"healthy cats all raised on dry food would disagree with you."
As would all of the cats I've raised and the two current kitties! I do feed them a can of wet food at night, you should see the dance and hear the music when it's time for that!
Well I keep cans of the special AD around for my girl who nearly died. But its a treat, not her main diet. My other cats smell it and try to bury it! LOL.
