Useful cat flap wall liners
These extension sections were handy for building the cat door through the external wall. They're good quality plastic

Expensive but do the job - I had to buy 4!
I bought this together with the catflap. It was difficult to calculate how many tunnel pieces I need as this was going in a 9” solid wall. I bough 4 tunnels which clip together, these ended up costing more than the catflap itself. The tunnels are expensive for what they are but do the job nicely and being plastic can easily be cleaned.

Fits the 304 model catflap
It was a bit expensive for a moulded piece of plastic, but completely necessary for fitting the catflap through a door. I chanced it and got it to go with the catmate 304 model and it fits perfectly.

Quality merchandise -cool 4 cats.
A great, reasonably priced product which is well made and looks great when installed. Our three cats seem happy and wondered why it was not fitted sooner.

It would have been better if there was a cut to size tunnel
It is expensive for what it is, especially as I needed six to go through a wall. It would have been better if there was a cut to size tunnel. There was a lot of packaging, as each section was in a cardboard box. That being said, it proved easy to fit with a compatible cat flap and our cat used the tunnel and cat flap readily which I thought might have been an issue. Despite my earlier comment this is a better and cheaper solution than fitting a cat flap in double glazing as that involves getting a replacement sealed unit with a bespoke hole in it.

Worked a treat
Needed to create a tunnel through a new kitchen extension. Worked a treat with matching ends.

Cat Flap
All as described but not ideal for going through cavity wall particularly access to lock and unlock. Also the manufacturers recommend a timber lining in the wall opening but the frames at each end are smaller than the timber lining which remains exposed, which is far from ideal.

£7.95 and £4 minimum to send back-!!-as wasn't required after all.
Great item-but we found it was not required after all-so selling on a well-known auction site as this would cost over half what I paid to send it back with Amazon-which is rubbish-!! **Be warned** tho'-no way could you cut this (or the matching cat flap) with a Stanley knife as shown on instructions-!!-it is way too thick-and you could severely injure yourself-!!-we ended up using a hacksaw/saw blade-and it was tough enough-!!

Closer Pets SPACER for wall door
I did buy two after reading the reviews, in our case we only needed one, this wall is actually accessing our crawl space, so maybe it isn’t as thick. It’s great! We’re happy with it cause our cat is happy with it. I just need to return one of them haha

Tunnel
De tunnel past niet bij het luik als hij moet op maat gebracht worden. Het frame is dan te dik en komt niet overheen het frame van het luik.

Doesn't fit the model 630 cat door.
Amazon likes to suggest this as "frequentely bought together with" the cat Mate elite chip cat door... Or what ever. Model 630. Problem is, they don't fit together, and so far I haven't been able to get hold of the correct tunnel extension.

Soddisfatto
Il costo del tunnel è elevato, ma mi ha permesso di risparmiare tempo di manodopera.

Túnel perfecto
Es un túnel para ampliar la gatera. Cumple con su función, la pena es que mis gatos tienen algo de miedo al túnel, y ha costado un poco que pasarán por ahí. Un poco de paciencia y todo solucionado. Ha quedado genial.
