I just began giving my two young Uaru romaine lettuce about 2 - 3 times a week. Yesterday they ate a big leaf and devoured the whole thing in about 15 minutes. It dawned on me that that is way more food than I ever give them at one time. Why would it be ok to have them eat that much lettuce, when I'd never give them that much flake or pellet - even veggie flake?
