My iguana used to not eat repcal and I had to hide the pellets in its foods. If you remember, I made sandwhiches out of leaves with rep-cal pellets mashed in between. I would feed the rep-cal 3 days a week or so for some extra protein.

Now, my ig actually REFUSES anything that doesn't have rep-cal pellets on it, clearly visible. It would not eat anything that has no rep-cal pellets on it anymore. I've given it plain leaves for days and it would not eat. Today I gave in and put some rep-cal and its in there chowing down right now.

I know that you can gradually "wean" them off of the rep-cal by reducing the amount gradually. However, I don't want to get him off of them, just not everyday. This is because the pellets DO have D3 in them, and despite the fact that I hear (but have seen no proof nor numbers etc. just hearsay) that the amount is negligible (how do you even know?), that there can still be issues with feeding it on a daily basis.

If I wean him off of it, it means I don't feed the pellets at all anymore. If wean him off, but feed a little on certain days, then he's eating them and will still be picky like now.

I have no idea what to do about this one.

I'm not sure exactly how to help you with this one either. But I'd like to try. What if you took the amount of pellets that you wanted to feed him over a week in the 3 day span, and divide it up so you'd give him a very small amount everyday.

Or perhaps (I am sort of "thinking out loud" here), is there a particular food your iguana likes, other than these pellets? Something your iguana can not refuse perhaps? What if you added that something to your iguana's food on the 4 days you don't feed the pellets?

I hope that I helped...even if a little. I just saw that no one responded to you, I thought I'd try.

Good luck!
