Considerably larger than a hamster, Guinea Pigs have been known to be an excellent pet for children older than 10. While they do require more maintenance than some other beginner pets, their patient and friendly nature make them great starter pets for kids. They are very social animals, that require lots of attention and companionship. For this reason, they are known to do best in groups of two or three. Unlike hamsters, guinea pigs are diurnal animals, meaning they are active during the day and sleep at night. Therefore, their cage can be placed in any room of the house, including your children’s bedroom, without the worry of keeping them up all night.
