Thanks for all your ideas! I think I'll try covering the counters with double sided tape on cardboard, and to give her a tall tree she can perch on with a view of the counters.
My kitten is 5 months old and recently discovered she is able to get up on the kitchen counters. We tell her not to go up, and take her down, but she jumps up again 5 seconds later, and continues to jump up over and over. It's difficult to get anything done, and a bit dangerous for her. How did...
