"Yes but I can wait."

And they generally headbump and rub on him.  One of the back-of-couchers hops down directly on his stomach and starts making biscuits.

Scritches for all the kitties. "It's nice to meet you all, I'm Cam."

"Yes, we knew that!"

"Rude.  I'm Charlie, or Char-char, or Leeby-deebity, or Leebicus, or Charlicus, or Kitty, or Kitty Baby, or Stinky Baby, or Sweet Baby Idiot, or -"

"I'm Luna, or Lulu, or -"

"Can we please limit everyone to one name.  I'm Haydrox."

"I wasn't being rude, I just meant that we were all waiting for you and heard things about you.  Leo."

Pet pet. "Are we time-dilated?"

"Yes!"

"Oh good." Then he will have lots of subjective time to pet all the kitties during his catnap.

One of them, who introduces herself as Senator Gracie, starts crying humanlike tears a ways in.  "It's been so long," she sniffs in explanation.

Petpet. "How long?"

"I don't know.  Longer than I was alive."

"You died a few years after I did, and I've been dead much longer than I was alive, maybe twice as long, and I died old . . ."  He's tearing up as well.

"Were you all talkers your whole lives?"

There are six 'yes'es and three 'no's.

"See, I'm trying to figure out about how many talking cats there are right now. Some of them are in shelters and will probably want to leave and it's complicated to get them out, but how complicated changes with the number." Pet pet.

"I've met every dead cat but big numbers only happened two days ago so I haven't counted them."

"Wow, every single one? What a social lunamoth you are." Scritch.

"Well, a lot of the Clan cats didn't like me but they hang out in groups so you can meet lots of them at once.  And I didn't want to miss out on anyone who would be a good friend just because I hadn't met them, and then when cats die of course they usually need a whole new friend group and that's scary so I help them out if they need it."

"That makes sense." Petpetpetpet. "Can you give me an estimate now that you have big numbers?"

"Hmmmmmmmmm."  (Prrrrrrrrrrrrrrrrrrrrrr.)  "Hundreds?"

"Welp, depending on what fraction of them are in shelters right now that's going to be a whole undertaking. Do you have a loose idea of what fraction of them have been in shelters at any point in their lives?"

(Rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr.)  "No."
