I just received my order of cactus pad and I was wondering what is the best way to prepare it. I guess my biggest concern is the little thorns that are still on it. Do I peel it first or just rinse and give it to them? I can only imagine that it would be painful to bite into one of those things. Also, I'm keeping them in a plastic bag with the rest of their greens in the crisper in the fridge. Is that ok?
