Review: Excellent cat flap - I originally bought an alternative cat flap based on my boys sizes and weights, but having fitted it, it soon became obvious that it was far too small. I don't think my boys are excessively large, they are Siamese cross and weigh 6-6.5kg. I genuinely did not believe they would need a large cat flap - but I was wrong. This cat flap is excellent quality and fits beautifully in our wooden kitchen door. Absolutely no draught gets through, but it is still easy enough for the boys to push. The locking mechanism could perhaps be simpler, but once you suss out how it works, it's no big deal. It's a very solid, quality item. My boys are 3 years old and had never used a cat flap before, with the exception of the previous purchase that was too small. Having struggled with that one, I wondered if it would put them off trying with this one, but the initial hesitance lasted no more than a few hours before they realised they could get through this one so much easier. I admit, the original cat flap was cheaper, but you can't put a price on your cats happiness, and it's not as if this was overpriced, it is worth every penny. Definitely recommended. Review: Good product for price point - replaces Cat Mate 221 model - To save confusion for potential buyers, this cat flap is exactly the same as the Cat Mate model 221 (White). What caused me some confusion is that the Cate Mate name is now owned by Closer Pets, who now manufacture the unit; the packaging says Closer Pets but the cat flap itself retains the Cat Mate logo and is exactly the same as the unit I was replacing, including the green and red sliding locks (and not blue, as some pictures indicate). If you're replacing an existing Cat Mate cat flap, it's very easy to switch by simply unscrewing the old one and screwing on the new one. If you're unsure what model you already have, this 221W has a cut-out size of 210mm wide by 227mm high and an overall size of 235mm wide by 252mm high. Note: depending on the thickness of your door or wall, there are 4 different screw lengths the instructions say you'll need to choose from to screw the unit to the door, of which only three sizes are supplied. (The un-supplied size is 25mm, which is what I needed. I've no idea why the manufacturers haven't included that size. Maybe it's the least needed size. Luckily I had four 25mm screws that fitted.) It's also worth noting that the unit has a fully brush-sealed flap with magnetic closure (my old unit must have originally been without a magnetic closure or had one that had worn off or been removed, so my kitties might need a bit of encouragement to push the flap a little harder). Build quality is absolutely fine for this price point and I have absolutely no concerns about its durability. ## Features - SECURE DOUBLE POINT 4-WAY LOCK: Offers in-and-out, in-only, out-only, or locked options, giving control over your pet's movements and keeping unwanted animals out - SPECIALLY DEVELOPED FOR LARGE CATS AND SMALL DOGS: Designed for pets up to a 360 mm shoulder height, such as cats, Yorkshire Terriers, Pekingeses, Dachshunds, and Miniature Poodles - DRAUGHT AND WEATHER-PROOF WITH SILENT ACTION: Fully brush-sealed flap with magnetic closure for draught and rain protection, operating quietly for minimal noise - DIMENSIONS: Self-lining to 50 mm thick for doors and thin panels; 235 mm (9 1/4") width, 252 mm (10") height; cut-out 204 mm (8") width, 221 mm (8 3/4") height - INSTALLATION MATERIALS: Suitable for UPVC, metal, and wooden doors, as well as walls, offering versatile and flexible installation options ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0002DHNJG | | Best Sellers Rank | 12,171 in Pet Supplies ( See Top 100 in Pet Supplies ) 32 in Cat Flaps | | Brand Name | Cat Mate | | Closure Type | Magnetic | | Colour | Brown | | Country Of Origin | China | | Customer Reviews | 4.5 4.5 out of 5 stars (7,036) | | Dog Breed Size | Small | | Frame Material | Plastic | | Global Trade Identification Number | 00035368202216 | | Included Components | all | | Item Type Name | Large 4-Way Cat Flap Brown | | Item Weight | 1.15 Pounds | | Manufacturer | PetMate | | Manufacturer Part Number | 221B | | Manufacturer Warranty Description | 3 years. | | Material Type | transparent | | Maximum Compatible Thickness | 2 Inches | | Minimum Compatible Thickness | 50 Millimeters | | Model Number | 221B | | Pet Type | Cat, Dog | | Size | L | | Smart Home Compatibility | Not Smart Home Compatible | | Target Audience | Cats | | UPC | 035368202216 712321846846 | | Unit Count | 1.0 count | | Weight Capacity Maximum | 75 Pounds | ## Product Details - **Brand:** Cat Mate - **Colour:** Brown - **Material:** transparent - **Mattress thickness:** 2 Inches - **Size:** L ## Images ![Cat Mate 4-Way-Locking Large Cat Flap (221) - Secure Lockable Door for Large Cats and Small Dogs, Easy to Install and Use, for UPVC/Metal, Wall and Wood, Brown - Image 1](https://m.media-amazon.com/images/I/71b1P8b0hCL.jpg) ![Cat Mate 4-Way-Locking Large Cat Flap (221) - Secure Lockable Door for Large Cats and Small Dogs, Easy to Install and Use, for UPVC/Metal, Wall and Wood, Brown - Image 2](https://m.media-amazon.com/images/I/71nf2y4ClZL.jpg) ![Cat Mate 4-Way-Locking Large Cat Flap (221) - Secure Lockable Door for Large Cats and Small Dogs, Easy to Install and Use, for UPVC/Metal, Wall and Wood, Brown - Image 3](https://m.media-amazon.com/images/I/71GYGpe2g-L.jpg) ![Cat Mate 4-Way-Locking Large Cat Flap (221) - Secure Lockable Door for Large Cats and Small Dogs, Easy to Install and Use, for UPVC/Metal, Wall and Wood, Brown - Image 4](https://m.media-amazon.com/images/I/71p-QgeubJL.jpg) ![Cat Mate 4-Way-Locking Large Cat Flap (221) - Secure Lockable Door for Large Cats and Small Dogs, Easy to Install and Use, for UPVC/Metal, Wall and Wood, Brown - Image 5](https://m.media-amazon.com/images/I/71DAUFaK5LL.jpg) ## Available Options This product comes in different **Color** options. ## Questions & Answers **Q: Is the cat door see through transparent like glass or opaque, my cat will not go through unless she can see what is behind the door** A: It is very clear, transparent, like glass. Not opaque (my old cat door was probably what you call opaque, like a haze or film over it; this is definitely clear in comparison). **Q: Will this work in an alluminum storm door? Our cat is 16 lbs will it accomodate his size?** A: The unit may stick out depending how thick the aluminum door is. I have it in a inside wooden door at a thickness of an inch and a half. It should work but it may not be flush on both sides. I would try though. As for the cat size, I've got 2. 20 / 21lb maine coons , they walk right through with no problem whatsoever. The only door I was able to find to accommodate large cats. Again, I would buy and try. Scot **Q: How big is the required hole in the door?** A: Thanks so much for answering my question... **Q: What are the exterior dimensions of this pet door.???** A: 9"wide x 9.5" long. That's the frame exterior. It works great! I have it on an inside door to my bedroom. I can lock them out when I want to sleep. Or let them come in for morning cuddle time. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent cat flap *by K***S on 7 May 2025* I originally bought an alternative cat flap based on my boys sizes and weights, but having fitted it, it soon became obvious that it was far too small.

In the end I removed the locks as I don't really need them anyway and I was too worried about them getting locked out. My cats are not very intelligent 🤣 however it only took 2 days to become fully fledged cat flap users, now there's no stopping them! I can't didn't fit this myself, I paid a builder to do it and it only took him about 30mins so it was pretty easy , but I don't have the knowledge how or the tools so I wouldn't have attempted it myself. It went easily into a composite door with moulded panels, he just used a really high quality silicone. ## Frequently Bought Together - Cat Mate Large 4-Way Cat Door for Large Cats and Small Dogs with Magnetic Catch and Durable, Rigid Flap - Brown - Cat Mate Wall Liner - Compatible with Large Closer Pets, Cat Mate & Dog Mate Pet Flaps 221 & 357, White (Pack of 1) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.mx/products/49290911-cat-mate-4-way-locking-large-cat-flap-221-secure](https://www.desertcart.mx/products/49290911-cat-mate-4-way-locking-large-cat-flap-221-secure) --- *Product available on Desertcart Mexico* *Store origin: MX* *Last updated: 2026-05-20*
