My twelve year old Tabby has become fat, so the old door became too tight for him. I replaced the door. I agree, the hardware/screws are horrible, but managed with a Dewalt Driver. My door was metal so cutting was a challenge, remove the door, by far is the easiest, lay the door on two saw horses, template like the instructions. Just remember the template, does not take into account the width of the lip. Worked well and my fat cat is happy!!!

This was the only cat flap-door that was close to the size hole already cut in my cats' feeding-house so decided to take a chance because the vinyl freezer-strip I had ordered and put in during a warm spell between freezing weather had not preformed as advertised by seller. Thankfully they came during a nice Spring-like time and got them installed. I had to enlarge both openings slightly but not unexpected. the front sections were fairly easy to install, but I did have to remove half of the weather-brush strip on each door so they would swing a bit easier and not be too difficult for the cats to figure out how to use them Because the inside of the converted Rubber Maid storage container is not smooth I did not try to use the inner frame portion due to it being bigger opening diameter (designed to fit over the outer doors opening "lip". By the end of the day all of the cats had used the new doors although with a little trial-n-error. We are now getting a snow storm with drifting snow so I checked the doors after shoveling the deep snow away although neither door was covered by the drift. One cat; the most timid one, did not get through the door but rather waited for me to give her food, but so far the other cats have had no trouble using the doors. After installing the doors I removed the clear cling covering from the flap and tossed it away with the other refuse only to re-read the accompanying included and reading their cautions!! ATTENTION: please do not throw that clear cling covering away because they say to put it back on if the temperatures get below freezing to prevent the clear plastic door flap from breaking!! Guess I'll find out if that plastic flap will hold up :-( without the cling cover. The back cover section has two lines marking the depths one can cut down so it fits thinner doors but because the plastic is hard you would need to use either a skill saw or hacksaw but not sure how you would hold onto the frame piece while cutting because I think it's too brittle to use a vice to clamp it. Having another person hold it would be a big help. The bottom of the door flap has a weight in it to keep it hanging straight down as well as closed when a cat is not using it so a regular wind will not blow it open - make sure when you install the front door frame that you keep it LEVEL or the flap will not work!!!!

Just bought our second door. We use this on our garage door for our barn cats. Unfortunately some moisture got in and froze the lock this week and the door ended up breaking so I had to order a new one but these do a great job at keeping my barn kittens locked up at night and allowing them free roaming rights during the day. This is a great starter pet door.

Install was easy even though a cut out template was not provided. Quality is good and I like the 4 position locking option. The magnetic return of the door is a really nice feature too.

This is my second cat door. I bought the same one in August, 2022. The plastic door was cracked in half. I think I had an aggressive Raccoon. I took the remaining hanging plastic out so my cat would not get cut. I put a board block in front during the wait for the same cat door. I got the same kind as I had the proper size cutout in my wooden garage door.
The four setting rotating door lock would be better if the POINTER ARROW was in White as an accent from the four Black settings. It is hard to see and you're not quite sure of what position it is in especially at night where the garage lighting is sort of dim. Otherwise, I am happy with it. I don't like feeding all the neighborhood cats, raccoons, etc. so I can lock it at night.
