Review on Large Interior Cat Door with Removable Grooming Brush for Adult Cats up to 35 lbs - Easy Install, Detailed Instructions & Screws Caps Included by Kristina Soucy

I didn't measure the thickness of the door, I assumed they were all quite similar. I haven't measured yet but the screws are about 1/4" too long for my door and the comb part curves a little. Although to be honest the curve is actually pretty neat. I was very careful with the template provided which is light weight cardboard or regular cardboard depending on how you look at it and it was a bit out of shape, maybe about a half inch to the bottom. Not bad, one more quick puzzle zoo and it's done. The screw holes are EXTREMELY close to the cutout, wow if we speak of a jittery experience. This can be a 1/8" gap. Be very careful here. The screws went in fine and it works. It's a bit bent at the top because there aren't any There is a top screw but like I said it's a clean looking hole in my door Overall good just not easy to hold the jigsaw that close to the screw holes.
