Frequently Asked Questions
Indoor-only cats have an average lifespan of 14 to 18+ years compared to 8 to 12 years for outdoor cats. Outdoor cats face significant risks from traffic, infectious diseases (FeLV, FIV), parasites, toxic plants, and territorial fights.
Cats are masters at hiding illness. Subtle signs of aging include hesitation before jumping onto high surfaces (osteoarthritis), increased thirst or urination (kidney disease or diabetes), changes in grooming habits, or vocalizing more at night.
