It's been mentioned by a couple, but I think gets lost in the talk about processing.
This is a prime example of where photographers should be using their eyes to assess the image in the viewfinder. I understand the will to get the shot, but the dappled light is going to give you an image that'll need PP work to make 'right'.
When it's 'right' will the image justify the work? Would the OP have been better waiting for the tiger to move? If the tiger moves forward into the light, there's less chance of the fence in the background. If it moves back into the shade, a slightly different angle might give a better finished image.
But it's just easier to pretend it can be 'fixed in post', rather than asking photographers to consider the photography, we're giving advice to improve what can only be described as a snap, when we could be giving advice to elevate it to a photograph. </rant>
