This is my greatest fear in having multiple cats. I have been so lucky over the years, but I have also done the unpopular thing of letting my cats come in and out at their desire. I only do that because we live in a very quiet area. We only have one cat, now, since we lost our 17 year old kitty in July, and he does not use the litter box, although it is there for him, if he is inside. He chooses to "go" outdoors and has never made a mess in our home in the almost 6 years that he has been with us (he was a stray that I took in).

I don't have much advice, but I sure would make it uncomfortable for any of those cats to be on my kitchen counters and table, especially if they are peeing on those surfaces. Can you shut off your kitchen with closed doors when you are not there to watch them? I have only heard and read, but using double sided tape, tin foil, and other things can discourage them jumping on the counters. I am not one that allows my cat to get on the kitchen counters or table, anyway, let alone pee on them. If he did, we'd be having a major discussion about it and finding ways to discourage that behavior. And I'm not sure that I could defend him well enough to continue to allow him free reign in our home. I'm not saying that he has never been on the countertop because I know he has and I have even photographed him there in the past, but I do not normally allow it and he knows it. If he tries, then one quick, verbal correction from me usually makes him get down.

I wish you luck. I know this is one of those awful situations that you simply must find an answer for. Unfortunately (or maybe fortunately), I have never been in your situation and can't offer much help.
