Can you give this to tortoises

8th Sep 2015

My tortoise won't eat food with calcium powder on or cuttlefish so I wanted to know if this was ok for tortoises?

Hi Clare,

It should be ok for your tortoise. Zolcal D is a liquid veterinary medicinal formulation of calcium and vitamin D3 which can be given via drinking water. Over supplementation can occur so care must be taken not to exceed daily allowance.
