Thread: Maine Coon Milestones?

Longfellow turns 7 months old tomorrow, and this morning stood up on his hind legs and batted at a spoon on my kitchen countertop. It happened to quickly for me to take a picture, but I was amazed he is already tall/long enough to reach the countertop. What is next? By the way, does anyone know a good way to train Maine coons to open doors? I have lever-style door handles so it should be easy.

Thanks!
