TRAP-NEUTER-RETURN (TNR)

Frequently Asked Questions:

Where should I get a humane trap?

You can borrow a trap from Tree House or if you plan on tackling a large colony, you may want to consider buying your own trap. At Tree House we use Tomahawk traps. Other quality traps include Havaheart Traps or Tru-catch Traps. Please call Tree House at 773.784.5488 ext. 0 for more information about our trap lending service.

 

How do I safely and humanely trap a feral cat?

You should familiarize yourself with the trap before attempting to use it. If you rent the trap from Tree House, we will show you how to use it, when you pick it up. It is important to NEVER leave a set trap unattended for more than a few minutes at a time. Ideally, you should watch the trap from a comfortable distance. When the trap is sprung, quickly move the cat to a safe area indoors.

On the Tomahawk trap and most other traps, the top has a handle. The front of the trap has a slanted door and the rear of the trap has a flat back panel. Some traps have two slanted doors and no flat rear panel. In that case, use either door.

1. Open the trap by lifting the wire handle that secures the trap door.

2. While holding the wire handle up, push the spring mechanism in and pull the door up until it is parallel with the ground.

3. Put your hand under the door to hold it up, and pull the arm that runs the length of the trap downward and toward the open door.

4. Place the small hook at the end of the arm closest to the open door in the notch to set the trap.

5. When the trap is set, the trip plate will be slanted upwards. When the cat walks into the trap, he must step on the trip plate to cause the door to shut behind him.

6. If you plan ahead you can feed the cat inside the unset trap for a week or two. All you have to do is secure the door in an open position by using twist-ties or twine. This way the cat will be more likely to enter the trap when it is set.

7. If trapping in a public place, we recommend placing signage on the trap to alert others of your good intentions.

8. It is a good idea to cover the trap with an old sheet, blanket or towel. This will help the cat to feel safe and will prevent him from trying to snatch food through the outside. Tuck the cover underneath the trap to prevent the wind from causing it to flap and scare the cat.

9. Line the trap floor with newspaper or a towel. Cats don't like the feeling of wire mesh between their toes.

10. Put the trap as close as possible to where the cat is accustomed to eating. Put the food at the opening of the trap the first day, and gradually move the food plate back a little each day until it's near the trip plate.

11. Plan to trap the night before or early the morning of your appointment.

12. Place a small amount of food underneath the trap, and behind the trip plate. This will ensure that the cat must step on the trip plate to get to the food, and will eliminate the need to remove the food from the trap after it has been sprung.

13. Make sure that the newspaper or towel does not prevent the door from closing.

14. When the cat steps on the trip plate to get to the food beyond it, the trap door will shut securely behind him.

15. Immediately move the cat to a safe, quiet, indoor environment, and keep the trap covered.

When is the best time of the day to trap?

Trapping early in the morning or at dusk are the best times but it is most important to trap during the times when you normally see the cat or feed the cat. You may want to withhold food for a day or two before trapping to improve your chances of luring the cat into the trap with food.

Trapping at night is risky. You could trap opossums, raccoons, skunks or other wildlife. If you accidentally catch one of these animals, release them immediately.

Where do I keep the trapped cat the night before the veterinary appointment?

Keep the cat indoors where he will be safe from predators and the elements. Safe places include garages & sheds, inside a spare room in the home, in an automobile (crack the windows for ventilation, and only use vehicles if the temperature outside are not too hot or cold). If you don’t have much space consider keeping the trap in the bathtub. Set up the area by lining the ground with a plastic sheet or tarp with newspapers on top. Make sure that all entrances to the room are closed.

How do I get food & water in the trap?

Do not give food to the cat the night prior to surgery. Cats should have an empty stomach to prevent nausea caused by the anesthesia. Water should be provided at all times while the cat is not in transport. You can insert a small bowl of water into the end of the trap by slowly opening the back door and sliding it in. Feral cats will be afraid and will likely cower and hiss at the back of the trap. In any case, it is important to keep a close watch on him and to quickly close the door when finished. Most importantly, always avoid direct eye contact with the cat which he will interpret as a sign of aggression. Before transporting the cat to his appointment, remove the water bowl just as quickly and carefully as you placed it inside or you can use a wire hangar to spill the water out onto the newspaper if you don’t want to open the door again.

After surgery, an unbent wire hangar may be used to slowly upright overturned bowls. Use a water bottle to fill the water bowl and slide in filled food bowls or drop the food in through the holes in the trap. A funnel may also come in handy.

How do I fit a litter box in the trap?

With an adult cat in the trap, adding a litter box does not leave much space for food or for the cat to lie down. Those with small kittens may fit a small 9"x9" aluminum baking pan or a similar small container filled with litter through the rear of the trap (the side with the flat back panel). Feral cats/kittens may or may not use the litter box.

It's easier & more convenient to let the cats eliminate onto the newspaper beneath the trap. They will usually use the back of the trap, since their food is at the front. When it is time to clean up, place fresh newspaper next to the trap, pick it up and place it on the fresh newspaper. Roll up the soiled paper and toss it in the garbage.

After the cat has been released, the traps will have to be disinfected. Hose & bleach them down outside your home, or you can bring them to a carwash.

Can I trap during winter?

Yes. Winter is a good time to trap because there is a lull in breeding, especially in colder climates like here in Chicago . If you can get a colony finished before February or March it will be well worth it. Peak breeding season starts in February.

How should I care for the cats after surgery?

The cats must be kept warm and dry since they will not be able to regulate their body temperatures after surgery. Ideally, they would be kept at room temperature. If that's not possible, they can be kept in a garage or shed with blankets wrapped around the traps, leaving an opening for air circulation. You can also stuff a towel or small blanket in the trap as an extra comfort. You may want to use portable heaters and heat lamps in cold weather conditions but be sure to keep them away from flammable objects.

It is also a good idea to elevate the traps off the ground a few inches by placing the trap on 2x4s or on a wide & sturdy bench or table, or put several layers of carpet remnants, cardboard or something similar on the ground and cover with plastic sheets, topped off with newspaper to provide insulation.

Remember to keep newspaper on the floor of the trap and under the trap to absorb waste. It is also extremely important to make sure that the cats get plenty of water to prevent dehydration and they should be eating well and eliminating before release.

How long should I wait before releasing the cats back to their territory?

If all goes well, we recommend keeping males for one day during warm weather and 2 days during winter. Females usually need at least one day more than males. Keep cats in their traps for the recovery period. General ly, if the cats are eating, drinking and eliminating regularly they should be ready for release.

Please understand that it is detrimental to the cat’s mental and physical health to keep them inside for any longer than necessary. Confining a feral cat for longer periods can be detrimental to the cat's mental, and therefore physical, well-being. As long as the sutures are still in place and there is no excess bleeding they should be ready to go in a day or two. If you have any doubts, please call Tree House or the facility where the surgery was performed. Be sure that the cats eat and drink plenty before releasing them since they may stay away for a few days after being released.

Should I trap a pregnant cat?

Yes, we recommend trapping and spaying pregnant cats. Remember, Animal Care and Control euthanizes more feral kittens than any other animals and we are flooded with kitten admission requests throughout the year. Female kittens may start to mate as young as four months of age, and the queens may start to mate again about 8-10 weeks after delivery. It is important to understand that the cat is not emotionally connected to her unborn kittens. She reproduces out of instinct. If anything, birthing kittens brings more stress to her life as she needs to work hard enough just to survive on her own. On the other hand, it would be traumatizing to her to take away her kittens after they are born and it is a lot of work to hand raise kittens.

If a cat seems very pregnant, or you know she is due within one week, there are some risks involved with spay/abortion but our veterinarians take extra precautions to make sure the surgery is done safely and we have never had a problem performing a spay surgery on a pregnant cat.

What happens if I trap my neighbor's cat?

If you happen to trap a neighbor's cat which is not sterilized, you will need to consider whether to spay/neuter him. Our advice is to talk to your neighbor and explain what you are doing and why you want to sterilize the cat. You can also add that by letting the cat outside that they are violating a Chicago City ordinance which proclaims that all domestic animals must be leashed or contained within the guardian’s property.

We know of some people who have sterilized neighbor’s cats and they report that most of the time, the neighbor was actually grateful. We know of no cases or lawsuits regarding the spay/neuter of a cat done by somebody other than the owner.

What if I trap a lactating queen (nursing mom cat)?

If a lactating female is trapped, the caregiver should check the area for kittens. If kittens are located, you can capture them by placing the trapped mother cat next to another baited trap. Some very young kittens can be caught without a trap, but they are often still too wild to be handled easily. It may be possible to capture them using a thick towel, but be careful they will bite and scratch. The same baiting method works the other way around. If lactating queens are captured and kittens can not be located, every effort should be made to release the mother cat within 24 hours so she can care for and nurse her kittens.

Our veterinarians will not perform spay surgeries on lactating females unless they are starting to dry up and their kittens can quickly be trapped and spayed/neutered as well. If you cannot find the kittens, try to re-trap the mom cat after she has likely weaned her kittens (about four weeks later).

What can I do about a very smart feral cat who will not go into a trap?

Some feral cats are very trap savvy. Some even eat in the trap without triggering the trip plate so all you can do is be persistent. If you have been trapping for a while without success, you might want to take a week off and then start over by getting the cat used to eating in the trap again as discussed earlier. Remember: Use a twist-tie or cable to secure the trap door in an upright position. Start by placing food at the trap's entrance. Each day, move the food back a couple of inches until the food is at the rear of the trap behind the trip plate. After a week of this, you’ll be ready to set the trap again. Again, you may want to stop feeding for a day or two to ensure success but be sure not to go for more than three days without feeding them and always provide water. If this still doesn’t work. Keep trying. Some cats take months to trap. Try again for a couple weeks and if you are not successful take a week off and try again. You can also make a trail of food or tuna juice from the entrance to the back of the trap. It also helps to camouflage the trap by covering it or putting it in a box or another enclosure. Sometimes a drop trap works best for hard-to-trap cats. Here is a link to building instructions from Alley Cat Allies: http://www.alleycat.org/pdf/droptrap.pdf

When should I trap kittens?

As soon as kittens are weaned form their mother’s milk and out walking around on their own they are ready to be trapped. This is usually when they are about 5 – 6 weeks old.

I think the cat may be friendly, should I try to pet him while he's in the trap?

Do not risk personal injury or undo stress on the cat by trying to pet him. These cats may look just like your feline companions but they are wild animals. If they feel cornered, or threatened they will try and defend themselves by attacking you. This does not mean that humans should feel afraid of feral cats outdoors. Feral cats avoid humans just like other wild animals. The only time they would try to harm you is in a situation where they feel cornered or threatened.

Will the cat be angry with me, and never come back?

The cat will probably stay away for a few days but after they have calmed down they will most likely visit more frequently and stay for longer periods of time.

If I trap a cat whose ear is already tipped, how do I know if he is up to date on inoculations?

That is hard to say. If there is another caregiver in the area you should check with them. Some people keep very accurate records for their colony cats and will be able to give you updated information. In any case, what you do depends on your circumstances: If you live in a town or municipality which monitors feral colonies for vaccinations, you should take the new cat in for vaccines.

If, as in Cook County , there are no legal requirements to having feral cats vaccinated annually, and the cat is not injured or ill, you should probably just release the cat.

Some feral cat caregivers trap and vaccinate their feral cats annually. If you can manage that level of care, that is great. For the time being, most TNR activists are just trying to sterilize as many cat as possible and that is OK, too.

Are feral cats given a one-year or three-year rabies vaccination?

At Tree House we give a 3-year rabies vaccination. Some clinics give the one-year vaccination but you can request three-year if you prefer.

Is it mandatory to give feral cats any inoculations?

It depends on the ordinances in your community. Whether or not it's legally required in your community, we recommend that you do it at least once because some protection is better than none.
