So, one of our two-year old cats managed to tip over the dehumidifier we keep in the basement. It was full of water, of course. I've seen him use the dehumidifier before to vault up to a nearby dresser, so I'm guessing he pushed off with enough force to knock the thing over. But he's not even a particularly big guy. This is just the latest (and I'd have to say wettest) of his shenanigans. We've had cats for over 20 years and never had one get into as much stuff as this guy does.
