Hi I'm an engineering student at Olin College of Engineering. My team is creating a GPS Pet Collar that would cost around $30 and would sell online. We are currently prototyping different designs and would love feedback from knowledgeable pet-owners like you. So far, our product is a little black box that you attach to your pet's current collar. When you want to know where your pet is, look up your pet's location on Google maps. Are there any other features that would be important for you?
