NOT a hedgehog. Baby Echidnae: No, not a hedgehog which is an insectivore or a porcupine which is a rodent, but an echidnae which is a monotreme (lays shelled eggs). They live in Australia and New Guinea, where there are neither hedgehogs nor porcupines.
These female hedgehogs are solitary and might injure or worst, might kill their young when disturbed. It is highly essential to get rid of any cagemate and leave her and her young litter undisturbed for at least about 5 to 10 days after giving birth.
