Social Hierarchy:
* Establishing dominance: Guinea pigs are social animals that live in hierarchies. Fighting can be a way for them to establish who is the dominant pig.
* New introductions: When you introduce new guinea pigs to a group, it's important to do it slowly and carefully to avoid conflict.
Environmental Factors:
* Lack of space: If guinea pigs are overcrowded, they may fight over resources like food, water, and territory.
* Lack of hiding places: Guinea pigs need places to escape from stress or conflict.
* Dirty cage: A dirty cage can cause stress and aggression.
Other Causes:
* Illness or injury: A sick or injured guinea pig might be more irritable and prone to aggression.
* Hormonal changes: Female guinea pigs can become more aggressive during their heat cycles.
What to Do:
* Separate the fighting guinea pigs: If they are fighting, immediately separate them to prevent serious injury.
* Introduce them slowly: If you're introducing new guinea pigs, do it gradually over several days.
* Provide enough space: Ensure your cage is large enough for all your guinea pigs to have their own space.
* Provide hiding places: Give your guinea pigs places to hide and feel safe.
* Keep the cage clean: Clean your cage regularly to avoid stress and illness.
* Consult a veterinarian: If the fighting is severe or persistent, it's a good idea to consult with a veterinarian to rule out any underlying medical issues.
Remember: Guinea pigs are sensitive animals, and it's important to understand their needs and behaviors to ensure they live in a happy and healthy environment.
