He will start a file to design that too.

"There should be places where the - not sunlight but light - streams in."

"Like a window, or like a ceiling window in particular, or like a window with a light outside it?"

"All of those might be nice.  But it shouldn't be light all the time."

"Sure. You can have curtains, if nothing else." Tinker twiddle fiddle.

"What are those?"

"Fabric that goes in front of windows to keep out light and prevent people from seeing into your home."

"Fabric is the thing Twoleg pelts are made of?  Why do you do that?  Should cats too?"

"There is no particular reason for cats to wear them. Twolegs often find it more comfortable and attractive in addition to preferring to not look at some parts of each other's bodies most of the time."

"How could I tell if it's more or less comfortable if I've never tried it?  I don't know about 'attractive' per se but the one Mistoffelees wears looks kinda nice.  And I think Twolegs are nicer to her because of it."

"Do you prefer not to look at the parts of our bodies that her thing covers?" another cat deduces.

"I guess it might help if you were cold but I think having fur probably obviates all the other comfort-related features. And no, actually, the main thing is anuses and genitals which seem hard to cover comfortably on a cat. Twolegs are probably nicer to her because it means a Twoleg is taking care of her, I don't think it's necessarily better than a collar at that."

"I've seen them make different noises at her, though.  And point at her with their paws."

"Yes, it's more remarkable than a collar."

"I want one."

"A vest? Sure - does hers have anything to let her take it off and on herself, do you know?"

"I dunno."

"Then I will have to ask her and her human about it." He can text Ellie, at least.

I usually help her.

"Her human says usually she helps. Are you sure you want one if you can't manage yourself?"

"Jerrie and Teaser had collars they could do themselves; can't you just do that but bigger or something?"

"I can try but I do not know if I will succeed."

"Okay."

Cam fiddles with his computer in yet another file. "Color, style, fabric thickness?" he asks, while he scrolls through fastener possibilities.

"Uh, maybe that color," she bats a paw in the direction of the nearest wall, a pine green.  "I don't know, you're the one who wears them normally.  Maybe something with - I don't know the word.  When they have a lot in a little space and it fluffs out."
