Sasuke told him to agree to give him a print of his paw, however Nekomata used his genjutsu on Sasuke. He was able to cancel it with his Sharingan. After that, Nekomata and Sasuke started to fight with Taijutsu, just when Nekomata was about to crush Sasuke with his paw, Sasuke is saved by Naruto and Sakura who managed to find Sasuke.
