These colonies can be managed through a nonlethal method called Trap - Neuter - Return (TNR), in which cats are humanely (and painlessly) trapped, spayed or neutered, and returned to their colony site where volunteer caretakers provide them with food, water and shelter for the duration of their lives.

TNRM begins and ends with volunteer caretakers, the dedicated individuals who take the first action to help hungry cats living outdoors. (thecatconnection.org)
The cats are humanely managed by volunteer caretakers for the entirety of their lives with ongoing support from Tree House as mandated by Cook County's «Managed Care of Feral Cats Ordinance». (treehouseanimals.org)
