Kat - sorry, I did answer on the other thread.... no not yet, we have had several alleged sightings but either no cat there, or not ours. We are now in wait and see mode - rest assured that I will post if he wanders in.
I think I have raised a houseful of renegades though. No 1 son had surgery for a little growth on his back in the week, he's been getting stir crazy from being kept in. Yesterday I was woken up by next door's cat who could get in but not out again - today I came home early to take No1 to the vet for his post-op, and found that the cats had dismantled the cat door altogether - half of it was up the garden.
