Here's an old post with a response from Weruva: http://www.felinediabetes.com/phorum5/read.php?8,1539050 They claim that their foods, even the ones in gravy, are very low in carbs. FDMB members who have fed Weruva have found that some varieties do affect bg levels. The one low carb variety I occasionally fed to my diabetic was Mack and Jack which was chunks of fish in jelly. Paw Lickin Chicken is a questionable one. The starch in the food affects bgs in some cats but not others. The new Weruva Cats in the Kitchen pouched foods are in gravy so are not suitable for diabetics.
