Ive just got to panther chameleons and im gonna do the same as my veilds plain calcium every feeding and a d3 calcium once or twice a month and vitamin supplement once a month but if anyone thinks this should be different im open to suggestion
It depends. There is no single fixed schedule that fits all situations.
What brand of supplements are you planning to use?
What feeders/prey do you plan to offer?
Does your panther live outside or inside? what brand of UVB lighting are you using (if any)?
etc
