Back when I first started feeding grain-free cat food to Emily and Gryphon, there were not a lot of options on the market. Gryphon was fine on either a grain-free cat food or a healthy cat food made with grain, but Emily needed a balanced grain-free diet to ease her dry, itchy skin. I'm not sure what exactly she was allergic or sensitive to, but it was nice to get her back to her shiny, black-furred self. Nowadays, grain-free cat food is a readily available option for any cats suffering from possible allergies or sensitivities. The best part of this is that you are more likely to find a healthy, balanced grain-free cat food, made with quality ingredients that your cat will love.
Another plus to more pet food industry awareness of many cats needs for grain-free food, is that there is more info on what exactly grain-free means. At the time that I needed to get Emily on to grain-free food, I didn't think much about things that became diet issues as she aged like low protein, low phosphorus and low sodium. Emily did have a tendency to gorge herself so I did need to be careful of her caloric intake. But grain-free food does not mean carbohydrate free food; carbohydrate percentages can be similar in grain-free food as food made with grains. Something that seems to have changed since searching desperately for healthy grain-free cat food years ago is that grain-free food does not have to mean the food is high in protein, phosphorus or sodium. This is wonderful news for cats who need a grain-free diet but also may have other special dietary needs. The protein source in grain-free foods can be mainly from meat or vegetable sources or a balance of both just like in foods made with grain.
