I work from home, so I am very familiar with my cat's sleeping habits! The husband and I get up around 7:00-7:30 and let the kittens into the bedroom (we close the door so my husband can have the window open due to his mild allergies). They explore, and then Steve goes to sleep. Paddington and Conor hang out with us - playing and eating. They usually head upstairs between 9:30-10. Then, they all sleep until about 4 or 5 (when they then come downstairs to start asking for dinner!). Dinner is at 6, and after they eat and have a groom, they usually settle in for another nap - this one lasts until about 8 or 9. Then they play. They stay up until we go to bed (midnight-ish?) and then go downstairs and sleep until 5 or 6 (based on when I usually start to hear them running around!). And then the whole cycle starts over again!
