Realistic Aging Model

Our model is calibrated so that an 8-year-old guinea pig (a very old age) equates to a 100-year-old human. This provides a more realistic view of their life stages compared to simplified linear models. Guinea pigs reach sexual maturity very early (4-6 weeks) and reach their full size by 8-12 months.

Pro Tips

Guinea pigs need daily Vitamin C as they cannot produce it themselves, just like humans!
A 1-year-old guinea pig is reaching early adulthood (approx. 32 human years).
Happy guinea pigs 'popcorn' (jump and twist in the air) when excited.
In Switzerland, it's illegal to own just one guinea pig because they are highly social and can suffer from loneliness.
Keep them away from drafting windows and direct sunlight, as they are sensitive to temperature changes.

Fun Facts

"Most guinea pigs live 4-8 years, but the Guinness World Record is 14 years and 10 months!"
"Despite their name, they are not from Guinea and are not related to pigs. They originated in the Andean region of South America."
"Their teeth grow continuously throughout their lives, requiring constant access to hay to keep them trimmed."
"They communicate using a wide range of sounds, including the famous 'wheek' (usually for food), purring, and teeth-chattering."
"Guinea pigs were domesticated as early as 5000 BC by indigenous tribes in the Andes."

Formula: Human Age = f(Months) where 1 month ≈ 12 years and 1 year ≈ 32 years
