I got 2 female guinea pigs which are 8-9 weeks old 4 days ago, we have 2 of everything (hide, food bowl, water bowl) and they are in a 120cm cage. My concern is that one constantly chases the other one out of both hides and the other one does alot of high pitch squealing. The hides are placed besides each other. We also have a large cage run which we put them both in for a hour or so each day, but again one chases the other constantly. I have tried researching but feel that it isn't getting any better? Is there something I am doing wrong?
as said above the chasing and squealing are signs of dominance and submission. I would let them have a few days to sort out their hierarchy and then start putting them in their run again. You will most likely see the same behaviour in the run. Top pig just needs to be sure that the underpig has got the message. It sounds worse to us humans than it does to the piggies.
