Try, but watch them closely. Many will fight.
It is generally not advised to keep two male guinea pigs together in the same cage as they may become aggressive and fight for dominance. It is recommended to keep a male and female pair or two females together to avoid potential conflicts.
guinea pigs
Guinea pigs only sleep for about 6 minutes a day, unless your hamster runs around 24/7 it wont keep them up.
With separate sides and protection
It's best to keep them in the same cage for about a week. And you have to put them in the same cage together for about and hour each day after that for a while. I have 3 male guinea pigs at home and usually the guinea pig who came into the family or home first will try to show the other guinea pigs who is in charge (Or dominant). It usually takes about a week to two weeks for the guinea pigs to work it out and become great buddies.
Because the male and female guinea pig would breed constantly and you would have a major explosion in the population of guinea pigs within a few months. Also, male guinea pigs can be fairly territorial and have sometimes been known to eat the offspring if there isn't enough room in the cage for all of them.
Put one in a different cage
Guinea pigs generally like their cage as it provides them with a safe and secure space to retreat to. However, it's important for the cage to be spacious enough to allow for exercise and enrichment activities. Regular cleaning and cage maintenance are also necessary to ensure their well-being.
Guinea Pigs are like any other animal, if you put a male and female together they will create little guinea pigs. If you want to keep the father in the cage, pay attention to the mother, she will let you know if she wants her space or if she wants him close.
No its not, i guinea pigs cage is way bigger. & you should not have the same size of guinea pig cage as your hampster.
your guinea pigs should already know the others male.if you want to breed then keep them alone for a while.
As long as you keep the cage clean then, "Yes." Use Aspen chips. You should especially keep it in your room if you only have one, as they are social creatures. If you get two get a male and female, with the male fixed.
