Can I feed my cat too much protein?
If your cat eats too much protein, some will be excreted in the urine and the rest will be used as calories or converted to fat -
causing your cat no harm. However, if your cat has a kidney problem, high protein diets are not recommended.
Most pet food companies slightly exceed the minimum recommended protein requirements to ensure that cats
get adequate protein from their food.
Interpreting the pet food label This is where the hard part comes in. You now have two choices. The first is to buy a reputable quality brand of cat food for the activity level of your cat and hope that its needs are being met. This is what most owners do and the average cat does just fine. But if you have a cat with special protein needs or want to search out the best possible food for the money then you must dive into the label and try to interpret it. If you have been reading so far, you know that not all proteins are created equal. The listing of protein level on the bag or can is not a listing of the percent of digestible protein, just a listing of percent protein. So we need to know how to interpret the pet food label. We know that in quality foods digestibility is between 70 and 80%. In lesser quality foods the digestibility could drop to 60% or less. The way to determine the digestibility is not very scientific but is the best we have until the pet food industry begins to list digestibility. By reading the ingredients and noting the order that they appear we can roughly determine the digestibility. The ingredients are listed in order of weight. If the first ingredient is chicken or lamb or other meat, we can assume it is a good quality protein source. Meat meals such as lamb meal also provide quality protein. "Meat and bone meal" is an ingredient that is less desirable. If grains are listed, they are not as digestible sources of protein and contribute heavily toward the carbohydrate load. Some companies will list a meat source and then three different forms of corn, hiding the fact that the main ingredient is corn but just divided into three different products.
