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.

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.

Great large cat flap but locking system not great
Whilst I love this cat flap for its look and price point and the fact it's big enough for my large ragdoll, I've taken a star off for the locking mechanism as I found my cats kept getting locked in or out as they were accidentally moving the locks when they were going through it. 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.

Easy to fit basic cat flap.
This cat flap proved easy to fit and works well. Comes with necessary fixings and can be locked in various ways to prevent access or only allow access one particular way. Unfortunately, my cat doesn’t seem to want to push it open himself, he just sits there looking out or in, waiting for us to open it for him!! We are working on that. We considered getting a more sophisticated sensor type model, but read that these can sometimes malfunction and lock the cat in or out, so went for the more traditional basic model instead. If and when he finally twigs he can operate it himself, this will be a great purchase.

Great value for small dogs too
From what I could tell, this is almost identical to the similar product for small dogs, but cheaper. We have a long-legged Jack Russell cross and she fits through the flap easily. The item arrived promptly, well-packaged and with clear fitting instructions. Fitting is easy. The scary bit is cutting the hole in your pristine door (I waited until my wife was out!), but it's easy with the provided stick-on cardboard template. Then it's just a case of holding the inner panel in place, marking the four screw holes with a pencil and drilling, before screwing it into place. The four-way locking mechanism allows; out-only, in-only, fully-locked, or fully unlocked. The tabs are slightly fiddly to operate, but work well. There is a strong magnet to hold it shut and soft bristles surrounding the flap to stop drafts. Our dog mastered the flap in about ten minutes, with the aid of a few treats. Although I can't vouch for its long-term durability yet, the product seems well-made and well designed.

large cat flap
Flexible Access Control The 4-way lock is very handy. You can restrict exit or entry depending on the time of day, guard against unwanted visitors, or fully lock the flap when needed. Good for households with multiple pets, or when you want to control cat traffic. Good Weatherproofing The brush seal and magnetic flap help with draughts and keeping out rain. The opening is large enough for many big cats and small dogs The 3-year guarantee is a plus. For what you’re getting good value for money cons i found the screws to be a bit small worried they come lose over time the locking tabs are only operable from the exterior, which may limit convenience or security

In het oude huis had ik dit kattenluik ook, mijn kat is groot en gaat hier gemakkelijk doorheen, de andere bleef in mijn oude woning en bij verhuizing heb ik deze opnieuw aangeschaft. Mijn kater Sam houdt niet van de klik van een luikje met een chip scanner en deze is gewoon handmatig te bedienen met en in verschillende standen .

Tengo esta puerta instalada en una pared de cemento muy gruesa que da al jardín. Como los gatos no tenían la costumbre de salir por ahí, tuve que quitarles su desconfianza dejándoles la puerta abierta y medio abierta por varias semanas hasta que se acostumbraron. Una vez que el primero salió y entró sin mi ayuda, el segundo hizo lo mismo. Ahora ya es su entrada y salida habitual. Funciona bien, es bastante silenciosa y no deja pasar el frío. Para mi ha sido una liberación y supongo que para los gatos también. Espero que dure mucho porque tuve que encargar la instalación a un albañil profesional y pagué mucho más de lo que costó la puerta. En paredes y puertas normales supongo que eso no sería necesario.

Wonderful item. My chihuahua and cats love it and I enjoy a cleaner house and not needing a litter box for the cats anymore.
