Carole, I'm so sorry to hear about Nikkita. I've been through this with my Storm and he even needed the PU surgery because he became blocked 2 times. He was on Royal Canin Urinary S/O both canned and dry and I would also add some water to the canned to give him more moisture. Now he's on a grain free diet and he eats mainly canned food with water added to it. So far he's done very well and the most important thing is that he loves his food. I hope that her new diet will help her. Lots of prayers and positive thoughts are being sent her way.
