Well if you put them together in a cage they will mate or they could fight so, this is my opinion no I wouldn't unless you want them to have babies.
no because your hamster wether it is a girl or boy will hurt you guninea pig.
it depends what type of guinea pig you have
a guinea pig.
An Agouti is a large guinea pig type of rodent which may live in burrows.
If you get anotherfemale hamster the mother of the hammy they with fight and the female hamster will eat the baby hamster.! If you don't know if you have a female or male go to animal doctor and they will tell you if they female or male?
I don't think so. Hamsters cannot live with other hamsters, much less a guinea pig. Hope this helps
yes they can i have a hamster and she is quite happy.
A guinea pig would likely live longer.

a guinea pig they are more fun to play with for this age and live longer
A hamster is much more faster than guinea pigs. They are nocturnal, that means they are active at night. Guinea pigs are a little more "laid back and relaxed". But it really depends on what breed. Like, abbysinian guinea pigs are faster than your average American shorthair. Did you know, that hamsters can run in their little wheels up to 8miles at night! Hope this helped!
