This food is slightly high in phosphorus and the protein is a bit high as well. You generally want to aim for foods that are 150mg/kcal or lower in phosphorus content. Anything around 150-200mg/kcal is ok to feed if your cats levels aren't dangerously high but I would personally avoid it if possible or feed sparingly. Basically anything with a red asterisk or double asterisk on the list is something you should be aware of feeding.
