Have 3 set feeding times per day. Put the food down, with them separated by a closed door. Set the timer for 10 minutes (so you don't forget them!) When it rings, pick up the left overs, and put it all away behind closed doors; doors which THEY can't open.

I feed in the morning when I get up, at 4 PM, and before I go to bed. I use 3 bedrooms, a bathroom and a hallway! If I can juggle 10, I just KNOW you can work it out for 2!
