This is Noir's take on the whole thing. I expect him to to live a long and happy life sleeping underneath the couch.
We did put up the baby gates just to see what they would do. Besides, it is great fun to torment them. We have one genius cat who only took minimal motivation to jump the gate. Noir is valedictorian of the class. What was his motivation you ask? That he was in the same area as the other 2. Eli is a little slow and still has not jumped the gate.
