Rebecca says, "Hey, efurrykittee -- luk up!"

The night sky is shimmering. There are faint traces of violet, indigo, blue,
green, yellow, orange, and red. The colors come together and become more
vibrant and then, there it is: the Rainbow Bridge! When the kitties look
closely, it seems they can see old friends along its length: other kitties,
hoomins, doggies, and others that they knew and loved in the past. The loved
ones at the bridge are looking back and waving to those still on Earth.

Who do you see?
