My cat has been having a habit of dunking his cat toys in various things with water in them... the toilet, water bowl, a bucket in the basement that's catching a small leak from the hot water heater. He then proceeds to place them at various locations for us to find them. He puts them at the bottom of steps so you have to kick it out of the way, unwittingly soaking your foot because you didn't know it was soaked. He carries them around dripping so that there are wet spots on the floor everywhere. But his favorite place to leave them is on someone's bed. And the only bed that's normally available is mine. The rest of the doors are usually closed. So I've been finding wet spots on my bed with an accompanying cat toy nearby. Frankie is usually laying somewhere nearby also, looking proud that I found his present. It's getting annoying because I know sometimes it's toilet water.

And Frankie's normal look, which is why no one gets mad at him for little things:
Oh well, time to wash my sheets.
