Cat flap in paneled UPVC door

[sovietspybob]

I want to get a cat flap but our utility room door is a UPVC paneled type and i'm not sure the best way to go about it. In a flat panel fine but as the cat flap will span over the panels i'm not sure how to seal it other than liberal application of silicone and i'm worried about it not being weather tight or just looking botched.

This is the door

And this is a close up, the one i'm looking at needs an opening of 167mm so it'd just annoyingly be hanging over both edges

Also as one final thing i can't find a microchip catflap anywhere in any colour other than white or brown. As the outside of the door is anthracite grey i'll need to get a can of spray paint to make it look not terrible but that's by the by.

So any advise?

Hmm interesting thanks for the replies all, the thing is the door is in quite a prominent place on the house being the door on the left here so i can't have it looking pants

I had thought about putting it through a wall, i've got plenty of options to do that. It's a timber framed house with block outer wall so probably wouldn't be too big of a job. Don't know if you can hire those bore hole type drill bits for doing things like tumble dryer vents in a big enough size from HSS or similar as that could be a nice neat option to do that.
