Trap-neuter-return explained

Trap-neuter-return, often called TNR, is a way to manage outdoor cats that have no owner and fear people. A trained person humanely traps the cats, a vet sterilises and vaccinates them, and the cats go back to where they were found. Over time the colony stops growing. Local groups run most TNR work, and local rules vary, so start by contacting one.

What TNR is and why it is used

A feral cat, or community cat, lives outdoors and usually will not accept handling. A colony can grow fast, because a female cat can have several litters a year. Kittens born outdoors face disease, cold and traffic.

In the past, many places tried to remove and euthanise colonies. New cats then moved into the empty territory, and the problem returned. TNR keeps the established cats in place and stops them breeding. Neutered cats fight less, wander less and stop the noise and smell of mating behaviour such as yowling and spraying. Over time the colony shrinks as older cats die and fewer kittens are born. Programmes also remove very friendly cats and kittens young enough to be socialised and place them for adoption.

TNR is widely backed by animal welfare organisations. It has critics, including some who worry about wildlife predation by outdoor cats. Debate continues, and policies differ by place. Local councils may support, tolerate or restrict TNR and feeding. Ask your local group what applies.

What happens, step by step

1. Find your local group or clinic. Many communities have a TNR organisation, a humane society or a low-cost clinic. They can lend traps, train you, book surgery and advise on law. Do not trap before you have a clinic booked.
2. Learn the colony. Count the cats, note their markings, and learn when they eat. Feeding at the same time each day helps. Check whether any cats already have a tipped ear.
3. Plan the date. Book the surgery slot first. Remove the cats' food for the period the clinic requests, often a day, so they will enter the trap for bait. Follow the clinic's instructions on timing.
4. Trap. Use a humane box trap. Place bait such as strong-smelling canned food at the back. Check the trap often and stay nearby. Never leave a trapped cat alone for long, and do not trap in extreme heat or cold. Cover the trap with a sheet as soon as the cat is inside, which calms it.
5. Keep the cat in the trap. A feral cat should stay in the trap until surgery. Do not open it, even to look. Keep it somewhere quiet, warm and safe from other animals and weather.
6. Surgery and care. A vet spays or neuters the cat under anaesthesia, usually gives a rabies vaccine and other vaccines and checks for obvious health problems. The vet may treat ear mites, fleas or wounds. In many places the vet also removes the very tip of one ear, a mark that tells people the cat has been sterilised. A microchip is sometimes added. The vet decides what treatment each cat gets.
7. Recovery. The cat usually stays in the trap for a day or two after surgery, depending on the clinic's advice. Keep it covered, quiet and warm. Follow the clinic's written instructions about food, water and when to release.
8. Return. Release the cat at the place you trapped it, as the clinic advises. Open the trap door facing the colony's area and step back.
9. Keep caring. Provide food at a regular time, fresh water, and insulated shelter in cold weather. Watch for new cats and for sick ones. Take new arrivals through the same process.

What about kittens and friendly cats

Kittens under about eight weeks old are in the socialisation period and often can be tamed and adopted. They are too small for surgery, so a rescue may foster them until they are old enough. Older kittens and adult strays that are friendly can be placed with a rescue instead of being returned. Ask the group which cats should stay and which should go.

Safety for you

Feral cats can bite and scratch if cornered. Use a trap and a long cloth to cover it, and keep hands away from the door. If you are bitten or scratched, wash the wound well and seek medical advice, since cat bites can become infected and some places have rabies risk. cat bite abscess is a risk for cats too.

What TNR does not do

• It does not make wild-living cats safe from traffic or weather.
• It does not remove existing cats at once. The colony shrinks over years.
• It does not work well if only some of the cats are trapped. Aim to catch the whole colony.
• It does not replace responsible pet ownership. Spaying and neutering owned cats helps stop new strays.

Common mistakes

• Trapping without a clinic booked. The cat sits in a trap with nowhere to go.
• Releasing a cat in a new place. Cats returned to a different area often get lost or are chased off by others.
• Leaving a trap unattended. A trapped cat can overheat, panic or be attacked.
• Skipping the follow-up. New cats join, and colonies need caretakers.
• Feeding without sterilising. More food supports more kittens.
• Trapping a pet by mistake. A friendly cat or a cat with a collar may be owned. Check for tags and ask around.
• Ignoring local law. Some places require permits or limit feeding. Ask your council or group.

When to get help

Call the clinic or a vet at once if a trapped or recovering cat:

• breathes with an open mouth, or struggles to breathe
• bleeds, or its surgical wound opens
• is limp, cold or cannot stand
• has not passed urine for a day or more, or strains, especially a male
• shows signs of serious injury
• is a kitten that is cold and limp

Do not give food, water or medicine to a recovering cat unless the clinic's instructions say so.

Summary

• TNR traps, sterilises, vaccinates and returns community cats.
• It stops breeding, reduces nuisance behaviours and shrinks colonies over time.
• Work with a local group, and book surgery before you trap.
• A tipped ear shows that a cat has been through TNR.
• Take young kittens and friendly cats for socialisation and adoption.
• Keep caring for the colony after return.
• Local law and policy differ, so ask first.
