What to feed rabbits and guniea pigs that live together?

Sometimes you can keep a guinea pig and a rabbit together, they usually can be seen together.we have 2 female guineas and a male dwarf rabbit 2gether, although the rabbit has his own cage at night.

well yes you can because i have 6 rabbits and have recently had 2 Guinea pigs and we had no spare cages for them so we put the Guinea pigs in with the rabbits and they got along perfect.
