Review on 🐱 Ideal Pet Products Sash Window Pet Door, Adjustable Width 33-38", Cat Flap, 6.25" x 6.25" Flap Size, White, (33SWDCF) by Nathaniel Collins

As expected, it took my cats a while to get used to it. The youngest is 9 years old and picked him up in about three weeks. The eldest is 16 years old and it took about two months and a long weekend when no one was around to open the door for her to understand this. It's an incredible relief when they don't meow every 15 minutes to be let in or out. currently. Senior is still confused and forgets from time to time, but mostly fine. This is a very well made item, looks like it belongs entirely in the display case. I bought the window locks that other reviewers mentioned so my window couldn't be easily opened by someone from the outside. The panels are clear and the aluminum is clean and matches the aluminum windows I have. If you have a little patience to make life easier for your cats, I promise it will be worth it. I would suggest starting by holding the door open for them and putting wet food on the other side to create good associations for them to use the door. Also the platform on the other side was a must for our setup, we used concrete blocks and built some stairs. Oh, and one more thing, I had to buy an extra seal as well. And my half-open window didn't seal well between the sliding and fixed glass, so I bought some clear adhesive originally intended to seal the underside of the outer door and glued it to the underside of the outer glass.
