My nephew was Facetiming me yesterday, and he showed me that one of the cats did her business in the kitchen sink so they put her in a crate with a litter box so she "relearns" how to use it, so to speak. Which is understandable and hopefully it works. I would say at least 3 out of the 5 cats they have there go in places where they're not supposed to. And they usually clean the litter boxes there, which is fine and I don't mind doing it either. But if the cats go anywhere else, like the cabinet, or the kitchen counter, or the sink...they just leave it there and I'm left to clean it up. Which again doesn't really freak me out, but I wish I wasn't the only one who always has to do it. Like you have multiple cats, one part of caring for them involves cleaning up after them. But they don't do much cleaning period, and that's where I come in, whether I want to or not.
