I remember reading about 2 months ago that Friskies had changed their ingredient list, adding rice. That does increase the carb count, so I would probably avoid it as much as possible. Someone else may be able to address the specifics, or you can go to the Health forum and do a search for "ingredients" or "changing ingredients" and you'll probably find it. Good luck!
With Grayson, I learned that in order to eliminate all the different variables to see what triggered high numbers or low numbers (not that I ever saw many of those!) :lol: was to control the food - type and quantity. I logged that into my spreadsheet and was able to see patterns for food spikes. I also bought it by the 24 pack at Petsmart, so Grayson pretty much eats FF Chicken and FF Turkey & Giblets (both Classic pates). Every once in a while I'll give him a seafood, but he seems pretty okay w/ one variety. He had spent the better part of the first 6.5 years eating the same dry, so I guess it wasn't too much of an adjustment. Plus it was easy.
