I don't have a big house, it's actually quite small but I am surrounded by fields or waste land on three sides and my garden is fairly large aound an acre. On the 4th side about 50 yards away there is a busy road but the cats never go near it, I guess the noise frightens them away. I also have no problems with neighbours...my nearest one is a good 400 yards away and there are only 2 other houses within 3/4 of a mile.

Sounds like a dream situation - whenever I look at new houses the first thing that rules it in or out is if it is in a relatively quiet location so the cats can get out and about - I suppose its just a choice us catty folk make.
