The West Philly-based feline rescue group City Kitties announced this morning that it will stop attempting to rescue cats that may still be inside the Windermere Court building because it is becoming more structurally unstable.

The group wrote on its Facebook page this morning:

Our trapping efforts inside the Windermere are over. The building is deteriorating, & we had to weigh the safety of the humans involved against the possibility of finding more cats. None of the 5 traps had any food eaten out of them or paw prints inside. We feel confident that no cats remain inside. Doors & some windows are open; cats DO have an opportunity to escape.

City Kitties has a page that lists the cats, including photos, that are still missing at the Windermere.
