Frequently Asked Questions
Indoor cats average 12-20 years, with many reaching 18+ years. The oldest recorded cat lived to 38 years. Indoor living is the single biggest longevity factor â it eliminates risks from cars, predators, fights, and infectious diseases.
Outdoor cats average 4-6 years due to risks: vehicle accidents, predator attacks, fights (abscesses, FIV/FeLV), toxins, and infectious diseases. Even indoor-outdoor cats have 2-3x higher mortality risk.
Keep cats indoors, maintain ideal weight (obesity reduces lifespan by 2-3 years), feed wet food (supports kidney health), annual bloodwork after age 8, dental care (linked to heart/kidney disease), and provide environmental enrichment.
