Yes, you can.
Yes, if they are neutered. Some people do this and the animals groom one another.
Yes. Guinea pig moms and dads will not eat their babies. They do not need to be separated from each other like hamsters do. The only thing you want to make sure of is that the dad is neutered or you will have more baby guinea pigs.
you shoudl not put a hamster and a guinea pig in the same cage no matter what.
you should never put a guinea pig with a chinchilla
you could put another guinea pig or they would probably get alond with hamsters or bunnies
You could... if you want to end up with lots of little babies. It IS possible to get them neutered and spayed at the vet, but the surgery is more risky in small animals than in dogs or cats. They also take lots of post-surgery care. If you don't have the funds or time for the surgeries, you could keep them in separate cages and put them together occasionally for a HIGHLY supervised playtime.
it really depends on the guinea pig, some get along fine with friends some don't
an animal may die if you do that. probably the guinea pig. :(
it means that YOUR guinea PIG LOVES YOU
No, guinea pigs should not be put in a guinea pig ball because they have delicate spines that can be injured by the rolling motion. It is better to provide a safe and spacious enclosure for your guinea pig to explore and play in.
When I got my guinea pig, we didn't know she was pregnant, so about a month later, my sister got one that wasn't pregnant. It was a little less that a month after that that my guinea pig had 2 babies. During that time, though, Molly, the pregnant guinea pig, was acting very territorial, and Milly, the non pregnant guinea pig, was staying by herself and not having anything to do with Molly. So make sure that if you put a pregnant guinea pig with a non pregnant guinea pig, that the non pregnant guinea pig is a girl, or else there WILL be trouble.
not necessarily; if you leave one guinea pig in the cage with the sick guinea pig, the guinea pig that is not sick can get sick; you should separate them just to be safe but if the guinea pigs start to get lonely, put them back together
