"Hello?"

"Hello, sorry to bother you, but your cat found me and wanted me to carry her home."

"Oh . . kay.  Thanks."  She holds out her arms for Princess.

He hands her over. "Also she had something she wanted to say to Jackie, are you Jackie?"

". . . Yes?"

"- do you want me to demonstrate that I can talk to cats before I pass it on?"

"I mean I can also talk to cats, here, watch.  Hey Princess, who's a good kitty?"

"It's me!" she squeaks.

"Yes, yes, and I can call spirits from the vasty deep, but I mean to say that also I can understand what she says and we can have elaborate conversations."

"Ah-huh."

"Like I said, would you like me to prove that."

"Why not."

"Suppose you give me a set of complicated instructions that, unlike inquiries as to the goodness of kitties, you would not expect Princess to be able to follow, and I relay them?"

"Well.

She normally wouldn't ever scratch me.  So that, I guess."

"...uh, are you sure? I was imagining something more along the lines of, like, bringing you a specific object or something."

"Yeah."

Cam sighs, and meows: "Princess, for unclear reasons Jackie has chosen as her means of proof that she would like you to scratch her."

Jackie snorts.  "At least you're committed to the bit."

Princess's eyes are enormous.  "But I would never!"

"Yeah, that's why she picked it, specifically because you would never. I guess you could extend your claws and approach her hand with them and look up at her and see if she nods?"

"Okay . . ."  Claws out, paw approach?

Actually Jackie is trying not to display any body language at all.  She's not even looking at Princess.

She sheaths her claws and makes a scratching motion without them??  When that provokes no response she extends them a little and moves her paw very gently, definitely not enough to break skin and with barely even enough pressure to leave little white lines.

"Huh."

"She said 'but I would never' if you're curious."
