TNR (Trap Neuter Return) is the humane and effective approach for stray and feral cats. Now in practice for decades in the US after being proven in Europe, scientific studies show that TNR improves the lives of feral cats, improves their relationships with people who live near them, and decreases the size of colonies over time.
Colonies that are involved in TNR diminish in size over time. TNR quickly stabilizes feral cat populations by instantly ending reproduction and by removing socialized cats from the colony.
The Hayward Shelter is starting a TNR program. For a small donation ($50-75) you can bring a feral cat (these cats are not friendly or social) in a trap to the shelter on a designated day to participate in the program. You may learn more by calling 510-293-7200.
