Having a little issue my cat was not doing well on 1.5 units of Prozinc and his BG was 360. Was doing great at 121 for half a year now. However a fatty lump appeared slowly around the area where I inject and the vet said well never had this happen before but fat does not absorb insulin well. So he shaved some new infection sites for me and bumped it up to 2 units to get that 360 down Tonight he was at 83 on the two units and im thinking it needs to be back to 1.5 as it WAS the fatty lump stopping the insulin from doing its job. I need to inject him in a few hours and know I should get a vets approval before changing the dose but im not happy giving two units with a reaing that low. May just go with my guy and drop it down half a unit as he was before we realized the lump was an issue. Any thoughts?
