We discipline them with water bottles capable of squirting at long distance. We have four bottles stashed at appropriate locations around the house and could use more. Most of the time we need only show them the water bottle and they go scurrying away, only to return a few minutes later when they think we are not looking. We keep a cat-free bedroom upstairs for family members and friends with allergies. You can guess which room they are dying to get inside.
Any project is an invitation.
They especially love put-togethers or painting, anything that involves small parts they can run off with or something that will make a mess. Take a shower and you have an audience of two perched on top of counters or cabinets. Read the paper and they think it is a game filled with prizes for whoever can chew a hole in the lead story. Turn on a water faucet and they gather at the sink batting the stream of water until they are soaked. They have never tasted a bird, but they know it could be lunch.
