Here's my two on the deck, about a month ago, maybe two. I had stained the deck about a week before that. They came and peeked in the window as if to say, "Hey! C'mon outside and give us a treat!"
I thought, gee, I hope they don't poop on the deck......I told Dave, "Don't feed then anything while they're on the deck, or this will become a habit for sure!"
