i have two Maine coon kittens, 13wks and 15wks, both males. No matter what time we go to bed, no matter how much playtime we do before bed they are not able to stay sleeping. They wake up at random hours, and wake us up, usually by purring and general loving on us. I don't mind that as much because eventually they fall back asleep. However every morning at 5:52am they're up and crashing around. I don't mind it too much because I have to get up for work, but I have downstairs neighbors and I feel awful they chase each other around and I can't imagine what it sounds like to my neighbors. Is there anything I can do to encourage sleeping just a little later? If I separate them then they just cry for each other. If I put one in the carrying se, just for an hour, he cries like crazy and the other one goes crazy attacking the bag. Please help!
