At least yours just sits in the sink and wait.  Mine will push anything that
is on the counter into the sink until I come and fill it up for her.

As to the tub, mine stopped that after jumping into the tub while it was
still filled with ice cold water.  Now she peeks over the edge first, just
in case.

And I probably have one of the few cats who likes to drink out of the
toilet.  Had to stop using that blue stuff.
