The K&H Self-Warming Pet Crate Pad was a very disappointing product, though nicely made. I had ordered it in hopes of adding a bit more warmth for a friendly but timid outdoor feral cat that seems to have adopted us; we've set up shelter for her in the backyard. The "warming" effect of the K&H pad was so slight as to be unnoticeable. I had also ordered a different self-warming mat (the Slumber Pet Thermal Cat Mat), one I've used before with my indoor cats, but was concerned the slight crinkly noise the Slumber Pet mat makes would scare the timid feral right out of her new insulated outdoor cat house. I did a pseudo-scientific side-by-side comparison at my kitchen table, using just the warmth of my hands, one hand placed on each mat for 1 minute. The winner was undeniable. The K&H crate mat was just a mat; I didn't feel any heat building while my hand was in place, and any warmth from my hand was gone from the mat almost as soon as I lifted my hand. The Slumber Pet mat was impressive; my hand started feeling warmer while resting on the mat. After the 1 minute was up, I could feel a definite warm spot where my hand had been, and the warmth remained for a short while after removing my hand as well. Cat-testing revealed I could have skipped my own test. Three of three indoor cats preferred the Slumber Pet warming mat. The feral kitty happily nestled on her Slumber Pet Warming Mat as soon as I put it in her house, and she didn't care about the faint crackly noise it made. When she comes running out of her house to greet us, she is toasty warm. That's the most important part. I will be returning the K&H mat. Sorry, K&H.
