We lost a few socks this week. Gunnar is an opportunistic shredder. So, I put out a penny bottle setup for him. Sure enough, it didn't take more than a minute for him to spy the sock, and drag the bottle crashing to the ground. He left it alone until the next day, when he gave it another shot. Same result. It's been untouched for a few days now. Mary set him up with one of her socks hanging from the laundry basket. Sure enough, he went for the bait and scurried off when the bottle crashed to the laundry room floor.
We have a few bottle planted around the house, working on that extinction thing.
