Krazyaboutkatz posted in a thread I started about crystals in urine about a grain free food she feeds her kitties. I am looking into trying it for Morgan but right now he has to be on the s/d for 3 more weeks.

I'm sorry to hear about Morgan. My cat Storm has had crystal problems and has even been blocked two times before so he had the PU surgery. He used to be on Royal Canin Urinary S/O formula but is now on the grain free Innova Evo dry and canned food. He's been doing great and hasn't had any more problems since being on this food.
