Of all the product reviews that I wrote last year, I posted the most reviews about activity trackers. I wear an activity tracking device every day for two reasons. First, I like to see how many steps I’ve walked each day and two, I earn points that I can exchange for money through my day job. Money is always a good incentive to get active right? But what about our furry friends, how do we make sure they are getting enough exercise? With a pet activity tracker of course. The Petbit is a small device that attaches to your dog or cat’s collar, that will track their activity based on a points system (think Nike Fuelband). The Petbit features wireless syncing to a smartphone and is waterproof. The collected data will also display correlations between your pet’s activity and external influences like temperature or daylight. The Petbit will be available in March, but you can pre-order now for €79.99 ($108 US). So it’s not cheap and another downside is that it has to be charged once a week. A free alternative to the Petbit would be taking your dog for a walk once a day and chasing your cat around the house with a laser pointer.
