They could be put into a cage together.
However, if there is a female guinea pig in the cage with them, that's not a good idea.
As they get older they tend to get more aggressive.
They will make plenty of babies unless u want them to have babies..& it is also gud to buy them together not to wait till they get older 2 put them together because they might not get alone.
Well, yes they actually can as long as they DO NOT FIGHT and as long as you make 100% SURE THAT YOU NEUTER YOUR MALES!!!!!!!! Also, only have ONE male if you have any female guinea pigs anywhere in the house. Please DO NOT breed guinea pigs, it is non-profit and so many guinea pigs need homes. I have two females who are not sisters but were together from a young age so they love each other :)
I wouldn't try to house them together as the guinea pig is going to get a lot larger then the hamster. It can be done hamsters can be put with guinea pigs. I had a hamster and a guinea pig together at one time because they were both alone. As long as you watch them a while when you first do it to make sure they don't fight then it should work out fine. I had a golden hamster i wouldn't try it with a dwarf hamster or anything that small. But as long as they don't fight and the guinea pig don't hog all the food then it should be ok. But if you have more then 1 hamster and more than 1 guinea pig i would not try it. THIS ANSWER IS CRAZY HAMSTERS AND GUINEA PIGS SHOULD NEVER BE HOUSED TOGHETHER. JUST BECAUSE IT WORKED ONCE DOES NOT AND I REPEAT DOES NOT MEAN IT WILL WORK OUT IN MOST CASES!!!!!!! This answer is horrible. No, they can NEVER be housed together. A guinea pig can only be housed with another guinea pig! do NOT put a guinea pig and hamster together, the guinea pig is going to get much bigger than the hamster. plus they need different foods. (MRS.TYLER22) Well first off i have 4 guinea pigs and 2 hamsters and for play time when i do not feel like letting them run around the room i put the inside of this really large plastic tote that i use to use to put my clothes in (very spacious) all of them and they just play in there together no fighting just playin but i do not allow them to sleep with the guinea pigs remind you that this is just for play time.Every animal is different you might just have to try your animals together on a trial basis because noone can say that they cant play or that they can every animal again is DIFFERENT!!!!
No way. They are to totally different kind of animals.
They might have a disease so you might want to get it checked out. After that you can put them together.
Well obviously, you cant have a male and a male giving birth could you!!
You can, but they will most likely fight, an probebly mate.
you cant make your guinea pigs mate, however if you leave them alone for long periods of time together they are more likely to. they may have already if they have spent time together and it could be early in the pregnancy when signs aren't as noticeable.
no guinea pigs cant eat peanuts
no they cant. they don't have the right nutrition that a guinea pig needs.
Nooo. guinea pigs cant eat pasta only fruit and veges
no, you cant cross a mammal and a rodent
They can not have cedar bedding because it has toxins in it that can kill a guinea pig.
You cant give cabbage to guinea pigs i dont know about gerbils.
