I had an interesting conversation with a friend who got a young Bengal female five months ago. They live in a high-rise and the cat is strong enough to open the sliding door to the balcony. They found her walking on the railing 12 stories from the ground one evening upon coming home from work. She plays very rough with their older cat and bites so hard she's injured him several times (sound familiar?) and she's also played rough with them. They decided to rehome her and found a good home with a yard. She only gets to go out on a leash, though. In her new home she's an only cat and has calmed down a lot.
