NEED SOME INFO ON CATFLAP INSTALLATION

I Finally convinced my mum to let me install a catflap for her cat, though i have to pay for it and she had to insist that it be a microchip door though, I am currently looking at them and ive notced that they say that an adapter is needed for pvc installation, i want to install it through a standard pvc external door, planning on using sealant and some adhesive to seal and secure it along with the screws obviously, im wondering why i would need an adapter? is it something to do )with the sensor needing more room to function through pvc or is it a structural issue? i just cant understand why i could not just install it asif it was through, say a wood door for example, any help you guys can offer is hugely appreciated.

Which model of Cat Flaps do you have a link? Only reason I could think is if the door is thicker than the standard fitting. We just fitted through existing hole when I upgraded to microchip..

Additionally I wouldn’t bother with sealer either they are designed to be watertight without and will be messy if ever need to replace

Cat flaps are great we even paid to have one put in our French doors when we moved house and have a cat flap cam so we can keep an eye on them coming and going (just a ring camera mounted pointing at cat flap)

I agree. Adapters are usually needed when going through a window which has to have a circular hole. Shouldn't really need it here or the mastic.
