[*]If your cat is green (0-99 human meter) at your normal test times, no need to test further until the next "PS" time, just feed small meals and go about your day. If the numbers are blue (100-199 human meter), feed a small meal and test again after about 3 hours. Food raises BG's. So if the number is lower 3-4 hours after a meal, then the pancreas is working!
