Morning View - Feral Cats

Riding my bike around Roosevelt Island, I ran across a few volunteers tending to a large colony of feral cats. The cat ladies out there recently formed a group called Island Cats, which operates a TNR (trap/neuter/return) program. They told me that the feral colonies on the island number about 100 cats, but many die during the winter. I don't recall having seen any feral cats in Manhattan.
