I have a bioactive enclosure and like to add new plants for my dragon all the time. I'm having some issues finding if the Thanksgiving cactus is safe or not for him if he ingested it. I have found that it seems to be safe for dogs and cats, but I can't find information with it and dragons. When I try searching, I just see things that say cactus is safe for them. Nothing specific about this type of cactus though.
