Your picture caused me to have a flashback of my Theo and Zoe (RB). They always used to come in and when the water was draining would walk around the tub fishing? or whatever. I ended up locking them out because I could not enjoy my bubble baths. They would bat at the bubbles and try to eat them and climb on to body parts sticking out of the water. You also knew that they were outside the door carrying on to be let in ,sticking paws under the door. It was years before they let me bathe in peace. My two new abys also like the tub but we keep the door closed now. They have enough places to wreck havoc and I still have my sanctuary.
