Aids farmers and others who willingly house unowned cats in barns and other outbuildings, by trapping, vaccinating, spaying or neutering, and treating (if necessary), and then returning cat(s) back to their colony (group) in the wild or barn. Also offers a Working Cat program for cats who aren’t socialized enough or have other limitations for home adoption, to be placed for free in commercial or outbuilding environments where rodents are a problem. These cats are spayed/neutered and have at least rabies and distemper vaccinations. This non-traditional approach allows these cats to receive shelter, access to food and water, and the care they need while offering the service of expert rodent control to their adopters.
