My current bot is fairly unfussy, but my first cat was addicted to fish and fishy flavours....he would eat lamb and chicken if there was nothing else going, but very reluctantly. The only other flavour we could get him to eat was beef - IAMS do some very good turkey, beef, lamd etc, and even my previous fussy boy preferred iams chicken to any other type of chicken. They also do tuna and salmon flavours, but the % isn't too high so should be fine for him. Hills science plan are also good. I've found that fussy cats will often happily eat any / all flavours of these makes of food, even when unbearably fussy with other brands. More expensive, I know, but better than them turning their noses up at it, and it's good quality, vet-recommened nutrition.
