As another photographer, remember exotic places are always tempting and can be very fun, but travel doesn't make good photos. You make good photos, and you can do it close to home.
So if you want to take beautiful photos of tigers you do have to find tigers, but you also have to be able to take beautiful photos. The tiger won't solve that for you.
(Now, if you're already a great photographer, good enough to sell your works, then you have the skills, so by all means devote yourself to pursuing subjects)
