Guinea pigs, scientifically known as Cavia porcellus, are small, furry rodents originally from South America. Their body size can vary but generally ranges from 8 to 10 inches in length. These adorable creatures weigh between 700 and 1200 grams. One of the most fascinating aspects of guinea pigs is their lifespan, which is unusually long for rodents, typically ranging from 4 to 8 years, though some have been known to live up to 10 years under optimal care.

The most unique organ of the guinea pig is its constantly growing teeth. Unlike human teeth, guinea pig teeth never stop growing throughout their life. This characteristic is crucial for their survival, as their diet primarily consists of hay, vegetables, and fruits, which helps in naturally grinding down their teeth. Without proper diet and chewable materials, their teeth can overgrow, leading to severe health issues.

Question: Why do guinea pigs make a variety of sounds, and what do they mean?

Answer: Guinea pigs are known for their vocalizations, which range from purring to squealing. Each sound has a specific meaning. For instance, purring may indicate contentment, especially when petted or held, while a high-pitched squeal might be a sign of hunger or excitement. Chutting is a sound of exploration or contentment, and a deep rumble, often accompanied by a sway, can be a sign of dominance. Understanding these sounds is essential for guinea pig owners, as it helps in identifying their needs and emotions.

Guinea pigs have distinct movement characteristics. They are not known for their agility or speed like other rodents but are quite active. They enjoy exploring their surroundings and can often be seen running in short bursts and performing small jumps known as 'popcorning', especially when happy or excited. These movements are essential for their physical health and mental well-being.

In terms of feeding behavior, guinea pigs are herbivores. Their diet primarily consists of hay, which helps in digestion and teeth grinding. They also consume fresh vegetables and fruits for essential vitamins. A unique aspect of their diet is the need for Vitamin C, as they cannot synthesize it themselves. Thus, supplementing their diet with Vitamin C-rich foods or supplements is crucial for preventing scurvy, a disease caused by Vitamin C deficiency.

Guinea pigs naturally inhabit environments that offer ample hiding spots and materials for nesting. In the wild, they are found in grasslands, rocky areas, and forest edges in South America. Their domesticated counterparts require a similar environment with plenty of space to roam, hideouts for security, and nesting materials for comfort.

Reproductively, guinea pigs are fascinating. Females can give birth to a litter of 1 to 6 pups after a gestation period of around 59 to 72 days. Remarkably, the pups are born fully furred, with eyes open, and can run within hours of birth. They wean off quickly, usually within three weeks. This rapid development is a survival adaptation, allowing the pups to fend for themselves in a relatively short time.
