Yeah i don't see why not. But check them reguarly to make sure they don't fight, if they do separate them, but they might just get along fine, as guinea pigs are a sociable creature and prefers to be with others there own kind rather then alone.
Yes, you can. Males can live together successfully but keep in mind, each Guinea Pig has its own personality and will get along with some but not others. Pairing a dominant with a submissive pig is a good idea. Adoption rescues do have pairs for adoption usually. Also, make sure they can't smell or see females which the results of most male fights that have been together without issues for months is females.
It depends on whether the male has been neutered (If you want babies or not). If he has, then I think you can keep them together. Otherwise, the females my try to fight over the male (and vice versa, two males may fight over a female). If you do want baby guinea pigs, then keep one male and one female together. You should not keep any less than 2 at a time, but I think you could keep 2 males and 2 females.
Yes most of them can, as long as the cage is big enough (not a store bough cage - those are usually way too small) and they've been properly introduced - on neutral grounds. It works better if one of them is an adult and the other one a young piggy.
if you want to
It appears that no they cannot
guinea pigs and chipmunks should not live together.
I have been told they will fight if living together.
because guinea pigs are aggressive
You can put rabbits and guinea pigs together. But I think that's all
There are several reasons why you shouldnt keep guinea pigs and rabbits together, the rabbits are usually bigger than the guinea pig so there is some danger of the guinea pig being injured and although its rare, guinea pigs and rabbits have been known to mate which can harm the guinea pig and even the rabbit.
yes you can they'll love it.
I disagree and know that Guinea pigs are very social animals and need the company of other guinea pigs. Social animals that live on their own get stressed and lonely. Litter-mates of the same sex should live together, as this minimises the chance of their fighting. Males and females shouldn't be kept together, as they will breed and it can be difficult to find homes for the young.
No, they tend to fight.
With separate sides and protection
I have tow male Ginny pigs an i keep them together and they are fine.
No, these animals should not live in the same confined space. this could cause harm to either the guinea pig or the hampster.
No, they don't have to be the same age to live together.
