Cat Mate 4-Way-Locking Large Glass Fitting Cat Flap (357) - Secure Lockable Door for Large Cats and Small Dogs, for Single/Multiple Glazing, UPVC, Wooden and Wall, White

Purchased this large cat flap for our West highland Terrier, self fitted into a newly ordered double glazed unit, works like a charm. Our 6 month old westie uses it fine, alongside our parents fully grown westies. I was concerned it would be too small for when ours got older, but seeing folks fit eased my mind.I personally worked for a glass manufacturer/wholesaler in the past so ordering replacement double glazed units based on customers dimensions used to be a common occurrence. It had also given me a fair amount of knowledge on how windows are glazed given common customer queries. This was the first time I'd ever popped a unit out and measured myself though. Most uPVC Windows are virtually straight forward to reglaze. Popped the internal beads out with a couple of flat headed screw drivers. Measured like for like replacement, knocking 2mm off the existing units sizes (most glass manufacturers work to a 1-2mm tolerance, I didn't want it any bigger), marked the glass where I wanted the centre of the hole to be, then with the beads popped off (the DGU virtually stays in place until you push it through from the rear allowing this) you can measure from the bottom of the glass to either bottom or centre of hole to give the location and diameter or radius of hole respectively to the fabricators.Cat flap fit the given hole size perfectly. Most awkward thing was cutting the oversized screws down to suit the unit. Fit the flap to the uninstalled glass unit, marked the screws, took it apart and sawed them down, then refit the flap to the unit, and popped it in the window frame snapping the beads back in place. Results are a great fitted Cat flap which works for us and our dog.The lock is a bit of a joke really. I mean, it's handy if you want to stop animals coming or going sure, but a person could easily unlock it from the outside.If you're looking to DIY it, it's fairly straight forward. Plug and play. Just be sure to be spot on with your measurements for the replacement DGU, as it would be quite expensive to order twice if you get it wrong. Although probably still cheaper or similar price to having it done for you even if you did fluff up.

Suits a large cat!!!I purchase the normal” size, had it fitted into a new glass panel - only to find my cat was too big/Fat!He’s a large, Russian blue and frankly, I should have known better!So, I purchased the larger model cat flap, new glazing for the back door - a very expensive error on my part but it’s perfect and both the cat and I are now happy!The moral of my story is:......if in doubt by the larger cat flap!It’s great quality, sturdy abd not ugly - would highly recommended

Really pleased with it. Feels really solid when fitted into the double glazed panel. Easy to install once you have the right sized hole in glazed unit. You need to be able to shorten screws according to thickness of glass and catflap. I had professional glazier make the glazed unit with hole and fit catflap. Works really well, the toggles are quite stiff but that means my cats cant work it.

Cat mate flaps are good quality.I had this fitted in a double glazed back door, you do need to have the glass panel replaced by professionals.My large cat is very happy, the door is see through with a slight tint. So he can see out.The only tiny complaint is the lock buttons are small and were stiff to move. A little oil and they’re fine now.

My cats are currently too stupid to have figured this out, but held or propped open they love it. Allows them in and out without having to leave the door fully open.

self locking metallic strip which stop the wind blowing it in and out - large enough for the cats to easily jump through - the only cat flap we found to go into glass when we blocked up the backdoor - hadn't realise we have to replace the double glazing unit as. you cut cut toughen glass . excellent product .

Excellent cat flap, most noticeable thing I find is how flush it fits to the glass pane on my door, a lot of the cat flaps I have seen stick out a fair amount which is pretty ugly. Great size too, 1 yo moggie has no issues coming and going. Had it more a few months now and on windy/rainy days noticed no draft issues... and at the price of 23 quid... 5 stars from me.

This cat flap is great! I have 3 cats ....2 of which are 7 kilos so i needed a large size. As i have climalit double glazing we had to order a new glass panel but it was quickly done and easy to install. The screws are the reason i gave four stars instead of five......they are extremely long and we had to cut them down a lot so they wouldn't stick out. The door however is great, on windy evenings it stays shut due to the magnet and little draught enters. My cats took two or three days to get use to it.....calling them with food helps!
