How long do rats live in captivity?

Rats' lifespans can vary depending on the species, their environment, and the care they receive. However, as pets, rats typically have lifespans of 2-3 years. Some rats may live longer, with some reported to live up to 5 years or more with exceptional care. To ensure a rat's longevity and quality of life in captivity, it is important to provide a suitable diet, ample enrichment, and regular veterinary check-ups.
