When we moved from NH to Mass 10 years ago, they literally hid in their litter boxes nearly all day, only coming out briefly to eat, and that went on for almost 2 WEEKS! It was like there was no cats in the house. Here, Floppy came right out of the carrier immediately, and when he saw all the stuff from the old house, he understood. Robo and Ivan stayed in their carrier about 2 hours more. I'm blown away how fast they adjusted after the the first move I described!
Floppy, Robocat, and Ivan are back in their native NH, after 10 years in Massachusetts. There's no screen porch or cat enclosure here -- yet -- but stay tuned, there's a huge deck attached and a big yard, and the Purrfect Fence is already in the new garage. In the meantime, they have a bigger house with lots more sunlight. Three days here, and they are liking it already!
