Guinea pigs are mammals so they give birth to live babies. The baby guinea pigs are called puppies. A sow (a girl) can give birth when it is 6 months old. Babies become adults at 6 months.
Guinea pigs do not eat meat. They eat fresh fruit and fresh veggies, like carrots, peppers, broccoli, beans and other leafy greens. They also like strawberries, apples, grapes, and melons.
