 CONT: At the beginning of the film, Milo is seen as a very young  kitten, perhaps three weeks old, nursing from his mother. When Otis  the puppy scrambles up to their nest in the barn, a curious Milo  topples over the side of the nest and the two animals meet for the  first time. Strangely, from the moment he topples out of the nest to  the moment when he lands next to Otis, Milo has aged at least a  month!
