You should never handle a wild animal because it stresses them and can spread disease, but it’s entirely a myth that a mother will abandon her young because of unfamiliar smells. This is not true of any animal species. If you, or a child, already handled a baby animal and it is not hurt or orphaned, put it back where you found it (and call your doctor if you were bitten or scratched). The mother will return for her baby, even if she isn’t nearby right now. A mother’s love is stronger than the scent of a human hand.
