A basic box trap is a painless and humane method of safely capturing cats. Regardless of the level of socialization, do not attempt to pick up a cat to put her in a carrier. Use a humane box trap or drop trap to ensure the safety of the cats and you. We do not recommend “clam” traps, as they can injure cats (instead, use drop traps for trap-savvy cats). Never use darts or tranquilizers to attempt to catch a cat. These methods are also dangerous and stressful to the cats.

 

  1. Make sure you have enough traps for the entire colony—one trap per cat and a few extra in case a trap malfunctions. If your goal is to trap a colony of 20 cats, then set about 25 traps on your first attempt. If you do not have access to that many traps at one time you will have to trap the cats in shifts.
  2. You may be able to borrow some traps in your area, from a local Feral Friend or animal shelter. Always determine an animal shelter’s policy toward feral cats before borrowing—some may require you to return the trap and the cat.
  3. There are several companies that make and/or sell humane box traps. The companies listed below are some we have come to trust and use after decades of testing and trapping, though they do not represent a comprehensive list. Experienced trappers have their own preferences. If you borrow traps from local caregivers or trappers or a Feral Friend, ask them to teach you how to work with each specific trap.

  4. Research the correct size trap. The standard size traps for feral cats are usually referred to as the “cat” size. Trapping tom cats may require the larger “raccoon” size trap; these should not be used for kittens, as they are too large and powerful.
  5. Always put kitten safety first when trapping by using the correct traps. You should have one trap per cat so that the kittens are less likely to follow each other into a single trap. Kitten traps exist, but Tomahawk 606s work as well. You can manually spring the box traps with string and a water bottle to ensure that no kittens are by the trap door when it’s triggered.
  6. Look for the right features and consider additional equipment needs.


  • Back Door - One of the most important features in a trap is a back door that shuts like a guillotine. This is essential when handling a cat you cannot touch.


  • Transfer Cage - Once you have caught a cat in a trap, leave her there. But if you must put her in a different cage, such as a holding cage, use a transfer cage with a matching guillotine door and conduct the transfer in a closed room.
  • Isolator (aka catacomb or trap divider) – This looks like a large pick (or comb). The isolator is inserted into the top of a trap or cage to force the cat into a small portion of the cage for anesthesia. (This device can be used in place of a squeeze cage by your veterinarian.)
  • Feral Cat Den (aka Feral Cat Handler) - When you must hold a cat for several days for recovery from an injury or extensive surgery, the den provides a quiet hiding place. The den can be placed in a larger holding pen or large cage where the cat is being held, along with a litter box, food, and water. The cat enters the den by a porthole on the side that you easily slide shut once the cat is inside. You can then take the cat for cleaning, treatment, or transportation. A vertical sliding door makes it easy to transfer the cat to another cage or return the cat to the den for recovery after surgery.
  • Drop Traps - If you are dealing with a particularly hard-to-trap cat, you may want to consider building a drop trap.  Drop traps allow you to catch a cat without having to force it into a confined space. These traps are generally large, mesh covered squares that, when triggered by you with a rope, fall down over the cat. All drop traps allow you to easily transfer the cat from the drop trap to a regular humane trap. Using a drop trap is often a last resort, because it either requires you to build your own or find one to use. Most drop traps are cumbersome enough to require the help of another trapper.

  • Kitten Traps - It's a good idea to have at least one of these smaller traps on hand in case you see kittens during your trapping efforts. Smaller kittens are sometimes too light to trip the plate in full-size traps.


Other Items for Trapping


In addition to traps, you will need a few essentials:

  • Bait for traps: Several large pop-top cans of tuna, mackerel, sardines or other smelly bait, preferably oil packed (if you don’t bring pop-top cans, be sure to bring a can opener)
  • Plastic forks or spoons (to scoop out the bait)
  • Newspapers, which will be used to line the bottom of the traps 
  • Tape to hold newspaper to trap floor, if necessary (especially for windy days)
  • Trap covers: Enough big (i.e., beach size) towels, blankets, or sheets to fully cover each trap after cats are caught
  • Trap labels with room for the date, cat description, exact location where the cat was trapped, and room for any observations, such as noticeable injuries.
  • Small food storage container (big enough to hold open cans of tuna still in use, to prevent spillage)
  • Dry and canned cat food and water (to leave after trapping for cats not trapped)
  • Trash bags (for tuna lids, used plastic silverware, etc.)
  • A roll of paper towels
  • One pair of thick gloves per trapper (wear these for your safety while carrying cats in traps)
  • Antibacterial hand wipes, baby wipes, or antibacterial gel (for cleaning yourself, the traps, and any messes)
  • Tools such as pliers and some WD-40 for traps that might not work properly
  • First-Aid kit 
  • Bungee cords (to secure traps in your car so they don’t slide around)
  • Feral Cat Colony Tracking System and pen or pencil and clipboard
  • Cardboard, large plastic trash bags, or towels to line the inside of your vehicle. Puppy pads also work well, should there be accidents.
  • Binoculars and camera
  • Flashlight
  • Drinking water and snacks (for you)
  • Appropriate weather-related clothing and practical shoes
  • Alley Cat Allies brochures (to pass out to people who stop by to ask what you’re doing)
  • Patience. Trapping can be time-consuming and, at certain moments, a bit stressful. If you remember to stay calm and follow the plan that you’ve devised, you will be successful!
