can purchase the exact same type of heating pad (made by K&H Manufacturing K and H Pet Bed Warmer) or larger for much less & insert into any bed with a zip off cover.

My cat spends about 85% of her time in this bed during the winter. It doesn't get overly hot on its own, but it warms up significantly when she is sleeping in it. I also haven't noticed a significant jump in the electric bill when its own. This is the second year she's had the bed and the heating element is still working fine (though I'm not sure it will survive another year, but they are fairly cheap to repace) She is a small cat though--she weighs about 10 pounds--and she fills up the bed nicely.
