It is quite likely that an increase is warranted, but I wonder if you could get a few spot checks for a few days during the cycles, both am and pm before deciding to increase? At the moment all you have for information are the preshots, and getting a feel for how low the dose is taking the cat helps to determine whether to increase. With Lev, you may see later nadirs so even some spot checks between +6 and +10 can offer some good data.
