this is also a good site which lists cat food carbs, fat, and protein

a lot of good info on this site, which also states maximum carb counts and a bunch of other info for cats with diabetes. Talks alot about how a higher protein low carb diet benefits among other things.
As far as switching many say over a ten day period, start with 3/4 old food and 1/4 new food for 3 days, then go to 1/2 new 1/2 old food for 3-4 days, then 3/4 new 1/4 old food for the last 3-4 days. Watch your cats tummy, poop habits of course all the while, if anything seems to change, diarrhea, vomiting, may want to elongate the procedure even more. If there is anything severe, could be an intolerance to that specific food, and best to go back to the old instead of moving forward with the new, and trying a different brand. best wishes for snoopy
