Unnatural Behaviour
Tigers living in captivity never get a chance to do what they should be doing which includes chasing animals, hunting their meals, finding the mate, living in freedom and much more. Hence, they might lose their natural instincts, get scared and don’t even behave like tigers.
Something similar happened when a white tigress gave birth, sadly, she had no motherly instincts. And the cubs hardly survive in such situations. A glimpse into the lives of these poor babies will melt your heart.
