Hehe, definitely not angry! I agree with what you wrote. Thank you.I'm not staunchly on either side, or an expert but I figured I'd add:
Coconut oil has antibacterial and antifungal properties. If it isn't caked on, it could theoretically provide a slight advantage in avoiding fungal or bacterial infection.
Iirc, Tortoises do not absorb uvb through the shell. Only the skin. Application of coconut oil to the shell should not hinder uvb absorption. Occasional application to the skin should not have much impact either, given the uvb exposure needs of tortoises amount to about 3/4 hours of sunshine a week.
I guess what I'm trying to say is I don't know if there's any benefit, however I can't really imagine there is any real concerns either.
Please don't get angry at me! Just another voice chiming in!
