Vocalizations:
* High-pitched chirps: These are often used as a greeting or to signal excitement. They might chirp at another guinea pig when they see them or when they're happy to be together.
* Whistles: These can be used to attract attention or to express alarm. A guinea pig might whistle to a companion if they are separated and want to be reunited.
* Soft squeaks: These can be a sign of affection or contentment. A guinea pig might squeak softly to a companion while they are grooming or cuddling.
* Repeated "wheeks": This is a common call used to communicate with other guinea pigs, especially when seeking attention, food, or companionship.
Other Behaviors:
* Looking directly at the other guinea pig: Guinea pigs will often make eye contact with their companions, especially when they are communicating with them.
* Tail wagging: A rapid tail wagging motion can be a sign of excitement and interest, especially if the guinea pig is also making chirping noises.
* Approaching the other guinea pig: If your guinea pig is moving toward another pig with a chirping or squeaking sound, they are likely trying to communicate with them.
Important Note: While these behaviors are good indicators, it's also important to consider the context. For example, a guinea pig might whistle in alarm if they are frightened, not just to call another pig. Observe the overall situation and your guinea pig's body language to get a better understanding of what they are trying to communicate.
Remember: Even if your guinea pig isn't "calling" another pig, it's important to provide them with plenty of social interaction. Guinea pigs are social animals and need to be around other guinea pigs to be happy and healthy.
