kitties accidently had a self-training day

I have to leave every morning to go to work before Tim does, but then he gets home after I do. So I get home this afternoon from work and find that Tim has left the litter arrangement (the mixing bowl/sitz bath combo) out of the toilet. (We have to take it out when we need to use the toilet since there is only one toilet in our apartment). Sometimes when it's on the floor the kitties will try to walk in it, but since it is top-heavy they spill it. There wasn't very much spill which means they probably only tried briefly to walk in it and instead gave up. I found something else in the bathroom too... in the toilet was a yellow tint. Since Tim and I ALWAYS flush after using it, I just knew it had to be one or both of the kitties. :) I was excited, but I went ahead and put their "rig" back into the toilet for now. The kitties used the potty. Woohoo. :) And they didn't appear to fall in, either, because there wasn't a big area of water where they had splashed around trying to get out or anything. So exciting. :)
