I am going to argue on one point of this whole thread... Precious and Spud are outside all day, with us going out at different times watering, feeding them and playing for a few minutes. Then, at night, we put the cats up and let them come in and have run of the house. Then, they are tucked away in their kennel for nite nite. They are perfectly happy well adjusted animals. I have just as good a bond with them as I do with Roxy who is strictly inside. Except for her bathroom breaks.
