Laura beat me to it! Skinny Eliot gets his (regular dry adult) food only up on the kitchen counter. The two tubbies CAN get up there but it is usually too much effort. I feed the dieters their two 1/4 servings twice a day - same time as Eliot eats and then take the food away after about 15 minutes. I keep a bowl for Eliot in a cabinet and get it out now and then - up on the counter if he acts hungry - and stay with him. The tubbies acted like I was killing them for awhile but now they don't always even FINISH their food! (They eat SD W/D) Dylan is trimming down visably and is more energetic. Emily has only lost a few ounces but better than a weight GAIN as she is just now a year old. I am going to start feeding everyone the same healthy dry diet (not prescription) but continue to limit Emily and Dylan's amounts as they are piggies! Eliot will continue to get as much as he wants.
