What happens to your pets if something happens to you? Most of us have never answered that question. GreyLeash makes sure you don't have to — because the people who love your pets already know exactly what to do. How it works: 1. Add your pets. Names, quirks, feeding routines, vet info, medications — everything someone would need to care for them the way you do. Dictate it with your voice if typing feels like too much. 2. Add up to 3 trusted caretakers. Friends, family, neighbors — the people you'd want stepping in on the worst day of your life. 3. Check in with a tap. One button: "I'm Okay." That's it. Build a streak. Go on with your day. 4. If you ever miss your check-in window, GreyLeash automatically reaches out. Your caretakers receive an SMS with everything they need to care for your pets — no scrambling, no guesswork, no pets waiting at an empty door. Why GreyLeash: Peace of mind, every day. A hospital visit, a car accident, a rough mental health week — the moments we don't plan for are exactly the ones our pets need us most. Built for reality. Customizable check-in intervals (daily, every few days, weekly). Life doesn't run on a rigid schedule — neither should your safety net. Everything in one place. Feeding amounts, medications, vet contacts, behavioral notes, allergies, grooming preferences. A complete care guide that lives with you and gets delivered the moment it's needed. Pet care estate document. A shareable, printable record of your pets' care plan — the kind of thing you hope your caretakers never need, but will be profoundly grateful to have. Voice-first input. Describe your pet's routine out loud. GreyLeash fills out the form for you. Private by design. Your pets' information is encrypted and shared only with the caretakers you choose, only when it's needed. For people who live alone with pets, travel frequently, have complex medical or feeding routines, have senior or special-needs pets, or just want to know their animals are covered, no matter what. GreyLeash is available as a monthly or annual subscription. Unlimited pets, up to 3 caretakers, full check-in automation, SMS alerts, and the pet care estate document are all included. Your pets trust you. GreyLeash makes sure that trust is never broken.
