How do you tell that a guinea pig is fighting?

Answer 1

Same sex mounting, chasing and standing on their hind legs and 'boxing' is all fine and part of them extablishing who is dominant.

If you witness persistent chasing where one gerbil does not stop to do anything else - such as burrow, eat, drink, chew or blood is drawn then you will have to separate. You must also intervene if you see your gerbils curl into a ball together and bite at each other - this can be fatal.

If you have to separate your gerbils they can only be reintroduced via the splitcage method.

Answer 2

It depends on who they are fighting with.

If they are fighting with you they may bite you hard, or refuse to get near you.

If the guinea pig is fighting with another guinea pig they will make a rumble like noise, and they also may stomp their feet.

Hope this helps!

Answer 3

If they're fighting, they'll be chattering they're teeth, fur at end and either nipping each other or hiding and continuously chattering their teeth.
