The lifespan of small animals varies significantly depending on the species. For example, hamsters typically live for about 2 to 3 years, while guinea pigs can live up to 5 to 7 years. Rabbits may have a lifespan of 8 to 12 years, and ferrets usually live around 6 to 10 years. Factors influencing these lifespans include genetics, diet, and living conditions. Proper care, including a balanced diet and a safe environment, can help small animals live longer, healthier lives. Regular veterinary check-ups are also essential for monitoring their health and addressing any potential issues early.
