This could simply be the dominant piggie reminding the other who is in charge. She may also be in season and doing her mating dance. If there is no actual fighting or bickering then they should be ok. When my girls are in season they rumble and strut around each other. The 'in season' piggie then chases the other around the cage trying to mount her. Not very ladylike to watch!
