:-) I think the cats need the lecture more than I do. Seriously though, the scientific community seems to be split on the subject. Cats clearly prefer outside for approx. half of the time, the other half eating and sleeping at home. I own a house with huge garden, doors are open, cats are where they want to be.
Giving them more activities to do and the greatly increased exercise are the two big ones. Even if you think it's better to keep a cat inside, there are strong reasons in either direction. People that let their cats outside aren't just being dumb.
