I feed a mixture of a good wet diet and raw - natures menu 70% meat, hi-life 60% meat, tesco's finest 50% meat, Pets@home Nature 50% meat, Bozita and Cosmo (available from zooplus.com) 70% meat and Applaws. For raw try this company
Food4-Cats!, Just Food for Cats Nothing More! they do a great taster pack and the food is all sorted for vits, bone content etc so you don't have to worry - mine love it.
