How Long Do Pet Rats Live in Captivity?
WouterThe life span of a pet rat varies depending on breed and care, but an average lifespan is two to three years. Rats will live longer in captivity if their conditions are optimal. However, most pet rats will not live this long regardless of care and attention.
Rats can be difficult to introduce, especially those that are over a year old. While many rats are happy and accepting of a new companion, some are very antisocial and set in their ways. This can make it difficult to get along with your pet rat. You should also be prepared to deal with any behavioral issues your new pet may have.
Older rats are much like older humans, becoming less active as they age. These rats also suffer from similar health issues, including weakened muscles and body weight. They often develop arthritis and show other signs of aging, such as a slow gait. A rat that is four to five weeks old will no longer be dependent on their mother for nutrition and will fend for itself, though it may still depend on its siblings for social interaction.
Stress in a rat’s life can cause significant problems. While rats are highly resilient when faced with infrequent but stressful circumstances, prolonged exposure can cause depression and PTSD. Other stressors that can affect a rat include moving from a different home or changing its cage. Another factor is the loss of a cage mate or a human carer.
