Newborn hamsters are very weak and fragile, so you must take care of them gently. Make sure they have a comfortable and safe space to rest. If the mother hamster is present, she may feed them; if not, you will need to find the right food to keep the babies well fed. Also, don’t forget to supply them with plenty of clean water. You may also want to visit a pet store and ask for advice from the salespeople or the vet on duty.
