Yes
If the cage is too small take it back and get a new one! Never get anything hamster for a guinea pig. If you have a small cage then that means you got a hamster cage.
You might see the guinea pig look around the cage and call for it. Whenever I take my guinea pigs apart the one that's still in the cage looks all around the cage and if he doesn't see the other guinea pig he starts squeaking.
You have to take care of it
You should just put it in a cage.
I would it will get very lonely and might get sick, my breeder told me. I have guinea pigs.
Then, you have to hand tame your guinea pig. You have to take him out of his cage to clean it, and he has to get treated for mite or he will die. So you have to just take him out and play with him all the time.
No, they wont harm the babies.
take it to the doctor
Take your guinea pig to the vet if something seems wrong...
First, take the guinea pig out and put it in a box or carrier. Use gloves and a shovel to deposite all the contents of the cage into a bin bag. Spray with pet-safe freshening spray. Wipe dry with kitchen roll. Take a lot of sawdust and sprinkle it around the cage. (fresh sawdust!) Take some hay and put it in the bed part. Put cage top back on. Put toys and food dish back in. Clip the water bottle on the side of the cage. Let in your guinea pig.
