does the deluxe kitty sill with bolster come with the heated pad?
Answer by ChewyMar 18, 2018
This Kitty Sill does come with a 6-watt heater to keep your pet warm all year around.

can this be used on aluminum sliding windows?
Answer by ChewyNov 02, 2018
This product needs to be placed on a window sill that has a depth of at least 2 inches deep.

Can I use an extension cord for my indoor heated window seat
Answer by ChewyNov 21, 2017
MET requires that all manufacturers put the extension cord statement “Do not use with extension cord” on every item that is MET listed by UL 499 standards. This is because they cannot test every extension cord on the market in conjunction with K&H products for safety. Also, MET suggests that an extension cord is not recommended as a permanent fixture and should only be a temporary solution when using any electrical product.

How do the "fuzzy fasteners" work without tools to provide safety and security? Secondly, are the support brackets made of plastic or wood?
Answer by ChewyFeb 21, 2019
The Velcro attachment may be used on any window sill. The strips use adhesive to stick to the window. For the complete instructions, click the “Instructions” tab, next to the “Description” tab, just under the product photos where a link is available.  The support brackets are made of durable plastic.

Great! Cat loves it.

I have a 16 pound cat who loves this heated perch. He's big, but it's big enough for him. I screwed it to my windowsill just to be safe because I've had a perch fall in the past (not this one). I was a little worried because it is plastic, with plastic legs, but it seems solid. I'll update it it breaks.

Great Idea, Poorly Executed

The perch itself is a great choice and well constructed for those who are hesitant on its support being stable enough. But unfortunately the thermal perch is a total let down, the heat pad doesn’t even warm up a pillow, which is how you test it. Unfortunately the heating wasn’t not worth the price.

Great for senior, arthritic cat

My 15yr old senior girl loved her electric blanket, but it would automatically shut off. This product only heats up when she is on it. The only problem is my girl is tiny and sometimes I have to put some added weight on the pad to get it really warm for her. I'd buy it again!

Cat loves it

This is one of the cat's favorite spots in the house. It is in a window and he loves it so much, most of the time he isn't even facing to look out the window. He just curls up on it and takes naps. It gets noticeably warm to the touch but uses next to nothing for electricity. The only drawback is getting replacement covers. In a bit of time, the cover was beyond washing, and I had to purchase a whole new one to get a new cover. That's a little lame. However, he likes it enough, that he got a new one. BTW, he has a second one in a different window that is not heated.

Happy Pets

We bought two of these seats years ago and put them in different areas of the house. They are used daily by our two cats. We always find them curled up on them. Our nine month old lab puppy has also started joining his brothers on them. These are seriously sturdy. They’ve been in place for over three years now.

VERY DISAPPOINTED! Adhesive did not hold!

Thoroughly disappointed in this product. If I hadn't tossed the packaging, I'd return it for a full refund. I have marble window sills so using the screws was not possible. I used the adhesive velcro strips. BIG mistake. They do NOT hold. After applying them in the correct spots on both the sill and the underside of the shelf, I stuck the shelf in position and waited for 24 hrs. for the adhesive to cure. It felt alright at first, but then my cats started using it - Zelda only weighs 8 lbs. and Teddy weighs 13 lbs. It started to let loose immediately. I had to remove the shelf completely and Zelda is heartbroken because she is 15 and the heating pad allowed her to look out the window for hours.

She likes it now!

My cat is a little chonky and couldn't sit in her favorite window without it being open. Which is fine in the summer but the dead of winter is an issue. It took 3 days for her to decide to like it and is now her favorite spot.
