Petscell is a cell phone that attaches to your dog's collar so you can stay in contact during those long days at the cubicle. Of course, if you want something a little cooler you could go with this. The damn thing costs $499, which is freaking ridiculous for the most basic cell phone ever (minus being waterproof), and doesn't include activation or service. It automatically answers calls from a list you set, so your pet won't kill itself listening to telemarketers. And now if you'll excuse me, I've got to call my bitch.
