Your pet can't tell you how they're feeling. PetKit helps you notice. Log walks, meals, weight, symptoms and vet visits in seconds, and see your dog or cat's health at a glance — so you spot changes early and walk into every vet visit with the full story. YOUR PET'S HEALTH AT A GLANCE Pin the cards that matter to you: activity, weight, meals, water, sleep, a health log and more. Every card shows the last 7 days, and you can switch between pets with one tap. SPOT CHANGES EARLY Charts that fit each metric show weight trends, activity compared to last month, and highlights like "daily average is up 15%". Track symptoms such as vomiting, itching, coughing or loss of appetite, and see how often care routines like baths and nail trims usually happen. LOG IN SECONDS Search any event, pin your favorites and pick up from recent entries. Forms remember your last values, and a long-press logs the same thing again. Measure heart rate by tapping along with your pet's heartbeat. NEVER MISS A DAY Turn on a gentle evening reminder to log your pet's day, and get notified before vaccines expire. ALWAYS VET-READY Keep a digital vaccination card with clinic details and expiry dates, plus a full history of medications, vet visits and treatments. BUILT FOR REAL PET LIFE - 35+ event types: walks, hikes, swims, meals, water, sleep, potty, weight, temperature, heart rate, grooming, flea treatments, deworming and more - Calendar and timeline views of your pet's history - Dogs, cats and multi-pet households - No account needed Some features, including detailed charts, full history and multiple pets, require PetKit Pro.
