Lol,my cat has never fallen into any of my tanks,I guess the lids have something to do with that.He does seem to like the flavor of the tsnk water as he has been observed on several occasions dipping his paw into the water through the opening in the rear and licking his paw.Just don't try that in Florida! They might end up as a gator snack... Would hate to see someone lose their furbabies that way.
