I brought home two male guinea pigs on sunday and today one of the guinea pigs has started being very aggressive towards the other, constantly chasing him round the cage, swaying , chattering loudly and generally stressing the other pig out by attacking him. They are both around 12 weeks old, I am very worried about this, is it normal? At what point would it be considered excessive?
They have two seperate igloos and a fair bit of room to run around.
