The overall aim is to maintain the phosphate concentration in the lower end of normal range: <1.45mmol/l.
IRIS (International Renal Interest Society) specify exact targets for each stage of CKD (two months post-start of treatment).
CKD Stage 1: 0.81-1.20
CKD Stage 2: 0.81-1.45
CKD Stage 3: 0.81-1.61
CKD Stage 4: 0.81-1.94
For all cats with CKD, the vet and owner should aim to:
- increase the cat’s fluid intake
- manage the diet with renal diet and/or phosphate binders
- restrict phosphorous, which will improve quality and quality of life
- use anti-hypertensive treatment if cats have increased blood pressure
- consider ACE inhibitors in cats with proteinuria (UPC>0.4)
- employ symptomatic treatment of any other complications
