I'm looking into purchasing Wellness kitten food and I've noticed that the main ingredients after chicken are veggies like carrots and sweet potato followed by fruits like cranberries. There is also added salt. The claim is "Whole fruits and vegetables like blueberries, cranberries and sweet potatoes provide vitamins, minerals and antioxidants to strengthen cells and protect against free radicals that cause disease." I'm wondering if this is true at all? To my knowledge cats are carnivores and do not need anything else in their diet.
