Now that the kids are back in school it means quieter days for my cats who really enjoy the calm after the craziness of summer. Not every cat is the sleep-all-day type of cat, though. There are some who take a cue from our kids and all their homework and want to increase their brain power. Some like to watch educational television shows, some concentrate on biology, and some just love to hit the books. - By Devan McGuinness
