I wanted to add that since Vit D plays a role in the transport of calcium, it is imperative that it be added to the diet and maximum UV provided during the recovery phase, even before the outdoor enclosure is finished. All the calcium in the world can be added, but without Vit D, it can't be utilized properly.

Agreeing with everyone else, I don't think severity of hypocalcemia can be measured by visually looking at the animal. However, the tremors should have resolved by now.
