Answer
Hello,
I would actually buy them a play pen so they can frolic around they really need an area to roam more freely. Do you give them timothy hay? Guinea pigs need unlimited amounts of timothy hay. Also I'd consider buying them some chew treats for guinea pigs just to help them interact, but they need to be able to play outside of their cage to get exercise. The more room they have to run around the better. :)
