Have you read the ingredient list on your cat’s food? For any packaged food for humans or pets, that’s where you’ll get the most valuable information- not from the Nutrition Facts table.
What you want to see at the beginning of the list is real food ingredients that a cat might actually choose to eat such as chicken, fish, or beef, not by-products. And I can’t imagine that cats evolved to eat large amounts of wheat, soy, or corn.
After trying many dry cat foods, my current favorite is Core Wellness Adult Cat & Kitten Food. I don’t know whether it’s the turkey and chicken, small amounts of potato and tomato, or the probiotics (live bacteria), but my cat loves it (and he is as picky as they come) and his coat is softer and healthier than ever.
