Kitty will eat around it or will eat the dogs dry food if her food is messed with in any way. Anytime I've baked a whole chicken I've done my best to entice her with the organ meats. It's been a no go everytime!
Up goes her little black nose, up goes her long black tail as she turns her back on my pitiful offering of a special treat. She saunters past the eager terrier and the excited though elderly giantess with extreme disdain for their quivering noses and begging eyes. Once again royalty has put we commoners back in our rightful place.
I know how difficult cats are to switch, normally they do have to start out as kittens on healthy diet. Biggest difference between dog and cat, you can let dog go without eating, can't cat due to kidney's in cat will start to malfunction without food.
Our cat was fairly easy to change for some reason after she lost all her fur and I decided she was going to eat healthy. I don't know why she went for it, but she did.
