Here are some ways to think about a guinea pig's domain:
* Physical environment: Guinea pigs are native to the Andes Mountains in South America. They live in grasslands, meadows, and rocky areas. This is their natural "domain" where they find food, shelter, and protection.
* Social group: Guinea pigs are social animals that live in groups called herds. Their "domain" might be the territory that their herd occupies and defends.
* Domesticated environment: As pets, guinea pigs live in a controlled environment provided by humans. Their "domain" would be their cage, play area, and the interactions they have with their human caregivers.
So, while guinea pigs don't have a "domain" in the traditional sense, their "domain" refers to the place where they live, the social structure they belong to, and the environment they interact with.
