I've had to have the girls (Chloe and I'm babysitting Sukoshi) gated in my bathroom, since we're having hardwood floors installed downstairs (my bathroom is as big as a small bedroom, so they've got it pretty cushy!). Then I went back to check on them after a few minutes, and they ATE MY WALLPAPER OFF THE WALLS!!
So just be careful if you have wallpaper and you want to keep it!
