* Established bond: Guinea pigs form strong bonds with their cagemates, especially if they've been together since infancy. Introducing a new guinea pig can disrupt this bond, leading to aggression or stress.
* Social dynamics: Older guinea pigs may be less tolerant of new additions, especially if they're already established in their hierarchy. This can make the introduction process more challenging and potentially lead to conflict.
* Health risks: Introducing a new guinea pig can increase the risk of illness, as they could carry different parasites or diseases. It's crucial to quarantine any new guinea pigs before introducing them to others.
What to do instead:
* Get a bonded pair: If you want two guinea pigs, consider getting them together from a reputable breeder or shelter. They'll already be bonded and accustomed to each other.
* Introduce slowly and carefully: If you must introduce a new guinea pig to an existing pair, do so with extreme caution and patience. Use a neutral space and allow them to sniff each other through their cages before allowing direct interaction. Monitor them closely for signs of aggression or stress.
* Consider individual housing: If you can't introduce them successfully, you may need to consider housing them separately.
Remember: The well-being of your guinea pigs is paramount. If you're unsure about introducing a new guinea pig, consult a veterinarian or experienced guinea pig owner for guidance.
