I bought some spineless prickly pear cactus online to replant for my tortoises to eventually eat and after planting when washing my hands I realized I had 2 or 3 tinyyyy little thorns in me. Are these on spineless prickly pear cactus still? I feel like that would be terrible in my tortoises throat. The cactus came without the big spikes like other cactus have, but apparently these little things are somewhere on it, at least a few... is that normal or did I get the wrong kind of cactus?
