A few weeks ago, my mom got new curtains for our living room. One window's curtains hang behind the couch, the others go to the floor and the kittens love this! They love to hide behind them and play 'attack' through them. they also like to climb halfway up the back of the couchthen bat at the curtains. how can I stop them from doing this? Tag even enjoys climbing inside the back of the couch...what do I do? I love my little girls, but they're destroying Mom's living room, and she's not too pleased.
