When my cats were younger and fussy I made the mistake of feeding them Fancy Feast. Now they are all senior cats and I have been trying for years to get them to eat better quality foods. I've used every trick I could, adding a little to current food on the side so they get used to the smell, mixing a little bit in to current food, being very patient about it....the only thing that came close with one cat is putting toppers on like freeze dried chicken or Bonita flakes, she'll pretty much eat anything then, but that doesn't work for the others. Do you have any unique suggestions or can you explain why it is so difficult to get them off Fancy Feast so others won't make the same mistake?
