I don't have that many dishes, so I'd rather only wash them once a day. However, since the boys started jumping up on the counter, I haven't been able to let the dirty dishes stand in the sink, because they jump in there and then leave dirty paw prints all over. Finally today I got around to my project of cat-proofing the kitchen sink. I got some clear acrylic sheets ("plexiglass") from Home Depot, and cut two panels to fit over the sink. Now the boys can jump up there and look, but not touch!!
The other thing is that cats seem to be pretty uncomfortable suspended in mid-air. Tommy seemed to be somewhat put off by this new development. But I don't know how long that will last.
I cut it to fit quite snug just inside the raised rim; it's just laying there....I don't think there's enough for them to get a hold of to wedge a nose or paw under there and slide it off. I might get a couple cabinet pulls and screw them on there so it's easier for ME to lift up.
Thanks. I did have a slightly jagged edge on one panel because I didn't score deep enough. (It's pretty easy to sand smooth.) So anyone who wants to do something like that and hasn't done it before, that's my only advice: be sure you score plenty deep.
