Sure, he can take off the coat and shake his wings out.

Everyone would also like to sniff them, please.

Cam puts up with this.

Rumpleteazer gives everyone a rundown of her conversation with Cam while they do.

"Hmm."

"You smell kinda weird."

"I'm sorry to hear that."

"It's not awful, just . . . weird."  Felicity is getting some sniffs as well.  "Her too, but different."

"It would be odd if we smelled identical, I guess."

"But your weirdnesses aren't at all the same."

"...okay. I don't really have any light to shed on this."

"How many cats can you take with you today?"

"All of you if you all want to come!"

"How will we get all this food, if not by hunting?  Are you going to keep us all inside somewhere?"

"I can make food out of nothing." He materializes some sashimi and hands it to the first cat who definitely wants it. "And you don't have to live in a building, though the city is in a pocket in the side of the world, so there's a ceiling over the whole thing."

"Mungojerrie said you could. But how will we get it?  Will you be all of our family?"  'Family' in this instance isn't a word that cats use for each other; it's specifically for humans.

"I can make food that will last a long time, and I can leave it somewhere convenient for you and you can go get it from there whenever you want. I'm probably not going to be around enough to be family for everybody in other capacities."

"Oh, good.  I prefer that."

"How convenient. If any of you do want family there are people around but it's currently pretty hard for you to communicate with them, that's a work in progress."

"But that's not any different from how it is already.  Unless knowing we could be communicating mucks things up."

"I don't think it will be worse but it will mean humans might be awkward about, say, petting you, since the etiquette will be unclear at first."

"What does it have to do with that?"

"...it's kind of complicated and I don't even know if everybody else will have the same intuitions I do about it. Suffice it to say that there's a few cats working on making it so anybody will be able to talk to you and vice-versa."

"Can I help too?"

"I don't see why not."
