what food do you use? If you are on WHiskas and generic supermarket dried she doesn't necessarily need sensitive fodd but beeter quality. Whiskas etc are packed full of stuff cats aren't able to digest properly. Try her on Hi-life (they have in in tesco's and not that much more expensive than Felix) and a better quality dry if she must have dry. I still give dry even though I don't like it a) becasue we have some left and b) my lad loves it (but it is addictive - I won't be buying any more). From what I hear about raw feeding many cats' and dogs' condition go away when fed a more naturla diet.
If you are already feeding a high quality diet then ignore my ramble and raspberry at me - lol
