Lately she's been putting other toys in it like her mouse, so that way when she gets tired of chasing the ball she can take her mouse out and feel like she's accomplished something.
I know whatcha mean about the toilet! My cats are absolutely fascinated by the toilet! Every time we flush they are standing by, ready to jump up and watch the water swirl down! The tub, too. Every time I get out of the shower, I have to step over Jake who is there waiting to drink the water out of the sliding door track. EVERY DAY!!! These cats and their rituals, I tell ya!
