We kept the names they came home with. One is black and is named Pepper. The other is a striped tabby with white chest and paws and is name Piper.
I would say they are now completely adjusted. And mischevious! They are always tearing around the house at night with their claws catching on the carpet. They are pretty comfortable around the girls, except for Avery. We leave them out at night now, and they like to sleep at the foot of our's and Eden's beds.
Piper is affectionate but a bit nervous. He has figured out how to wiggle between all the storage containers under our bed to an open space at the middle near the headboard. He loves to follow us into the bathroom for some reason.
Pepper is more independent. He's not one to rub up against you or sit still for petting. But he also doesn't run off as much as Piper. Pepper seems to take a certain satisfaction in sneaking up on and frightening Piper. And Piper always reacts.
One of their favorite activities is to sit at an open window or the sliding glass door (behind screens of course) and watch "bird and squirrel TV". We have a big stand of bamboo near our apartment where dozens of birds roost every night. It's usually pretty loud out there around sunset. I wish I could understand what they were thinking as they watch all the birds winging in to roost.
