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.

Very poor design

1st there are no instructions in the package as to how you have to install so I reverted to the instructions here on chewy. 2nd the install instructions state different ways to install, 1 using enclosed suction cups with product. It also says you need at least a 2 inch window sill for installation. Here's my issue, 1, there are no suction cups. I only received 1 piece of velcro and 3 nails. Bad product when manufacturer doesn't take 6 inch marble window sills into consideration. I purchased commercial velcro & put weights on the outside area where the velcro is, giving it time to stick b4 my cat tries to lay in it. I waited 48 hours after install b4 letting my 6 lb 14 year old cat lay on it. It crashed at the first time she laid on it. Not funny! I have other window hammocks made by this company & my cat loves them. I was trying to give her a window where the sun comes in late afternoon so she can sunbathe. Won't happen! I ended up packing it up & donating it to our area shelter. 😪😪

Mr. Kitty loves it!

My cat loves his new window perch. He's a 12 lb. cat and the perch is staying attached to the window sill with just the velcro strips provided. The heating element provides just enough warmth so he stays comfortable and does not get overheated.

Adhesive Failed

This perch was fine for a couple days. I followed the directions and let the adhesive stick for over 24 hours before allowing my cat to use it. After a couple days, the perch fell when he climbed up on it again. Both parts of the velcro strips that came with the perch are still on the Window, but the perch is on the floor. The legs were appropriately aligned as well so that the perch was perpendicular to my wall. That's why I think the adhesive is the problem. Will probably either screw it in place or get stronger adhesive for the velcro strips. I haven't tried the heating pad, yet. Other than that, it seemed to be fine.

decent, but glad I got it on sale

Let's start with the goods: my cat loves it! And it's built pretty solid, which is definitely nice. Neutral: not sure if I'm doing something wrong, but I've never gotten the electric heater to work. For me that's fine, that was just a bonus compared against similarly priced options. Bad: the adhesive on the underside of the velcro that's supposed to hold it up isn't great. The whole thing has fallen down of its own accord (read: without a cat on it) a couple times, pretty clearly because the velcro isn't staying attached to the shelf. I'm just gonna get some of that hyper-strong stuff next time I'm at a hardware store, because the perch itself makes Lieveke so happy I wouldn't dream of taking it away from her! Tl;dr: decent, but imo not worth the money at full cost. If you can't find a sale, maybe worth getting a cheaper product without electricity - the sun does plenty of work for that!

Very popular with my cats

I already have two of these. One is at least ten years old and still going strong. My cats seem to have a schedule of who gets to lay on it. It seemed maybe an additional one would be a good idea. It is incredibly easy to install. It was immediately put into service by my senior cat.

Cat approved

Holds at least 2.5 cats. Quick to install. Has a heating option. Substantially expanded windowsill space (might save some orchids). Was an immediate hit when installed.

Instant Hit

Our cat took to this perch quickly and loves it! Easy install and a great option for apartment dwellers since you done have to drill holes.

Storm Approves

This is so nice. It fit in my window perfectly, and it was very easy to install. After reading some of the negative reviews, I decided to screw it into the window-sill rather than risk the velcro failing. Storm and Loki both love it, particularly the low-heat heating pad. Jagger likes it, but I think he might like it better this winter.

My cat loves it

Perfect size and fits on my window sill well. My cat loves it and spends most of her time on it now.
