Is it a good idea to put clacium powder in a spray bottle with water and spray so he gets in clcium when licking off leaves.also is it alrite to put some in a water bowl where a water dragon swims and drinks?just a idea
I don't see why not. It's very difficult to "overdose" a reptile on calcium intake in captivity, so I say, offer it anyway he takes it: on food, in water, misted on, etc.
If you are feeding a PROPER diet and are lightly dusting his food then that should be more than enough. Also dont forget that a FULL SPECTRUM BULB IS ESSENTIAL. DONT cheap out here.
If you spray the cage with calcium enhanced water you are going to leave a residue all over the cage. Its not going to be very attractive.
