I'd posted earlier about Murphy not seeming to respond to his Prozinc. And, just like that, I got readings at 165 and 107 the other night. I cut back one of his doses by .25. Today, I had a reading at 537, which is so high that I immediately tested his other ear and got 388. I purchased a ReliOn meter today, too, and tested him PMPS, along with my AT meter. The AT meter showed him at 514, immediately testing again with a 509. I tested the second sample with the ReliOn meter, and it read 387. I am so confused about how he's bouncing so much. He seems to be feeling well- good energy- loving, etc. Any thoughts on causes for these extreme numbers? Thoughts on the inconsistent meter reading this afternoon? It makes me wonder how may times I may get inaccurate readings? Poor fella has bruised up ears from the last few days.
