Seems very palatable
I have 2 sixteen year old cats, one of whom had renal failure. Bought this as vet said specialist renal diet might help turn his kidneys around. It was a qualified success - I tried all 3 RCV formulations as renal cats can be very fussy eaters. They ate it, but it was least popular of the 3 RCV varieties.
Can't comment on efficacy for renal support, as Kaspar died from kidney failure within a few weeks of my purchase.
