About This Launch
Enter your dog or cat's age and see it in human years. Size-based charts for dogs (small to giant, AKC/AVMA guidance) and the 15, 24, then +4 rule for cats, plus FAQs on senior age and lifespan. Free, no signup.
Why I Built This
Built after watching friends guess their pets' ages by the 7-year myth.
