My cats love tuna cat food. A brand like Hilife has plenty of tuna in it, and a good strong tuna-y smell, plus it has the nutrients which cats need (unlike a tin of tuna from the human food department). Felix Good as it Looks is as Good as it Gets. Could be your cat's sense of smell is less strong as it gets older - I have two 10-year olds and one will take smelly food in preference to something more bland. My cats are very demanding at food time - could be she is just hungry, or... is she on a wormer? I agree with wolf, cats are opportunistic feeders. In our house, any human coming through the front door = must be teatime!
