Thankyou for the advice. After posting (in a bit of a 'panic') I looked at the posts and also found your advice in the thread 'hypervitaminosis'.

So I'll use miner-all o (calcium , but no D3) at every feeding, Miner-all 1 (calcium with D3) every couple of weeks, and I'll gut load the crickets with a healthy diet Vit-all as a supplement, and hope for the best. I've read a bit about the syptoms of hyper/hypo vitaminosis and hope I will recognise these conditions if they occur.

Incidentally, the makers of miner-all 1 (containing D3) suggest that it is given at every feeding (juveniles)-this seems somewhat extreme! Is the stated amount per kilo of product (4,400.00I.U)particularly low? I ask because this product was developed specifically for chameleons, so presumably the makers have found no evidence of overdosage at this level?

Thanks again for the advice
