I love our cat Rachael. She's been obese like me most of her life. I've recently changed her food too. Her dry food has been changed to 'grain free' and it's 40% protein. I give her significantly less dry food now though. She gets just a little mixed in with some grain free canned food and some water. I've already seen health changes in her. She is behaving as though she feels better and she's having healthier bowel movements, no more straining. I also switched her litter from A&H to Worlds Best.
