The cats were never really outdoor cats. So this summer was the great experiment. I let them out on the deck to roam (supervised). Willow is still shy. (He was left outside in the heat one day. Sorry!) Everyone else likes a little outdoor time. Patch eats grass. In a previous incarnation he was a cow. The grass is growing as a weed in one of the containers. He’s fine with that. Everyone else likes the fresh air too.
