Bests & Worsts Reviews from Amazon

I could not use the CAT DOOR in a door because to place the litter pans where I wanted them (storage closet under the stairs), I would have had to remove the door to my kitchen (closet door & kitchen door bump into each other). So, after reading every single question & review, I completely ignored the warnings and installed them in the wall (I was inspired by a couple photos). Didn't use the screws (Home Depot sold me some glue) and the brushes don't fit b/c of non-standard widths but I now have 3 size huge litter pans in the enclosed area under my stairs & no more kitty litter all over my laundry room. I painted the arches before installation and used some leftover (free) molding from HD to make a landing for the hole through the thicker wall (admittedly, it needs some "pretty-ing up"). All four cats adapted immediately (btw, I have 2 holes because one cat is a schmuck). The cutting template and the wood arches were well worth the price. I also added OxyLED Motion Sensitive lights (rechargeable version) to the under-stairs area so both the cats & I could see the litter (me to clean). 7/12/16 - I added interior photos that include rechargeable lights & litter pans (now missing and I can't add them back -why I do not know) 3/1/17 - I see a lot of questions re: installation through drywall. What I did: found studs. Taped pattern on wall btwn studs. Used super long skinny screwdriver and hammered holes along pattern (went thru both sides). Presented mess to husband and asked him to use his saw to cut along holes on both sides (if he had refused to help, I would have used a flat head & hammer to complete the break). Glued pre-painted "U"s on walls (both sides) and also glued free trim (there's usually a cart w/ that) from Home Depot below higher hole and as base in single thickness hole. Used flooring samples from HD as base for deeper hole (strongly recommended sanding and painting first ;-) . I've also glued flooring samples (in the wall - can't see) above the thick hole. Basically, I McGyvered it. If I had planned better it would have been prettier (still need to add more paint under the stairs) but the cats are happy & I am VERY happy not to have kitty litter all over the laundry room. 8/2/18 I now have 5 OxyLED lights in the area for max brightness. Always have an extra just in case b/c the female charging end is not robust & will push in & ergo become useless. I charge 1x a week (4 cats - much pooping). I use an Anker charging station (Anker is *the* quality brand for computer cables/chargers IMO). My essential cat products: 1) CatHole 2) Large ***white*** Pet Fusion cat scratcher. The big one. Absolutely essential. I have one upstairs and one down. Worth every cent. 3) Gigantic litter pans as pictured (I have 3 & bought 2 here) 4) Arm & Hammer multi-cat litter 5) Arm & Hammer litter deodorizer
