Cat Mate2" Wall Liner

I decided to put a cat door through my interior wall, into a closet, for my cats to use a litterbox without the dogs eating scooby snacks (gross). Previously, I had purchased the pet safe cat door and installed it into an interior door, in my previous home. It worked well, no issues, but when I sold my home I was wishing I wouldn't have ruined the door with a cat door. This time I installed through the wall, as crazy as it sounds it would be cheaper to patch repair a wall then a full door replacement. So anyway- the flap that corresponds with this tunnel is really nice so far. My cats use it without issue (they are both tri-pods) and I am glad I listened to the previous reviews about getting two of the tunnels to go through the interior wall- it's a perfect fit! just buying one would not be enough. I would buy this again and highly recommend it.

We installed a cat door in our wall from the garage into the mud room. Because it was the thru a wall we had to have an extension for the width of the wall. It worked great!!!easy to install! Definitely would recommend!!

With 7 cats in the house, I got tired of opening and closing doors. So I set about finding a cost effective solution to my problem. Having read a number of reviews on different products, I settled on the Cat Mate cat flap Cat Mate 4 Way Locking Cat Flap with Door Liner White, primarily because of this wall liner, which seemed sturdier than most.We have fitted one external flap and 3 internal ones. My husband seemed to have no problem fitting them - the holes on both sides of the walls matched! It took 2 additional liners for each cat flap (so 3 in total, including the one we purchased with the cat flap. We have standard walls) and we stuck them together using superglue. I also sealed around the joint with a good quality caulk. Initially, I wasn't sure if they would hold up to all the wear and tear they were going to get - but they have proven to be sturdier that I thought. I just wish they produced a double width liner, rather than having to put 2 together. This is the reason for my 4 star review, rather than 5 stars.We have now had them in place for 9 months - and they have been extensively used (as you can imagine) by 5 of the 7 cats. The other 2 will use them if I hold the flap open for them. A couple of the younger cats literally fly through the flaps at full pelt and they have stood up to this absolutely fine. They also play with the cat flap - a cat on one sides of the flap leaning though and smacking the other one. I found that my next problem became being kept awake at night with them constantly opening and closing the flap - thank goodness for the lock!I have absolutely no complaints with either the cat flaps or the liner. The magnetic strip holding the cat door shut has been effective and we have no drafts coming into the house from outside.I would buy these again and recommend to anyone.

I needed to install a Cat Mate 4 Way Locking Cat Flap with Door Liner White (Model 235W) through an internal wall of my house. I resisted buying these wall liners for a long time due to their high price for what they are. I looked at all kinds of alternatives to buying these like bending sheet metal to act as the wall liners but in the end I ended up buying these to save time and to have a nice finished appearance. The item description wasn't clear enough for me to figure out how many wall liners I needed. I purchased a Cat Mate Cat Flap with door liner so I thought I may be able to get away with buying only one wall liner. However as others have mentioned in reviews you most likely will need to buy 2 for normal interior walls in US houses. This product appears to be manufactured in England so I guess walls there are thinner. I am rating this product 5 stars because it does what it advertises and appears to be built solid. The price is what it is and I ended up buying it so I can't dock any stars for it.I am mainly writing this review to provide missing specifications from the item description so people know exactly how many wall liners they may need to buy for their project. I wish Amazon still allowed customers to upload pictures because if they did I would upload pictures of the front and back of the product box which this Amazon item product page sorely needs to eliminate a lot of confusion. The wall liner arrives in a Cat Mate box and on the front it says it is compatible with the following Cat Mate Cat Flaps: 234W, 235W, 234G, 235G, 234B, 235B.If you purchased the Cat Mat Cat Flap without the door liner then you'll need to account for that. The door liner provides about 1.5 inches. With the Cat Flap model I purchased, 1 wall liner allows for a maximum of 3 1/8 inches distance from the exterior of one wall to the exterior of the other. With 2 wall liners the maximum distance allowed from the exterior of one wall to the exterior of the other is 5 1/8 inches. When you connect the wall liners you do so through a slot and groove system. One wall liner slides into a groove in the other and the cat flap slides into the groove of the wall liner. The depth of the groove is about 1/2 inch. So there is some play where you can sort of pull out a wall liner a little bit out of the groove to buy yourself 1/8 or 2/8 inches at each slot and groove connection. So if you have 2 wall liners you could pull each liner a little out of the grooves to probably buy yourself an additional 1/2 inch of depth [2/8" (wall liner 1 into wall liner 2 groove) + 2/8" (Cat Flap into wall liner 2 groove) = 4/8" = 1/2"].On the back of the product box the manufacturer lists how many wall liners they recommend for a given wall thickness. Here is the info from the back of the box:Wall Thickness - Liners Required*51-99mm (2-4") - 1101-149mm (4-6") - 2150-199mm (6-8") - 3200-249mm (8-10") - 4250-299mm (10-12") - 5* Use an additional liner for each 50mm of wall thickness

It didn't extend through the wall to the other side. My house has 1/2" sheetrock if you have 3/8 it might work through to the others idea and not leave the insulation showing
