Each of my cats has a serious relationship with kitten kibble. I feed both of them from the same bowl. They used to butt heads over it, now they take turns. I feed them 90% adult kibble, but I sprinkle a little kitten kibble on top sometimes. They both love it, but Presta goes right to sleep after eating it, while Schrader gets a burst of energy like a three year old on a candy bar. They’re litter mates, but differ enough to bring up the question of more than one father.
