Hamsters are small rodents that have become a popular small house pet. When a litter of baby hamsters, also known as puppies, are born, the litter can range anywhere from seven pups to as great as 24 pups. After a male and female hamster have mated, it is common that the female becomes aggressive towards the males and may attack or even kill the males.

If, during birth, a female feels threatened, she may cannibalizes and eat her pups. After a litter of pups is born and is able to feed and drink independently, it is best to separate them from the mother as she may again cannibalize the litter.
