A friend sent me the link to this video with this message:
"We can learn a lot from our furry friends. This is a video of a homeless guy in Santa Barbara and his pets. You can see these guys every week working State St. for donations.The animals as you can see are pretty well fed and I can attest to how mellow they are. They are, a family.The man who owns them rigged a harness up for his cat so she wouldn't have to walk so much (like the dog and himself). At some juncture the rat came along and since no one wanted to eat anyone else, the rat started riding with the cat and often, on the cat! The Mayor of Santa Barbara filmed this clip and sent it out as a Christmas card."
Their names are Booger, Kitty, and Mousey, and their human companion is Gregory Pike.
