My cat has an incredibly sensitive stomach and throws up every once in a while after eating. I switched her over to the Authority cat food for sensitive stomachs, and she's been doing great. She still throws up every once in a while, but rarely, and mostly due to the fact that she'll eat too much too fast. Her fur has been softer, and she use to be so skinny and now I can tell she's gained some weight! I'm so glad I found a food that works for her and my wallet.
