Linus has always been a water-kitty. He's followed me into the shower from when he was the tiniest kitten. He does it to this day, sometimes I don't even notice until I get out myself and he's "drying himself" right outside the shower.
Last night was different. Last night, I ran my bath and walked into the kitchen for a minute (to get the stock pot full of boiling water, which I add to the bath, because otherwise I'd be sitting in water three inches deep and I prefer more, gah, this water heater sucks, etc) and came back to the bathroom to see Linus jumping out of the bathtub. For serious.
What a nut!
