Stray and/or feral cats are humanely trapped and taken to the vet to be spayed/neutered. And then released back into neighborhood / area from which they were trapped and cared for by kind citizens in that area.
TNR is promoted by the ASPCA as a humane and more effective alternative to euthanasia for managing and reducing feral/stray cat populations.
Over time, populations decrease because no new litters of unwanted kittens are being born.
PAWS provides the use of traps and financial assistance if needed.
Keep innocent cats and kittens out of shelters!
