🐱 Cat aging formula: 1st year = 15 human years, 2nd year = +9 → 24, then +4 human years per cat year. Small breeds age slower than large breeds. Teeth eruption milestones help estimate age in kittens.
💡 Pro tip: Senior cats (11+ years) need biannual vet visits. Weight charts vary by breed; always consult your vet for personalized advice.
