What is the life span of rats?

• A. 1 year
• B. 3-4 years
• C. 5-6 years
• D. 3 years

Answer: (D)

Biologically, domesticated rats most commonly live about two to three years. With excellent care, some can reach around three to four years, but five to six years is not typical. Choosing three years as the best answer reflects the most common, single-value lifespan used in everyday care and teaching about pet rats. The option of 1 year is shorter than usual for a healthy pet rat, and five to six years exceeds what’s commonly seen. A range like three to four years is possible, but when asked for a single lifespan value, three years best represents the typical expectation.
