Escuse my ignorance I don't know much about plants
Do these plants eat bugs? If so isn't that cruel? Why would I care about feeding plant? If that happens in nature that's fine but cultivating it doesn't seem to me fun. By the way I don't like keeping piranhas either.
By the way long time ago I lived with a nonmuslim roomate who had iguana and used to feed him with alive rats. That was cruel and disgusting!
