Phil, your best best is to call Animal Foundation and let them know. They will trap the kitties, fix them, and then release them where they were found since they are feral cats.
Need to contact C5 and trap those cats. Have them spayed and neutered so they stop reproducing. They might be able to help you with that. They do fix many of C5 cats that they trap and release.
Sadly No..hcws is a fixing facility only..
