not ones to let pets suffer from unhealthy, tasteless food, pet food testers evaluate the nutritional value of pet food and, yes, taste-test it. pet food testers don’t spend every day sampling a cuisine fit for a pampered pooch, though (don’t worry, most pet food testers spit it out instead of swallowing it). most days, they’re writing reports and thinking up new ideas on how to put a nutritional spin on a new line of food. taste is important, but nutrition is the key to healthy pets.
