I have litter trays in the kitchen, cat room, bedroom and bathroom (and have had them in the living room too), to be honest the kitchen one doesn't bother me, as it is a good 4 feet away from where I cook (well, when I cook of course!!), and scooping trays is one of the first things I do when I get in, so nothing in it while I am cooking. The one that does annoy me, and the one I would like to get rid of, is the one in my bedroom, nothing worse than being woken up at 5am by a cat digging for mad, and then the smell. I dislike getting up anyway, never mind that early!! I dont have a prob with worktops, I have lazy cats that dont bother with them, although one of the fosters has started doing, but all he does is go on them to sit on the windowsill, so can cope with that. As I have bad habits of stroking them and not washing my hands (esp at night), then I am sure if I was going to get anything, it would have happened by now, have been doing that for nearly 5 years.
