The 6-week-old striped kitten abandoned in a drop library box in Cheltenham died Wednesday night at the Montgomery County SPCA, the organization's director said Thursday.

"I am very down as well as our entire staff. We did our very best. We were hopeful for a happy ending, but the cards were stacked against him," Carmen Ronio said.

The 15-ounce cat, which the shelter staff had named Hemingway, had come to the Conshohocken shelter suffering from severe dehydration, diarrhea, and a respiratory infection. Ronio had said early on that he wasn't sure the cat would survive, but it rallied briefly Wednesday morning from treatment including fluids and antibiotics.

The cat was shoved July 22 into the library drop box at the La Mott Community Center and discovered by a maintenance worker early Friday.
