Cross breeding is wrong end of story, I don't hate the crossed animals but it's not right what humans are trying to do in this freaking earth, it's dumb & people still are not smart enough to stop this madness.

It's not like tigers and lions are over populated breeds like dogs.
No there not over populated there CROSS breed, that's the point.
Second issue circuses. They are not mean and inherently cruel. You're pet is not abused by being taught tricks or doing them in front of people, agility shows, dog shows. I've even seen llama agility! In fact if you don't train your dog and interact with it it's considered neglect. Really it's the same for exotics. They get enrichment by learning and doing tricks. Even zoo animals are usually taught to do some simple things like target. You may not call it a trick but there's no real difference. The animal is being taught to do something on command.
Most circuses use chains and electric shocks to control animals,

I went to a circuse in Toronto & the stupid man was using an electric poll at the poor elephants just so he could get them to do what he wanted, no matter how tame a lion is in a circuse it's still not right because these animals feel stress with all the flashing lights & screaming of kids .. I mean people should leave them in the wild .. I don't even like Zoo's anymore because I feel the animals should be free and not breed in captivaty.

These animals are dangerouse and if they show there natural anger to a human they will be killed for doing what only comes natural & I know its NOT fair, you have a exotic pet but it's not in stress & your not having flashing lights or strange people looking at it all day like in zoo's or circuses so there is a difference.
