Well, we tried the laser, she has no interest in that either. Playing isn't her thing. Honestly, I am starting to think we have to accept that it's her world and we're just living in it, as an old friend used to say. She's happy howling, scratching on the door, running up and down the stairs and puking up random pieces of carpet or other things she shouldn't be. I guess she will live out her last months or years like this.
In the morning, she's become almost like an alarm clock. 7 AM sharp and she starts scratching the door.
