Low-protein cat foods are made to help cats with kidney problems. Chemicals created after digesting proteins can be difficult on the kidneys of cats. Low-protein foods don’t cure kidney failure in cats, but they help the animals feel more comfortable. Low-protein cat food is available in either canned or dry formulas. Some of these foods are also low in sodium and phosphorus, which is helpful for older cats. These foods are expensive, so they’re not made for use as a general food for any cat. You should consult with a veterinarian before using them. In fact, some low-protein cat food brands only may be ordered with a veterinarian prescription in hand.
