The patent pending PetsMobility?? PetsCell TM will be compatible with existing cellular and satellite GPS technology. The PetsCell?? will allow pet owners to talk to their pets as well as allowing owners to request assistance should they become incapacitated and require help. In addition, and perhaps more valuable, pet owners will have a piece of mind that if their pet is lost and someone finds their pet wandering the streets, with a simple press of a button on the PetsCell??, the auto dial function will dial the owners home alerting the owner to retrieve their pet.
While on vacation, at work, or on the road, pets can be contacted by that friendly recognizable voice of their owners.
The PetsCell??, 2-way communication device will also be available with an optional GPS tracking chip and a fibre optic camera for search and rescue applications.
