I started out with 2 females, one normal, one a white lethal (blind, deaf, etc). They didn’t fight because poor Snowflake was dependent on Brownie for a lot of things and Brownie kinda took care of her.

After Snowflake passed, I got a young girl and there were no problems between her and the older Brownie. Once the new one hit puberty (Sweetpea) there were some small tussles, fights and chasing as Sweetpea tried to take over the Head Pig title, but Brownie always won out.

They would go through this every few months or so until Brownie finally gave in and let Sweetpea take over and now they’re very calm again. Being Head Pig just seems to mean Sweetpea chooses her lettuce first or drink from the clean water dish first…lol

If it’s serious biting, I would put a temporary divider in their cage just so someone doesn’t get hurt.

This is a site I’ve used a lot for trying to figure out what the piggies are doing, it’s got some tips for handling fighters and how to tell how bad the fight is.

I had four growing up, (four seems to be my number) initially one female, then another -both from the same litter though -the second female was my brothers that he gave me when he got bored. Then I bought a breeding pair (HOW I talked my parent’s into letting me breed?? and Keep the babies?!) that turned out to be both males.

I housed the two females together and the two males seperate, but my females were twice the size of the males-so we let them out all the time to play together. The males did not dare hump my girls.

I never had an issue housing the two females together-the first died at 6 , so they stayed together well after adolescence. I know that piggies generally like being in groups of at least two and generally don’t bite. So I’m puzzled.

I see from reading that article it may be similar to bonding bunnies-bathing them (stressing) to make them accept.
Is this piggie just going into puberty? I wonder if she’s simply hurt somehow or not feeling well-that may explain her sudden aggression.

Also-if they are just going into puberty-are you SURE you have two females? I just turned my friends children’s world upside down when I discovered their female guinea pig was actually ‘packing’

Hi Lisa,
We have 2 guinea pigs too, but they are both boys.

We were told by our vet that when they are more than 6 months old it is good to get them desexed because it stops them from feeling frustrated and fighting all the time for “top pig”

we havent had a problem with ours yet though, but will be getting desexed soon so that they dont feel hormonal all the time
