According to ShinyShiny, the PetsCell features:
"GPS (so you can track your pet), an owner call button (so someone can alert you he's been found if you manage to lose him despite the GPS), and a speaker phone that will automatically answer if you call from a recognised and approved phone number (which will stop your dog from falling prey to telemarketers when you're out of the house)."
However, everyone will note that the product is only slated to be released as bone-shaped, which indicates that the target market is canines...or cross-dressing cats (zing!) That's ok...because, like me, BKP always screens.
(Oddly, both the PetsCell and the Wirefly Kids Cellie come with neck straps – unspoken hint or mere coincidence?)
