I’m curious about grain free cat food. I’ve never thought about cat food in the past with other cats but my cat Zyla is the first kitty I’ve had since I moved out on my own and her health is important to me. I bought a grain free cat food today and I’m nervous she won’t like it. I feed her a combo of wet and dry. Does anyone feed their cats grain free? Are they a marketing scam or is their truth to how healthy they are?
