It's the last hope for cats nobody else wants. Cats like Overton, who has feline leukemia virus, a disease that could kill him at just 10 months old. "I would say without proper nutrition and vet care the prognosis wouldn't be great," says Crystal Chiechi, operations manager at Purrfect Pals. Overton and thousands of other cats have been saved from euthanasia by workers at Purrfect Pals in Arlington since the operation began in 1988.
