Standing still, the knight gave no signs of fear or unease about the creature. That'd only provoke it, and truth be told, she didn't feel worried. If this creature attacked her, she'd defend herself as was appropriate.. even if it was someone's pet. It'd be unfortunate if she had to put it down, but hopefully the owner would understand.

However, Saber did put out her hand in the very universal pose that someone used when wanting to reach out to offer a hand to pet an animal. Of course, her hand was way below the creature's head, and not above as would have been normal, but..

It was worth a try. If anything, she could attempt to calm down this creature that was frolicking so.
