I think one thing that might be factoring into the issue as well is that he and Casey since putting in the new shower curtain have been going in the bathroom after I shower and watching the water droplets running down the curtain (it's clear). I'm almost wondering if I should try going back to a non-clear shower curtain, which I haven't had since before the cats. It's just strange that the last clear one before I changed it out was never touched. Only difference with this one is that it's a little thinner than the last one.
Hmm, is there room for a second litter box in there? I know space can be tight in a bathroom, but one of them may not appreciate sharing that letterbox now? Did you change the kind of little or anything else?
