Your kitty may be needing more fiber, or a more gradual switch to the higher quality food, based on my experience with my dog (loose stools)
. It took her a month to adjust to the CS for dogs from Science Diet, and now she is doing great on Canidae (same company as Felidae
)-I switched her because she needed more oil in her coat and something that was more appealing to her appetite, and now she is shiny, muscling up nicely (she's a teenage Boxer -1 1/2 years old), and her stools are fine. I am currently switching my cats from Science Diet to Felidae Chicken and Rice, (one has a fish allergy that results in bladder infections
) but I haven't been using it that long and haven't completed the switch yet, I guess they have been on the mixture about 3 weeks, and I will continue it until the SD is gone
. Perhaps you could mix the Iams (as I assume you still have some
) and the Felidae, or CS, or the Royal Canin and take a long, gradual time switching to just the quality food that you want to feed, starting with mostly Iams and working your way towards mostly, then all, of the food you want them to have. I was pleased, though, with both foods for my dog, and my cats seem to like the Felidae just fine
PS- I don't notice the Felidae any more than the Chicken Soup(am feeding CS kitten to my foster baby-started it before I went to Felidae and didn't want to change), and while it may be a little stronger smelling, that is why my dog eats it better (she was a rescue, and needed to gain weight). I also haven't noticed it any more than the SD.
It is based on the idea that kittens and adult cats don't naturally eat differently once they are weaned, so we don't need to change that, just have better and more balanced, natural ingredients in the food we feed them. I know mine aren't totally on the Felidae yet, but their weight is still fine. If anything, they should eat less, because they are getting everything they need in a smaller amount of food. It's workin' for the dog
