Contact a rehabber in your area if:

the animal is obviously injured (bleeding, vomiting, attacked by cat/dog)
the mother is known to be dead
there are flies around the baby and/or there are white/yellow clumps of fly eggs in the baby’s fur (especially around the eyes, ears, mouth, armpits, anus). These will hatch into maggots that will begin to feed on the baby.

If the baby has suffered no injuries and the mother’s whereabouts are unknown, do not offer the baby food or water, as these can harm the animal.
