Developed specifically for pets, this voice-enabled cell phone allows the owner to call and talk to his/her best friend. The waterproof 5 ◊ 2.5 ◊ 9.4 cm unit easily fits on a collar that goes around the pet's neck. The owner can also establish a geofence boundary in which the pet must stay. If this area is exceeded, the phone automatically calls the owner's cell phone or any pre-programmed number. Using the Global Positioning Satellite (GPS) sensor in the phone, the pet can easily be located. A built-in temperature sensor provides input regarding the pet's environment.
