Air it out and await the cold :)

Like you will read some cats take to it right away perhaps with the help of an old t-shirt on top of it but my two girls ( mother and daughter) avoided it. I tried to trick them so i placed their can food in a corner and put the bed in front of that. They stood over the bed but refused to step in it to stand and eat. So I gave up and thought maybe when the bed had aired out some or when it got cold they might use it. Today was that day. The bed is on a shelf by the window where they like to lay and look outside. The Daughter cat ventured into the bed and lay down this morning as it is a somewhat cool and overcast Fall day. She slowly lay down in it but when I had come back from errands over an hour later she was still in it and looking like she was a bit enlightened for the experience. She has insight into a "warm place" her mother does not (yet)
 The bed was just the right warm for a cat. So now that Daughter cat knows Mother cat will figure it out and use the bed sometime in the future when it is much colder and then there will be a spat over ownership at some point in the future. Mother cat is a long, short hair cat. Daughter is a shorter cat with a denser coat so she handles the cold better than her Mother.
 It took some time but it happened.

I'm going to order a second and let it air out then put that in Mother Cats "hideaway spot."

Works fine as long as its above freezing.
Once it gets some ice/snow on it, it curves and you need to go out and manually straighten it

This block is easy to install and with this very cold Winter you will see that the cold is kept out.  Get it.  It Works!

I haven't tried it yet because it's cold and wet here, but I have opened it and it looks top quality. Can't wait for next spring/summer!

Use it at work (air conditioned office). Really happy to not be freezing to death every day.

This is so adorable but it is a shame I had to take it in until the ice and snow goes away since it would have gotten covered with snow when my husband shoveled.  Can't wait to get it back out front, if this weather ever clears here in Pennsylvania

As usual, it was what I wanted.  Just a thought though.  It was SO COLD outside while it sat on my front porch and when I brought it in to install it, it wouldn't install right.  So, I waited until later that day when the package warmed up and it installed fine.

Very interesting technique. I think it will give me something new to try this winter while I'm hibernating and avoiding the snow. Thanks for the inspiration!

Needed it to keep cold (AC located in bad spot) air from going downstairs and it worked and fit nicely.  Very pretty piece.

Our a/c went out and I ordered this hoping it would help me stay cool at night while waiting for a repair. It works best if you leave it exposed to the air (no pillowcase/don't tuck it under bedsheets) and BEST if you put it in front of a fan or some sort of airflow. Absolutely love it!

So far so good.  Will have to wait for cold weather to see if the flap freezes up as other have noted. Only draw back is the sound of rain hitting the gutter and piping into the bathroom through the ducting. lol

I found this thing at the dump. As I am a gas fitter I spent about an hr tinkering. Blew it out with compressed air. Works like a charm!!!
Whomever had it previously left it outside for a good while too. Can't wait to heat my ice hut this weekend!!!

I love you when it is cold outside! This is great but it can heat up a room so be careful ! Keep the vents clear and dust free

I have this and will use this when I get stuffy.  I wanted to have some ready because it is hard to find in the winter time.

It would have been nice had it got here when it was cold! I waited for several weeks for it and by then it wasn't cold and I was moving back to Florida from Kansas. I will have it if I go up north in the winter I guess.

Impulse prime day purchase. Its fun to walk around and check the temps on various things. I was using it to find how cold our AC was blowing in certain rooms.

The price, part matched, works as it should and I now enjoy cold air!
