hi roly,
no need for an apology. i just wanted to clarify what i was trying to say in my hastily typed contribution. this is an important and volatile issue, and i should have taken proper care in explaining my points. (dewlaps retracted)
i study sex behavior in lizards (and tortoises). in experiments where we need to manipulate steroid levels, i perform gonadectomies on the lizards. i've worked with Sceloporus, Anolis, and Cnemidophorus, and have found a higher survival rate using ice emersion than several different injectables. though we don't know for sure, the complete lack of spinal reflex suggests to us that pain is not an issue during the procedure.
