[quote user="Martin Atkinson"]Did anyone make a diagnosis/perform a PM examination on the cats that died? [/quote]

Unfortunately no PME was done.

Sorry if I wasn't clear, there are only 2 cats, one died, one still going. Ultrasound examination was performed and there was no polycystic disease, there was however an increase in the cortex:medulla ratio.

[quote user="Martin Atkinson"]Also that BUN and Crea seem a little low to me especially with a normal phosphate to be the result of primary renal disease[/quote]

Urea and creatinine were 38 and 554 initially and phophate was 3.76. Both cats FIV/FeLV negative.

[quote user="Martin Atkinson"] I think you need to get the owners to commit to some outlay here and do the additional tests and renal ultrasound/biopsy. The future is not rosy for this kitten given the familial history you are likely to be damned if you do and damned if you don't so I would take a fairly conservative approach if they won't pay for the tests.[/quote]

The owners have already spent quite a lot on both these cats, and given the poor prognosis, they are understandably reluctant to spend lots more given that it is unlikely to live for long (has lost 1kg since last year).

I had a case where 2 cats in the same household (can't remember if they were siblings off the top of my head) got renal lymphoma secondary to FeLV. They were euthanased about a year apart.

Also that BUN and Crea seem a little low to me especially with a normal phosphate to be the result of primary renal disease. I would start looking outside the box here. Agreed with a previously normal Ca less likely to be primary hyperparathyroidism causing the renal diseases but I'd still look at previous diet. And how about lymphoma - OK unlikely in 3 cats but they are related. Have these cats been FeLV tested?

I think you're on a pretty sticky wicket giving calcitriol in this case until you've proven its renal but equally giving prednisolone and or frusemide is tricky if it is renal. I think you need to get the owners to commit to some outlay here and do the additional tests and renal ultrasound/biopsy. The future is not rosy for this kitten given the familial history you are likely to be damned if you do and damned if you don't so I would take a fairly conservative approach if they won't pay for the tests.
