Bru(bleep)e Crystals

pmomci Aug 29, 2009 01:21 PM

Our two ten yr. old male Burmese cats both had surgery for bru(bleep)e bladder stones recently in spite of changing to all wet urinary foods,Purina St/Ox and Walthams SO pouch. The smaller cat at 7 lbs. had calcium oxalate stones removed a yr. ago and that was when the food switch was made. Looking for how to prevent both these stones. Your input very much appreciated.

Calcium oxylate stones develop in acidic urine and struvite crystals develop in alkaline urine, so you want to keep the urine in a 5.5 to 6.5 pH range. The easiest way to do that is to feed fresh meat. Cooked or raw chicken, with its bones, along with some cod liver oil and plain yogurt is probably the cheapest and easiest way to feed a cat. Be careful about adding any supplements, as they may change the urinary pH.

Thank you for your reply. Does your advice apply also to the brush-ite crystals which I understand to be calcium hydrogen phosphate dihydrate?
