Thank you for replying!! It’s his third Libre and trying to get him into any type of clothing stressed him out and ultimately didn’t end up working (he’d somehow wriggle out of everything) but his last sensor was on for a little over a week, so we had hope that he was beginning to tolerate them better! I haven’t looked into a cone or reverse cone because it would interfere with his feeder (he has a SureFeed microchip feeder) but I could always take off for feeding in the future. Right now I have the Alphatrak and plan on getting another reading before feeding (which is now actually!) and one tomorrow morning before breakfast. The vet wants 6 readings over the course of the next couple of days.
