❓ Common questions
- How long do indoor cats live on average?
- Indoor cats typically live 12 to 15 years, though many live into their late teens or early twenties with proper care and checkups.
- Are outdoor cats aging faster?
- Outdoor cats face higher risks and physical wear, which reduces their life expectancy significantly (often to just 2-5 years) compared to safe indoor cats.
