After Denka and the two Ninja Cats delivered Sasuke and Might Guy, they still had to return to the place where they had found them and continue their patrol.
Duty called, so they could only leave reluctantly, looking back at Sasuke every few steps.
The Ninja Cats had undergone enlightenment and could still restrain themselves somewhat, but ordinary kittens...
