Sometimes I guess things like that need to happen so they learn? My Miracle loves to rest on the top of her favorite chair. Where I used to live, it was pushed up against a wall, but now it's in front of a window, with a space between the chair the window (there's nowhere else to put it). When we first moved here, she jumped on the top of the chair when she got excited, went too far and fell off the back of the chair. I yelled her name, thinking she would be hurt, but she just walked around the side of chair...looked a little dazed, but fine. Hasn't happened again, lol.
