I am not sure why Sox got the increase to 2.75 units. He got to 79 the cycle before the increase and was down in the 50's a couple days before that. I would have held the dose. I think he's bouncing a lot, and it could be from the steep drops. For example, the evening of 6/22, he went from 367 to 210 two hours later. A drop of 157 points in two hours will cause most cats to bounce. Sis might try feeding some smaller meals early in the cycle, say +1 and +2, to see if she can even out those drops. Some earlier tests in the cycle might show if he's doing more of those fast drops.
