Trap, Neuter and Return (TNR) is widely recognized as the most humane and effective strategy for reducing feral cat populations.  TNR involves humanely trapping feral cats living in cities, towns and rural areas and transporting them to a  veterinary clinic where they are spayed or neutered. They may also receive a health check, vaccinations, and can be treated for routine medical conditions. After surgery, the cat recovers for a day or two  and is then returned back to the colony where people provide food, water and shelter. (Kittens and tame cats are moved into foster homes where they are loved, nurtured and socialized until they are well enough to be adopted.) Since the cats are no longer reproducing, the colony will gradually diminish in size. By reducing or eliminating mating, fighting and wandering, TNR makes the colony more stable, reduces the influx of newcomers, and improves the health of the cats.

    

Why Trap, Neuter and Return (TNR) Works

TNR works only if entire colonies are stabilized. Trapping 95% of the cats in a colony will not stabilize the colony. By stabilizing entire colonies at each food source, in the end, all food sources will be used for sterilized cats. Unsterilized cats without food sources will not survive.

*All sterilized feral cats have tipped ears. This makes it possible for caretakers to differentiate between cats that have already been spayed/neutered VS the ones that have not.

Why Does Trap and Kill Not Work?

Many animal control agencies will tell you that trap and kill is the only way to control the unwanted cat population and they have proceeded to kill all feral cats that they can. The fact is that after almost 100 years of killing there are still feral cats. That alone should be proof enough that is doesn’t work.

Reasons why Trap and kill does not work:

  • Removing cats from an area only allows another colony to move into its place in order to take advantage of the food source that once supported the first colony. Essentially you would have to trap and kill everywhere, all at once, to catch all the cats. The TNR option allows you to stabilize one area at a time. Once the cat population of a colony is stabilized, the colony will defend its territory and keep other cats from moving in. Working one area at a time allows you to clean up entire regions, and someday the entire state because all food sources will be utilized for sterilized cats.
  • To many people, killing the feral cats is not acceptable. Many people, especially the elderly living alone, welcome the company of the cats each day. Others rely on the cats for rodent control in places like farms, behind restaurants where dumpsters are located, and houses backing to wooded areas. Without a trap, neuter and return program these people have no alternative but to let the cats continue to breed. They may catch a few kittens from each litter and give them to the animal shelters to be rehomed. What they don’t realize is that more than 50% are destroyed after five days. Those that are not caught are left to breed, at will, and the population of a feral colony can double, literally overnight. The problem only gets worse, the feral cats are less healthy and have the potential to spread diseases such as Feline Leukemia (FeLV) and Feline Immunodeficiency virus (FIV).
*All feral cats treated in TNR programs within the last 8-10 years should be ear-tipped. There are still some very rural areas that do not employ the “ear tip” method most commonly associated with feral cats. There may even be some tame cats within feral colonies that are sterilized but may not be ear tipped because they are tame and not truly feral.
