Pet's info: Cat | Domestic Shorthair | Male | neutered | 19 years and 2 months old | 9.5 lbs
Hi. tony eats Rx hills kd chicken kidney diet but in searching for different foods that I hide his daily meds in, i always look for a low dry matter percentage of protein and I’m finding that most senior 7+ diets at the pet store have more dry matter percentage of protein than the age 1-6 diets. Shouldn’t the 7+ diets be lower in protein for older cats with aging kidneys? am I correct in looking at dry matter percentage of protein when considering the kidneys? Thx!

Senior diets tend to increase protein as animals lose muscle mass as they age. You would do best to stick to diets formulated for kidney disease as they will take other factors into account such as phosphorus etc.
