Just curious about feeding my red foot cactus pad and where to get it. I live on Long Island and I have read about cactus pad for tortoises. I guess my question is what exactly is it called? Is it spineless? I have seen some in produce stores but still seem to have spines on them. Is there a place on line that I could order the correct ones? How long do they keep? My girl is a little over a year old. Thanks for any information.
