My Lexie eats Excellence, by Virbac, it comes in hairball and digestive, no colourings, preservatives and good for UTI, she loves it, but tends to pile on the weight, the low cal version she is not keen on alas, Ash I have tried to get him to eat the good stuff, but he prefers his salmon pate and mince beef whiskas, he has Prime beef mince once a week as well,and biscuits as well, I tried him on the Royal Canin, a new one that helps cats not to have reflux, he liked that, and they have some optimin (sp) biscuits as well, ocean pilchard flavour, Ash likes them but Lexie is not so keen
