This reminds me of a personal experience; not only is the story similar, but in both cases, the kittens are white.
Several years ago, a friend of mine, manager of a municipal cat shelter in Appalachia, was given two tiny kittens who'd been found by the side of a ruarl road. Both, of course, were undernourished and extremely frail. In spite of the best efforts of my friend Cathy, the little boy passed on, but Cathy took the little girl under her personal wing. Because I sponsored the little girl, Cathy let me name her, and I called her Frosty, since she's pure white. I forgotten exactly how much Frosty weighed, but it wasn't more than a 2 or 3 ounces; she easily fit into the palm of Cathy's hand. Cathy, along with her volunteer, Cynthia, would feed Frosty every 2 hours while they were at the shelter. When it was time to go home, Frosty went with Cathy, who continued the feedings throughout the night. When Cathy had to travel 2 hours to the nearest hospital for tests, Frosty went, too, Cathy's husband making certain that Frosty got her regular feedings. With all this, Cathy *still* had the shelter and all its cats to manage! Frosty thrived and turned into a long-haired beauty. Cynthia couldn't resist, and adopted Frosty, whom she renamed Priscilla. I'm told that Priscilla is queen of the house and has adopted Cynthia's husband as her own human.

If anyone ever feels as if you'd like to make a donation in memory of a departed furchild, just pm me, and I'll give you the name and addresss of this wonderful shelter (Cathy is now director of the entire shelter, cats and dogs) that remains no-kill in spite of the attitude of some of the local officials.
