Innova EVO and urine

Does anyone know anything about effects of high protein/fat foods like Innova EVO for Cats/Kittens, and its effect on urine pH?

I know female cats don't get such things as often as males, but having worked in a clinic and seen the results of urinary blockage, I want to make sure my little girl has no chance of crystals.

I have her on Innova EVO currently but would like more info...does anyone have any contact emails for the company, also?

Are there any comparable foods you would suggest (eg high protein) that DO keep urine pH withing respectable levels? Thanks!!

Evo was feed tested so I would just email the company... in the past they have answered others questions regarding there products..

Natura (the company that makes Innova) has EXCELLENT customer service. I agree with Sharky, call or e-mail them with your question and I'm sure you'll get an answer promptly
