what treatments are you using????
I do HOPE you have her on canned foods and never dry for crystals...what type? struvite or oxolate? b/c a ph of 6.5 is very normal...its neutral and just where you want the ph to be so I'm confused...therefore can't be a struvite issue...I will send you some info and wait your reply...

I was wrong after doing some reading....a neutral PH is 7 anything below is acidic...but Dr. Becker states in her article a good healthy range is 6-6.5..
she also talks of a procedure with a laser called LETHOTRIPSY..that breaks the stones into smaller pieces so they can pass normally and avoid the need for surgery..
hope this helps
