In every state in which I am familiar there is strict liability, with no exceptions, for wild animals such as tigers. It does not matter in most states what you do to protect the public, if you have a wild animal such as a tiger, you are going to be liable whenever the tiger hurts someone. The thinking is that you are assuming a great responsibility by harboring a wild animal; therefore, whenever it hurts someone, you are liable even if you were exceptionally careful.
That should answer your question.
I hope that I have helped, answered all of your questions, and that I have provided you with useful information. Please contact me if I have not answered all of your questions. If my answer is satisfactory please accept it. I really appreciate positive feedback.
In the future, you can specifically request that I work with you on your legal question. If you have specifically requested that I answer this question, thank you.
Please be aware that my answer is not legal advice, it is merely information. You and I have not entered into an attorney/client relationship. The only way that I am legally responsible for your legal rights is if you have signed a written retainer agreement with my law firm.
