Kellen learned that the 85-year-old woman's name was Lida, and that she was from Uzbekistan. She struggled a little to speak in English, but soon began to talk about a beloved pet of her own whom she had lost.
"She told me about her cat that died at 12, how beautiful he had been and how she missed him," Kellen said.
What happened next was something truly beautiful. Kellen watched in awe as Lida and Darwin joyfully played and nuzzled together like old friends — each seeming, in that moment, to transform into their younger selves again.
"I was trying to choke back a lump in my throat the entire time she was with us," said Kellen. "Interacting with Darwin, she really shone."
