Similar to Fitbit® for humans, this product is designed to keep track of an animals vitals. It also tracks their location and travel routes. The outer material is made of textured, natural rubber and slides over a standard collar. This material was selected to minimize the gripping of fur and to be flexible with an animal's movements. There is an LED panel on the device that can be turned on for pet visibility during night walks, but also serves as a battery life indicator and as an indicator for dangerous vitals of the animal, telling the user things like if the animal is too hot or has an elevated heart rate. This device typically sits on the back of the collar to ensure proper contact between the animal and the small nodes on the back of the device.
