Open your supplement shelf. If you have only one bottle, order calcium-without-D3 today. The everyday dust is the load-bearing one.
Why calcium without D3 carries the daily load.
Five days a week we dust with calcium-only. The D3 version comes Wednesday. The multivitamin comes Friday. Here is why the rotation is staggered.

Calcium is needed every meal. D3 is not. A chameleon under proper UVB makes its own D3 in the skin during basking. Supplementing daily D3 on top of working UVB is a path to hypervitaminosis D in the long term, particularly in animals that bask consistently.
We use calcium-without-D3 five days a week as the default dust. Mid-week we add calcium-with-D3 once for animals whose UVB exposure may be inconsistent. Friday gets a reptile multivitamin once weekly — not stacked with the D3.
Vitamin A in the multivitamin matters. Preformed vitamin A (retinyl palmitate) once a week prevents the early signs of hypovitaminosis A we wrote about earlier in the cycle. Beta-carotene supplementation alone is not sufficient for chameleons.

A 72-hour gutload window for dubia roaches.
Dubia gutloads peak somewhere between 48 and 72 hours after the colony moves onto a fresh diet. Here's the schedule we run.
Feeder rotation: crickets, roaches, BSF larvae.
A single-feeder diet is a nutritional gradient that flattens. Three rotated feeders give you slope and recoverability when one source goes offline.
Fasting protocols for adult panthers.
Adults benefit from a structured fast. Two days a week without feeders, hydration unchanged. Resets the gut and prevents the slow obesity creep most adults trend toward.
