Indoor cats typically live significantly longer than outdoor cats. The average lifespan of indoor cats is generally between 12 to 17 years , with many living well into their late teens and some even reaching their early twenties. Several sources highlight the average indoor cat lifespan as around 12 to 15 years, while others extend that range up to 17 years or slightly more with good care. Outdoor cats, in contrast, tend to live much shorter lives, averaging only about 2 to 5 years due to risks such as accidents, predators, and diseases. Factors that contribute to the longer lifespan of indoor cats include:
- Protection from outdoor hazards (traffic, predators, harsh weather)
- Balanced and nutritionally complete diet
- Regular veterinary care including vaccinations and preventive treatments
- A safe, stress-free home environment
Some breeds may also live longer than others, and genetics, diet, exercise, and preventive healthcare play crucial roles. Notably, the oldest recorded cat lived to 38 years. In summary, indoor cats generally live 12 to 17 years on average , with potential to live into their twenties with proper care and a safe environment.
