I have a 17 year old female cat recently diagnosed with kidney disease, treatment is with a prescription low-phosphorous diet.
She is suffering with stiff joints, I am considering supplements such as glucosamine to help. But are such supplements suitable for her diet? I believe glucosamine itself is kidney-safe, but wonder about other additives such as salt or potassium which she needs to avoid.
Any advice on safe glucosamine supplements for a cat with kidney problems?
