I Want And My Little Sister A Movie Chicks From Six That Is Good
My neighbor Totoro.
There are currently still some nice Studio Ghibli films on Netflix, so there's always the age restriction. You can also filter directly for kids, maybe this will help you.
For example, "The Kingdom of the Cats" is very cute, but at least you shouldn't be a total cat hater.
