FAQ

Where do I measure to select the correct adjustment range on the window mounted cat flap door?

What is the min height to raise window?

This is how high you have to be able to open the window up in order to be able to get the sash into the track.

Does this ideal sash door have good insulating value?

They are ok and really best for more moderate climates.

Can I take it out if I need?

Yep! They are meant to be able to take in and out easily without the use of any tools.

How wide does my track have to be?

We recommend that you have a track that is at least 1" in order for the Ideal cat window door to fit properly.

If the sash is a little too wide what can I do?

Ideal made the sash so that you can trim about 1" off either side just in case there was a small measuring error.

If the sash isn't wide enough what can I do?

There are channels in both sides of the spring loaded adjustment ranges. You can trim a piece of wood and slide it into the channel to act as an extension.

I highly recommend. Really well made

I just replaced my 12+ year old cat sash. It was still in very good condition. However, my cat had scratched the door so much over the years he couldn’t see through and he wouldn’t use it. I would have replaced just the small door unit but part was not available. I highly recommend this product. Well built. Exactly as advertised. Easy to install.

Cat Sash Door for Windows

Great idea! Unfortunately my cat uses his head to push the door open when it's set to only come in. Then the cats cannot come in because the lock is now stopping the door from swinging open because the door is on the wrong side of the lock. We did jury rig it so we have an extra stopper which stops our cat from being able to push it open. Would be nice if the locks had a little more meat to them. If it wasn't for our stopper, he'd push the door past the locks every night. Which again, stops the cats from being able to come back in. With that being said, we love the Cat Sash door for windows!

Great cat door

Overall works really well. Only issues we’ve had are: - when it’s really windy outside, door will flap open and cold air will come rushing in - once on vacation the cats managed to push the lever from in only to out only and got trapped outside.

Quality and Freedom

The quality of this product is superior to any other I have experienced. I do wish the magnet had a little less strength as my cat tries to hold it open with his foot to push his nose through. It gives me great peace of mind to know he has the freedom to go in and out as he pleases when it is cold or raining or hot. It has helped us immensely!

Best Idea Ever!

Love the Cat Sash and our cats love it, too. They learned how to use it quickly and have been going in and out on their own even since. No more waiting at the door for them to make up their mind to go out or come in.
