Another sign is her appetite; some hedgehogs may eat more than usual as they need extra nutrients for their developing young. You may also notice her being more reclusive or less active, preferring to stay in her nest.
If you suspect your hedgehog is pregnant, it’s a good idea to consult with a veterinarian who specializes in small animals or exotic pets for confirmation and guidance on care during her pregnancy.
Keep in mind that hedgehogs have a gestation period of about 35 days, so if you suspect she is pregnant, prepare for the arrival of baby hedgehogs (hoglets) soon! Make sure to provide a quiet, comfortable space for her during this time.
