They’re already showing differences in purrrsonalities. Jax here is the most eager for a lap and full head massage. Jumbo is best at returning to the food dish and filling up again (I chose right in the name). Jet cries when he uses the litter box–apparently not because it hurts but because he’d rather be doing something else, such as lying down pulling himself around by grabbing things with his front paws. And I think it’s July who had been hissing when I’d first come in, not seeming upset nor scared, and purring shortly after.
I’ve been giving them time to explore the room, and they’ve been very good about using the litter box, and returning to their area, or the crate, to nap afterwards.
