Nestor is our Chin. We've had him since our 2nd anniversary (4/2/2013), and he's a little over a year old. We thought he could use a little more room to run around, so we just bought a new cage twice the size. He seemed to be uncomfortable with wire underfoot, so we cut some raw pine ledges for him to clown around on, and then gave him a raisin to look for. It took him a couple of minutes, but he worked it out and got the treat!
