Random Riddle: Liger

Once, there was a lovesick tiger who fell in love with a lovely lioness. However, her pride rejected him, and they were not allowed to be together because he was different.

Heart sickness and grief caused the lovely lioness to lose all of her fur. Even though it was a sad sight, the tiger was overjoyed! Now he would shave off all of his fur. Then he could pretend to be a large lion and be with his beloved.

Unfortunately, they did not get to live happily ever after! His plan failed. Even with his fur gone, everyone could tell he was a tiger.

Ignoring any obvious size differences, how did the pride know that he was obviously still a tiger?
