1. We built a tower with a climbing ramp and attached it to the goats' play table. They enjoy high places.
2. Rowdy climbed up to the roof but he couldn't get down. That gave us an idea. Nowadays (unless it's raining and the roof is slippery) we let the kitties out the upstairs window so they can wander around the top of the house. They love it, and when they're bored they come to the window and we let them back inside.
