My two cats have been eating both NVI PRIDE and the Limited Ingredient canned foods for three months now. This diet instantly cured the problems my male cat was having; he would be miserably sick and throw up most every other canned food I tried giving him. I'll never know if it was the fillers, grains, gluten, carrageenan, soy or whatever else in the other foods that ruined his digestion...but I do know that Nature's Variety Instinct made him a happy cat from day one! My female cat loves all of the flavors I've managed to find so far, and has a softer, plusher coat. Both cats are so much healthier and energetic!
