Also there are Hispanic ladies online that have ideas for removing the spines. It looks pretty easy and it's a regular part of their diet. I won't feed my tortoise the spines either even though I know you can. He doesn't like them so it doesn't really matter anyway.?I have been removing the thorns, each one individually with a parry knife while I submerge the pad in cold water ( Like removing the eyes of a raw potato). I know it possible to feed your tortoise some pads with thorns, but I will continue to make sure I get the thorns off before feeding. Like I said before, Sammy is spoiled and just after having his for just over 3 years now, he has me trained.
