This is not really any different than the few smokers/drinkers/junkfood-eaters that live to 90 while the rest of us that try to eat right have problems and such.

WE would all feel better if we ate right, but as long as junk(or easy) food is available, many won't.

I had tow females with diarrhea from brand name kibble and Spunky can't handle it so it is easier to feed well.

I was feeding Eukanuba (least offensive of the so-called premiums and the cats liked it) but sometime this winter, the critters truned their noses up at it, so I switched to VF formula, and Pinnacle. They really like the latter.

Scary part: in the bowl you can't tell the difference between Vf and Pinnacle. I am checking into that.
