now I'm going to try and switch to Whiskas for a while and see how they react to that.
Whiskas has food dye in it and too much sugar. Cats on food like whiskas or Deli Cat often develope health problems. Diabeties, kidney falure, etc. Becareful feeding foods like those, they will cost you more in the long run, in medical bills. I feed my 7 cats Natural Balance and they do beautifully on it.
