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
. 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.
