Our cat Soosh patrols the bathtub, marching up and down the rim when the tub is in use and often stopping to lap up bathwather.

As soon as the bath or shower is done and the water has almost drained, the cat jumps into the tub to decorate the bottom of the tub with dirty footprints while he slurps up more water.

He has actually fallen into the full tub or in-progress-shower several times, and seems to enjoy it when I cover him in bubbles from my bubblebath. He doesn't really mind being bathed, either.

I can't explain it. Some cats just like water, I guess?
