lions vs tigers

[Catherine]

I think you are right that there are more lions in captivity and more lions tamed. Tigers are very solitary so they can't be kept in a group. In the same amount of space you can keep one tiger or a set of lions. Lions seem to breed well in captivity. It is posible that tigers are more intesely feral.
I don't know if anyone has seriously studied this.
I have never heard of anyone keeping a pet Cougar. I don't think they tame very well either.
