Pet stress patch clues you in on Fido's emotional health

Let's face it, being a pet in the modern era is pretty tough -- our furry friends live under constant surveillance and face crippling self-esteem issues brought on by a society hell-bent on upgrading them, and even replacing them outright with videogames and robots. Adding to the list of products designed to relieve Fluffy from these terrible burdens, Japanese outfit Medical Life Care Giken claims to have invented a patch to measure the stress level of cats and dogs. Based on studies linking sweat production to stress, the pin-sized patch goes on your pet's paw and changes color based on how much sweat it detects, allowing you to schedule doggie-therapy sessions accordingly. While we're not certain why it took a multi-year partnership with researchers at Toyama University to develop a sweat-powered animal mood ring, we only hope that Giken is hard at work on the fish and turtle versions of this patch -- it's been looking mighty tense in that tank.
