Here's why:
* Sense of Smell: Guinea pigs have a keen sense of smell and use it to identify food, mates, and potential threats.
* Social Communication: They communicate with each other through scent marking, using their noses to detect and identify different individuals.
* Navigation: They also rely on their sense of smell to explore and navigate their surroundings.
So, while their noses might not be huge, they are definitely not small!
