My cat Ringtail (male, age 5 years) was diagnose with diabetes in Oct. 2017. He was put on .5 of ProZinc. His vet now has him up to 4.0 units twice a day. His overall health is good: stable weight, lots of energy, shiny coat, sassy cattitude. ( : But his numbers have more ups and downs than the Olympic HalfPipe event! Our vet advised me not to give the injection if he reads below 200. I've seen readings as low as 36, as high as 600+. Here is a 5 day sample: Feb. 11- AM 177 PM 252 Feb. 12 AM 431 PM 474 Feb. 13 AM 87 PM 536 Feb. 14 AM 362 PM 66 Feb. 15 AM 600+ PM 441 I am feeding FancyFeast Classic Pate twice a day, as well as 9 Lives canned tuna occasionally. I would appreciated any advice or input on the numbers, as well as feeding advice. Should he be fed smaller meals more often? Should I feed him "home-cooked" instead? HELP!!!
