Guinea pigs are surprisingly chatty little animals. They express their emotions through an impressive range of noises, from high pitched squeals of excitement to soft purring when they feel content.

Each sound carries a different meaning, helping them communicate with their owners and fellow guinea pigs. Listening closely to these vocalizations can help you understand what your furry friend needs or how they are feeling at any given moment.

2. Their Teeth Never Stop Growing

Just like other rodents, guinea pigs have teeth that grow continuously throughout their entire lives. This means they need to chew constantly to keep their teeth at a healthy length.

Providing plenty of hay and safe chew toys is essential for their dental health. Without proper chewing materials, their teeth can become overgrown, leading to serious health problems that require veterinary attention.

3. They Are Social Animals Who Need Companionship

In the wild, guinea pigs live in groups and thrive on social interaction with their own kind. Keeping a single guinea pig alone can lead to loneliness and even depression.

Experts recommend housing at least two guinea pigs together so they can groom each other, play, and communicate. Same gender pairs or properly introduced groups work best to ensure harmony and happiness in their living environment.

Unlike many other mammals, guinea pig babies, called pups, arrive into the world remarkably ready for life. They are born with their eyes open, a full coat of fur, and the ability to run around within hours.

This advanced development helps them survive in the wild, where they need to escape predators quickly. Watching newborn pups scurry around is an absolutely heartwarming experience.

5. They Perform An Adorable Jump Called Popcorning

When guinea pigs are extremely happy or excited, they perform an energetic leap into the air called popcorning. This joyful behaviour involves sudden jumps, twists, and kicks that look absolutely delightful.

Popcorning is a sign that your guinea pig feels safe, healthy, and content in their environment. Seeing your pet popcorn around their cage is one of the most rewarding moments for any guinea pig owner.

6. They Have An Excellent Sense of Hearing

Guinea pigs possess incredibly sharp hearing that allows them to detect sounds far beyond human capability. Their ears can pick up high frequency noises and subtle sounds that we cannot even perceive.

This keen sense of hearing helped their ancestors detect predators in the wild. Today, pet guinea pigs still use this ability to stay aware of their surroundings and respond quickly to their owner’s voice.
