How to rent wild animals in Las vegas?

I am a student photographer in Las Vegas. I really keep having a ton of ideas for photoshoots with lions or tigers in the shots. But I can't find ANY place to rent big cats from. I know they're dangerous, I would not want to shoot without a trainer present, but I want to make this idea happen. Does anyone know where there are places that will let me shoot with their big cats? MGM and Mirage already said no (obviously).
