What is the average lifespan of pet rats in a controlled environment?

1. 1-2 years

2. 2-3 years

3. 3-4 years

4. 4-5 years

The correct answer is: 3-4 years

The average lifespan of pet rats in a controlled environment typically ranges from 2 to 3 years, but it can extend up to 4 years with optimal care. This includes providing a balanced diet, a clean habitat, social interaction, and regular veterinary check-ups. Rats are generally known to have a shorter lifespan compared to other small pets, and various factors, such as genetics, health, and living conditions, influence their longevity. While other options suggest shorter or longer lifespans, those estimates do not accurately represent the common experiences of pet rat owners. In well-maintained environments with appropriate care, reaching around 3 to 4 years becomes feasible, underscoring the importance of providing a healthy and stimulating living condition.
