Yes, I have seen numbers go up before a hairball, then come back afterwards. Though that's still a decent number for the AT meter. I would stay with this dose. Is it possible to get a before bed test at night? Many cats go lower at night. Other that the first cycle of the 0.1 unit dose when the 0.25 unit depot was still in play, I only see one data point to tell us how he's doing mid cycle.
