I believe owning different exotic and wild animals should be banned completely, all over the world. Its terrible to take them away from their home and, its not good for the owner and the wild animals to live together. But, yeah, as you said, Hellow;

I think that it should be okay to keep "exotic" pets as much as you want, so long as you have proper provisions to keep them for the maximum extent of their lifetime and provide food and healthcare for them.
Only then should a person be allowed to keep an "exotic" pet. But, it shouldn't be the ferocious, attacking type...
