Low-cost Neutering for a stray-female cat living in my backyard

Washington DC

Description

Hello: In my backyard, a cute Stray-female cat has been living for the past years. In general, she is a good cat, however she produces 3-4 litters every year. Is there any 'low-cost' neutering service or a volunteer-service to get her neutered? Please e-mail me soon. Thanks,
