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?
