I was at the pet store the other day and saw a product that I'd never noticed before. I didn't inspect the item much, I only glanced at it, but from what I saw, it looked like it was a calcium spray for reptiles. Right now, I use a calcium/vitamin D3 powder, and it's so messy and it sticks to my fingers. I hate dealing with it. I was wondering if this spray would be a suitable alternative. I wish I'd checked the bottle more thoroughly to see if vitamin D3 is included... Anyway, does anyone use this spray on their beardies' food, and is it effective? Thanks.
