7am? I tried that, and they would still wake me up. I switched to evening feedings instead. My cats get fed at 9pm sharp. They only get one feeding per day and they usually make it last. That means there's still food in their bowls in the morning. It took them a few weeks to get used to it, but now we don't get woken up by the cats anymore. Well, they still jump on the bed and want a cuddle, but no more annoying crying for food.
