Duncan and Smudge have been on a diet, but this trend started waaaaay before that. Duncan and Smudge are if nothing, excellent measurers. They can tell if they have been fed less than a desirable amount and are quick to protest.
Tonight I gave them half a can of Fancy Feast instead of the typical one can each, thinking that they could get a second helping before bed. But their little sense of measurement took charge and a protest was quickly organized.
