I would think that the pred dose is supposed to be .15 ml at each of
the two dose times. Not half at each dose time. Check with your vet.
And bottles from the vet should still have concentration amounts, call
them to find out.

Also, when getting a recently diagnosed ferret on meds to control the
insulinoma they need their bg rechecked to be sure it is under control.
With the symptoms you're noticing you need to check the dose
immediately with your vet, adjust it, and recheck the bg a week after
that. Sooner if you are already giving the correct dose.

After time even ferrets who are regulated well on pred and/or diaoxide
will need periodic rechecks as their insulinmoa progresses. At least
every 6 months or when you notice signs.
