What about a specialty item that allows us to freeze the age of a not-cat? I for one would love to keep one at young kitten age because the idea of tiny adventurers is so adorable
It might not be as easy, but it would be cool if you could choose which life stage you'd like to keep. And perhaps using the item once more could undo the perma-babying? I'm not sure what that item might look like, but probably something related to either time like an hour glass or maybe something related to age? Perhaps a magical seed?
