The other trick the cat tried was seeing if she could get back in her travel box and if that would summon me.
My sister reported the cat not eating and puking what she did eat, but at least over her first night back home her diet is back to normal so I think she was just trying a hunger strike in hopes that I would get back from vacation early. Will still keep an eye on that to see if there's something more serious going on, but her other behaviors are also back to normal so far.
Hit a diner for brunch, a couple coffee places (Mom has been dissatisfied with the coffee all trip because she's used to coffees I roast, but I'm okay with competently executed coffees even if they're not how I would choose to roast them), and found a video game arcade with some good stuff to kill time at. I left a couple high scores, but I'm pretty sure those get reset overnight.
