The auto feeders are excellent – mine feeds the monsters 4 times a day, including a snack at 4am so I get to sleep in until 7.

They stop begging you for food and generally sit and wait near the machine, only trying to take it apart or knock it off the counter if they are really hungry or bored.
It also has the benefit that it is controlled by my phone, so on the day when they need to be shut into their room for the cleaner to work in peace, I simply sit outside the door, trigger the feeder, watch them zoom into the room and close the door behind them, which saves chasing them around the house in an attempt to herd them.
