Pigs don’t like to live alone, but if they aren’t already a bonded pair, you will have to follow specific instructions to introduce them to share a cage. Generally, jumbo cages don’t provide enough space for what is required for guinea pigs. Google the needed square footage depending on how many pigs per cage you will have, as well as their genders. Then, see if the pen you are looking to use will be large enough. If not, I recommend a C&C cage.
