I survived painting the 3rd floor by barricading the stairs. They spent all their time and energy yowling and trying to get through and managed to do so a few times. Our house is open concept so other than the bathroom and a small workroom there are no doors . They were none to thrilled to be kept out of the action as it took several days to paint everything. To show their displeasure they snuck up once and tore up the plastic drop sheet 10 by 50 feet and if that was not enough Maya peed on the pile they made with the sheets just to make sure I got the message.What should you do ? I really don't know. Next time I'm sending them to a kitty motel!!!!
