after i've put additional cubes in between the cage to separate the two gp (one new one was introduced into the cage) because they keep making rumbling noises and chasing each other...ok, after i have done that, they both keep on biting at the cubes wanting to go to each other. im going to try and introduce them again tomrorow in an unfamiliar ground, but right now it's too late... it's dark. but why are they trying to come to each other? even the baby one wants to come to the big one (although the big one chases it).
