I am so sorry to hear about your delima. I am so proud of my smart kitty, now how do I keep him in.

I don't know if this is possible, but may want to consider getting a couple of eye-hook latches (not sure of the exact name) and use them on the door. They are the ones that have a little eye that anchors to one side and a little hook that anchors to the other. if you use 2 or 3 of them and he should give up after the first couple that he figures out. I use these on all of our closets because our little Joey knows how to open the doors.

Good luck to your on solving the problems.
