The Solitary Lone Hamster

All rodents, mice, rats, and some species of hamsters are sociable creatures. Most will live happily together in groups or pairs in the same or opposite sex, and most may form a bond with one another and their owners, rats especially.
The only exception is the Syrian hamster, these are by nature solitary creatures just as nature intended them to be.
The Syrian hamster will fiercely defend his territory against intruders of his own and other species.

Even in captivity this instinctive / innate behaviour of the Syrian hamster still persists.
Just because the Syrian hamster has been domesticated this does not mean we can change their instinctive behaviour. Domestication will not change the instinctive nature of any animal.
The Syrian Hamster is the most popular of the rodent family to be kept today as pets.
Some of the Dwarf hamsters may quite happily live together, some even raise their young together.

Syrian hamsters are different, being of a solitary nature they prefer to live alone. They come together only to mate, and only then when the female is in heat. The female raises the young pups on her own, the male has no further contact with the female or the young once his part in the mating is complete.
Syrian hamsters are not social animals and must not be kept with others of their species or other species after reaching adulthood. At around 6-8 weeks of age the Syrian hamster must be housed alone and kept that way for the rest of their natural lives.

A female Syrian hamster that was once so protective of her young should be separated from the young pups no later than 5 weeks after the birth, after this time she may become very anti-social with them.
Any adult Syrian hamster that comes into the vicinity of another adult will almost certainly end in an aggressive fight. Why do they fight?

But the solitary nature of these creatures does make it much easier to keep just one as a pet.
The Syrian hamster is very attractive and comes in several varieties of coat and colour variations. It is both cute in general appearance and in their day to day activities.

Some people say the Syrian hamster is unfriendly unsociable, and even evil.
That all they seem do is eat, sleep, play, and could not care less if they ever saw a human.
Let me assure you that is not the case, the Syrian hamster if, and when tamed properly are sociable with humans. They are very friendly and will take a great delight in interacting with us.
Some people think the Syrian hamsters do not make good pets for children. Let me also assure you that the Syrian hamster makes an ideal first introductory pet for children. It helps in educating them into responsible pet care and ownership.

Any animal, be it a rat, cat, or dog, that is mistreated or ill treated will turn out to be an unsociable animal. The Syrian hamster is no exception.
