We hope to provide a concept of "Internet of Things" for pet owners to have a daily monitoring. It mainly focuses on three kinds of devices - Food, Litter Box, and Water scale. The data that is collected by the devices each day and combined into a general data and monitor of any little changes of the cat’s health condition show within one mobile application. It compares and analyzes those data to help pet owners to more understand which helps to reduce the risk of any issues happening.The smart home devices will record the data about cat and notify owner, so it would reduce owner’s stress cause our device will be part of taking care cat role. The owner just needs to check the status by their phone . Also we hope the owner can establish a habit of taking their cats for regular physical examinations.
