Time Disintegration

I have been working on teaching the kitties that they must sleep through the night as there will no longer be food left out for them and I will not get up to feed them in the middle of the night. This is mainly so that I can monitor Puff's intake as he must lose weight. Godiva isn't a problem as she's not overweight but she is a problem in that she apparently thinks she must have a few bites of kibble every 4 hours or so. As you can imagine, it's not so easy to teach 7 year old cats anything. I have managed to teach Puff not to holler during the night and that he can have a safe place on the bed but he must be quiet on the bed. This has worked out great. However, there is one problem with this in that he thinks I am the only one who has the power to enforce this "quiet at night and quiet on the bed" rule. When we are gone and my daughter takes care of the cats, he goes back to his old habit of wandering around at will and hollering.
We were doing fairly well with the training of sleeping through the night and no food bowls left out also. Daylight savings time did confuse them. I had gotten them to go to bed around 11 p.m. and not bother me until about 6 a.m. Daylight savings plan through them off key and they started bothering me about 5 a.m. This was still good though and a much improved time from the 2:30 and 3:30 a.m. feedings that Godiva, especially, used to insist upon getting. But again, it seems that I was the only one that could get them to "behave" during the night. I went away for a week and left them with my daughter, who dearly loves them also. BUT they somehow forgot all my hard work and started getting her up at 3:30 and 4 a.m. and demanding that they get food. She did not bend to their wishes but it made for a very short night of sleep for her.
When I got back, it seems that time has disintegrated for Godiva. She seems to be locked into the 4 a.m. time slot as her morning wake up call. She is not getting her breakfast until 6:30 a.m. but it still means that if she is awake at 4, then so am I. I am trying various techniques to overcome this and get her to stay quiet and asleep until around 6 but so far, no luck. Since we are currently and temporarily living in a one bedroom hotel room, there are a lot of factors that I cannot control, like the neighbor's alarm clock, the hallway noise, the cars passing, etc. I hope that these are contributing factors and eventually I will prevail over these small fuzzy animals with brains the size of walnuts. We shall see. In the meantime, I am getting a lot of stuff done on my computer in the early hours of the morning. Gotta look on the plus side for everything.
