We are loving this petdoor. My cats are slowly getting used to going in and out through this door rather than our sliding glass door. Now they have free range to enter the patio as they wish. We have removed the magnets to help them get used to it. My wallet is happy because now we do not need to to leave rthe sliding glass door open which causes the AC and/or Heater to run constatly driving up my cost. This is a very high quality product and better than many of the cheap competitors. Highly recommended!!!!

Great cat door
This cat door window was easy to put in. One of my cats still has a little trouble using it. Due to the fact she is somewhat skittish of anything different. Now the other one blew right through it. Less than an hour. He wanted to get in his new Catio!

I bought my doggie (window) type door back in January of 2022. It has been the best thing I ever did for my pomerianian. She learned how to use it and when I have to leave for a few hours I have peace of mind she is able to let herself out. Also, when I dogsit her son, he also has learned (from her his mom) how to go in and out the doggie door, so he is not peeing on my furniture in side the house, so no more doggie diapers either. It has been durable to this day. I installed it in a window and it juts right up to my back patio so all I had to do was add some bricks to make it easy for the dog's height. Don't wait! Get it!

Great pet door but the instructions were for a sliding glass door model not the sash window model. We figured it out but the correct instructions would have made it a lot easier!
So far so good!

Thermo Sash 3e Pet Door for Sash Windows
I bought this door for the catio I built outside a bedroom window and it is exactly what I was hoping for. Keeps the cold out and the cat happy. Being able to change which side the flap is on is a huge bonus. It's a well designed window/pet door and built to last. I'm very glad I bought it!
