We did a road trip from Portland to Tahoe, spent a week with friends in a cabin, picked up the daughter from her summer camp, drove to Yosemite for a couple nights, then Monterey, just got home yesterday.
In a campground in Hardin Flats, around Groveland CA (on Hwy 120, near Yosemite), we met a little cat. The camp folks said it had been abandoned there a few months previously. Friendly, hungry, skinny. We decided it wouldn't survive the winter, so we took the cat with us, to drop it at a shelter on the way to Monterey. So now the cat - identified by a vet in Monterey as a 10 month old female - is at our home in Portland, getting introduced to the home and, soon, the existing cat.
Hoping the introduction goes well. Worst case, the young cat will go to our local humane society shelter, which is an excellent one and a no-kill facility. Wish us luck!
