I don’t know, are they concerned about bladder stones?
“Phosphates are used as dietary supplements for patients who are unable to get enough phosphorus in their regular diet, usually because of certain illnesses or diseases”.
“Phosphate is the drug form (salt) of phosphorus. Some phosphates are used to make the urine more acid, which helps treat certain urinary tract infections. Some phosphates are used to prevent the formation of calcium stones in the urinary tract”.

Just a guess…. You could ask your traditional vet for his opinion, leave a message for him to call you back when he has a minute, just to ask him a quick question.

You may find that homeopathic vets and traditional vets often don’t agree on treatment modalities. Then you will have to decide which one you want to believe.
