There's been some talk against the idea of an interspecies relationship and indeed even a family; you can't have that, it's unnatural, its an abomination, you shouldn't even think of it, the idea disgusts me, and (again) you can't have that. Baloney. Nick & Judy are cartoon characters (I know - they're too adorable, and their story is too compelling not to wish them real to me, also) and as such they can be anything (ties in with the movie, eh what?) and that includes parents. They should be parents! And their kids will not be weird or conflicted or defective, but they'll be cute (oops!; sorry, Judy) and adorable, like their parents, and they'll be a beautiful mix of bunny and foxy features, and it will all work splendidly.
