I just had one of my cats diagnosed with struvite crystals, but no infection. Can someone give me a quick rundown of the %'s I should be looking for in both wet and dry foods so that I can look for something that is not the RX food once his crystals are dissolved. I got all the info here several years ago when one of my other cats had the same problem, but I have since forgotten what they are. Also, does anyone recommend any certain urinary acidifier over another? Vet sent me home with Methigel, but Bert isn't a fan, and getting it in him is nearly impossible. Maybe a dl-methionine in a pill form instead of a paste?
