That's the amount of time I get for initial results, but the REAL results come after a month or so. I think that the new food reacts to the old food that's still in the cats system, and you might get good results or bad results from that. Buffy and Willow were on Royal Canin and I switched them to California Natural a month ago. Buffy had lost so much shine on Royal Canin, which is why I switched. Buffy immediately got her shine back, and Willow was still acting frisky, and both cats were softer than silk. Now, however, while Buffy's still shiny, both their poops seem to stink a little more than they used too. I'm going to wait it out until the bag runs out, which should be in a couple of weeks, and if the poops are still stinky by then, I'm switching to Innova.
