My husband was watching tv and saw Ripley mosey across our front porch!!! He went out and got him. Apparently, he opened the screen (they slide open) in the play room. We keep our windows open quite a bit when it is nice outside. Any suggestions to keep my Houdini from escaping? Does this mean he is unhappy with us? Does he need a friend? More play time? (he has 4 people that play with him quite frequently) He tends to just stand at the doors and meow or look out forlornly. I feel bad for him but it is way too dangerous around our house to let him outside. Thanks for any suggestions!
