Depends on the size of the guinea pig and it's breed.
For two guinea pigs you need at least 7.5 feet of cage.

The adverage pet guinea pig will only reach about 35cm in length.
The guinea pig should see a veterinarian. The veterinarian can discover the cause of the guinea pig's hair loss, and he or she can see what should be done for the guinea pig.
you should never put a guinea pig with a chinchilla
you should probably brush your Guinea Pig for about 5-10 minutes
your should hold your guinea pig for about 30min to an hour each day
You can keep your guinea pig in a hutch or a cage.
Guinea pigs should always have hay in their cage. Feed them as much as they want. If you want to spice up their forage diet a bit, getting grass from outside (not near a roadway, sprayed with pesticides, or a dog's "bathroom" :). If your guinea pig is getting fat, I don't think it is because of the hay. Read up on what to do then, and if you want a second opinion ask your vet.
Yes because there is the after birth from the guinea pig
no, you should not feed your guinea pig beetroot leaves.
