A few day ago, my 22 lb Maine Coon cat jumped on my G5 keyboard. I yelled so loudly, he jumped on my Al 15" laptop keyboard. Sacred the heck out of as I am leaving for an important trip Friday and my laptop is critical. Fortunately, all that happened is that the G5's DVD drawer opened and the laptop's finder quit.
Needless to say I keep the door firmly closed. I am glad we don't have interior doors with lever-like handles. He reached up and tried to open the lever handled outside door but we caught him before he succeeded!
