Measured my window frame first like the listing says to, and the adjustable length fit perfectly without any wobble. My cat figured out the flap in about a day, and I like that I can leave the window cracked for air without worrying about her getting out.

Wasn't sure an indoor window door would feel solid, but the build really is sturdier than I expected. The adjustable length made it fit my odd-sized frame without any cutting, and my cat figured out the flap in about a day.

Measuring the window frame first saved me a headache — the adjustable length slid right into my 30-inch opening without any cutting. My cat figured out the flap in about a day, and I like that the build feels solid enough that she can't just shove it loose.
