Guinea pigs originate from South America where the Moche people of Peru first domesticated them between 2500 and 5000 BC. Later, Dutch and British explorers introduced them from South America to Europe. You can still find guinea pigs in the wild in their habitats – forest edges, savannas and swamps.

In 1930 Dr Aharoni found a female hamster and her young in the Aleppo region of Syria. Hence the name Syrian hamster and all Syrian hamsters are descendants of that one female. Since them hamsters were taken into captivity for breeding and began to be kept as pets in 1945.

Gerbils originate from China and later Dr Victor Schwentker brought them to the United States for use in scientific experiments in 1954. Due to their interesting behaviors and cute looks, gerbils became very popular pets. However, gerbils are still being used in scientific research.


Guinea pigs usually live four to six years, but with good care your pet can live eight to ten years. A mature guinea pig is between four and six months of age. The best age to purchase a guinea pig is at six weeks, that is when a piggy can move away from the mother.

Gerbils live for 3 to 5 years and up to 8 years with proper care. In comparison to gerbils and guinea pigs, hamsters have a shorter lifespan – on average from 2 to 3 years. So, when choosing a pet for a kid, take into consideration which animal lives longer.


In comparison to gerbils and hamsters, guinea pigs are larger rodents that weigh between 1 and 3 pounds reaching from 8 to 12 inches in length. Gerbils are very easy to hold as they weigh only four ounces and are four inches in length.

Dwarf hamsters are much smaller in comparison to gerbils and guinea pigs. They weigh between 1 and 2 ounces at maturity and are up to 2 inches in length. On the other hand, Syrian hamster weighs 7 ounces and can reach up to 7 inches in length.

That is why gerbils make good pets for young kids who have little or no experience of handling a pet. Alternatively, hamsters are only suitable for older children. A guinea pig can be a pet for children 7 years of age with adult supervision.


Gerbils and guinea pigs are social little animals meaning that they need other of their kind around to be content. They are accustomed to being in groups. In comparison, hamsters are solitary animals meaning that you must keep it singly.

Although having two pets instead of one is more fun, you also need to provide them with a bigger cage and double of everything. So, for some owners the fact that Syrian hamster is a solitary animal is an advantage. However, hamster is not the only one rodent who can live alone.


A child can become a guinea pig’s owner if parents are willing to carefully supervise the animal’s daily care. That includes making sure that their food is nutritious, home is clean and comfortable. Furthermore, daily exercise is important as well as lots of love and attention.

Generally, guinea pigs, gerbils and hamsters are very clean animals. However, a hamster will store food in the cage and nesting box which will go moldy. Moreover, hamsters in comparison to gerbils, will pee and poop a lot, so daily spot-cleaning is a must.


Unlike hamsters and gerbils, guinea pigs are diurnal meaning that they are awake at the same time as their owners. So, piggies will sleep when you sleep! However, they can nap a little in the afternoon. In the wild, gerbils are nocturnal meaning that they hunt and move around at night.

Alternatively, hamsters are crepuscular (active at dawn and dusk). It means that they rest during the daytime and become active at night, dawn and dusk. It makes them a perfect pet for those at work or school during the day. You can play with them early in the evening.

Although guinea pigs are not as active as gerbils or hamsters, they do have certain characteristic moves and noises. You can even teach guinea pig tricks! Their noises indicate their moods. For example, purring means that your piggy is relaxed and comfortable.

Many owners get hamsters because they enjoy watching their pets explore the house and running in the hamster ball. That way hamsters stretch their legs and satisfy natural curiosity of their environments. Gerbils are also naturally very curious animals.
