Trap-Neuter-Return programs combined with responsible management are the most viable, long-term approach available at this time to reduce feral cat populations. By utilizing the Mobile Unit The Clydey Foundation can help to prevent the growth of feral colonies with the help of the community.  Responsible management of existing feral cat colonies should include: humane trapping, sterilization, rabies vaccination, and treatment for illness or injury; removal of kittens and friendly adults for possible placement in homes; euthanasia of animals whose suffering cannot be alleviated; ear-tipping and returning ferals to the same location where they were trapped provided they would not face imminent risks; and providing lifelong care consisting of adequate food, water, and shelter as well as regular monitoring of the colony for sickness, injury, and the arrival of new animals. The goal of any feral cat management program should be to maximize quality of life for the cats and to eliminate the existing colony over time through attrition.
