My juvenile blue iguana Loki has been on emeraid (a calcium phosphorous supplement prescribed by his vet) for a good two to three months now and will still not eat his salad. He has no problem however eating his emeraid with no forcing whatsoever. The last few days I've been shoving small pieces of collards in his mouth which he at least eats and does not spit out. What should I do to get him to just eat his salad instead of the medicine? How should I wean him off the emeraid?
