Shivam male sub adult cub of Bhanuskhindi Tigress

Whilst he came back after a long walk he sat down in front of my gypsy. Suddenly he heard some noise in bushes, and he started watching it continuously. Then he went for the kill, it was a civet cat. But what happened I could not understand after catching it he did not kill it nor ate it. All of a sudden, he let it go. He was sniffing the entire area and then he moved on to join her sister and other brother.
