TNR - overcoming objections

TNR involves several aspects to be successful. First we humanely trap each cat and transport it to a vet for testing for disease, vaccinations to keep it healthy, and it is spayed or neutered to prevent further populations of cats from being born. (After a cat is surgically altered, it will stop many, if not all, of the undesirable behaviours, such as spraying urine to mark territory, howling and fighting during mating, and it will improve the cat's quality of life.)
TNR Part 1: If the cat is feral or wild, we would opt to return it to the original location - relocation is rarely an option, as it requires weeks of containment in the new area to ensure the cats doesn't just run away. A newcomer cat is not always welcome in an existing or new colony and would have to fight for food and hierarchy within that colony.
TNR Part 2: If the cat is tame or we find a kitten, obviously we don't want to return it to a hard life on the streets, so we put it into an adoption program.
TNR Part 3: If the cat tests positive for either Feline Leukemia or Feline AIDS (FIV) then we would opt for humane euthanasia. This prevents suffering of the individual sick animal and also serves to protect the countless number of other cats who could be infected from one sick feline.

TNR = Trap, Neuter, Return: It is all part of having a healthy, stable, sterile colony of cats returned to keep the colony from growing. Google information on the vacuum effect for cat colonies that are simply removed, you will see that it is only a band-aid to a much larger problem. Removing all the cats simply leaves space for more cats to move into the territory and start reproducing. They cycle continues. Once a whole colony has been TNR'ed, if a new cat is abandoned or shows up at a colony that has already been fully fixed, then we can catch the newcomer right away and get it fixed to prevent more kittens.
I got 2 females from the Cove spayed last week, and both were pregnant... Do you think I should have left those dozen kittens to be born outside and suffer with the rest? NO - we must spay and neuter all the cats there ASAP if we don't want dozens of kittens being born this season. Of those born, less than half will survive to 6 weeks, succumbing to cold, starvation, infection and parasites, or being eaten alive by larger prey. So let's do TNR to help the whole problem. Some objections are easy to overcome, others need a little research into a solution, but I believe that we can do it!

Once returned, the cats will have 3 things to improve conditions:

1. Shelter
2. Feeding station
3. Litter boxes
