Carole, I'm so sorry to hear that Lexie is still not doing well. I sure hope that she'll like the new Royal Canin diet. You may also want to buy some of the wet food too if she doesn't like the dry. My cats love it and I haven't had any problems. Now even my 6 month old kitten Ziggy seems to prefer it over he Nutro Natural Complete Care Indoor kitten food. It sure must taste good. I'll be keeping Lexie in my thoughts and prayers and hopefully everything will go well.
