I became a "Cavy slave" in January. I adopted 2 very cute brothers who were about 1 month old. They have been together ever since they were born. I built them a nice big C & C cage with all sorts of toys. We noticed in the beginning one always mounting the other, which we figured out was a dominance thing. That quickly diappeared as they matured. Everything seemed to be going just fine as they adjusted to us and their environment, Suddenly within the past 2 weeks they have been chattering their teeth at each other and today one actually showed his teeth at the other. We have put a divider in their cage

(the wire that the cage is made out of) for fear that they may hurt each other. Where do I go from here, keep them divided forever? We attempted to take the divider down for a bit and the chattering started again. Any suggestions would be greatly appreciated!
