Is my guinea pig happy or hates new brother?

[_leeexxie]

Hello!
I have one guinea pig (woodie) & recently bought a new one (coffee beans) because i read guinea pigs do better in pairs. When i introduced them i very quickly learned that woodie WAS A BOY. & get he became super aggressive. I had to seperate them in different room because he would not leave her alone & would circle her cage & try to get in. Hes about 7m & shes 2m. I dont know if shes scared of him or fond of him?

she tends to relax when i take her out of my room & then screams loudlyas soon as i open my door & i assume she hears/smells him? Advice?

To clarify, you think woodie is a boy and coffee beans is a girl? Have you properly sexed them yourself? You cannot assume one is a boy because of behaviour

If they are in fact one Male and one female then as you have done, they need to be kept separated

What was the aggression you described?
How did you introduce them to each other?

What you cannot say is that one piggy is aggressive - if they are opposite sexes, then it would likely have been an attempted mating.
If they are both in fact the same sex, then you still see them mounting each other - that is mild dominance, not aggression .
Equally, you cannot just put a new piggy into the existing pig’s cage as that is seen as a territory invasion and will produce aggression. All introductions have to be the correct way in neutral territory following the correct procedure

They are going to be able to smell each other if they are in close proximity and they will be excited by that. It’s their nature to want to be together. Equally though, as they are alone, then they will also be excited by seeing you - they will associate you with food.

If they are in fact one Male and one female:

Until he is neutered, they need to be kept separate to prevent pregnancy and you will have to ignore the noises. You will need to get Him neutered, then week for six weeks after the operation until he is infertile and then you can do a neutral ground introduction and bonding. If the bonding is successful, they can then both live in the same cage and will be much happier together. You will still see him circling her, mounting her etc, because that is normal behaviour but he won’t be able to get her pregnant and that’s the important thing!
