3” how to enter a drop trap – for cats” (as demonstrated by Nicki)
4Why use a drop trap? Easy to transport and use Easy to catch multiple cats in single trapping sessionless time consumingespecially important for clinic eventsNo “snap” noise; less traumaticExcellent for snap-trap-wary cats/sites
5Making a drop trap – what you need Supplies:Collapse-able black wire dog kennel (large or extra large; single door)2 Railings – plastic posts for electric fencing (metal and wood make too much noise)Small 3/8”” cutting board – acrylic is best, it slides quietly (wood swells and is noisy) and preferably black½ “ softwood dowellingCopper wire – 20 gaugeString and handle/stickTools:Power drill and drill bitsWire cutters for thick wireRotary tool or metal file (for sanding down rough metal edges)Needle nose and regular pliers with fine wire-cutter feature
6Dog Kennel use the clip to keep it closed during transport ensure it is collapse-able for easy transportuse the clip to keep it closed during transport
7Creating trap doorUsing wire cutters, cut space for trap door on the end of the cage opposite the manufacturer’s doorDetermine width and height of space to be cut. Dependent on the spacing of the vertical rails on the dog kennel the best width between the rails is centimeters, height about 25 cm. The cutting board (step 13)may need to be cut to size so that it will glide easily in railings (railings are wired to the vertical bars of the black-wire dog kennel)On large kennel, it is generally vertical bar #8, 9, 10 and 11 counting from left sideRequires some jigging as cages may be slightly different designsA space wider than 18 centimeters gives trapped cats too much room to push against causing the door to pop outEnsure height of space to be cut allows cat to enter freely (about 25 cm.)File cut edges smooth to avoid injuring cat (use rotary tool or metal file)
8RailingsUse plastic molded posts, made for stringing electric fencing. Purchase at farm supply store – need twoCut off spiked portion. Measure length required for railing based on height of cageVery top piece becomes “footing” for railings; dispose of spike endNotice the molded sides – it is up & down these sides that the cutting board slides to operate as the trap doorSome posts have molded nubs
9Aligning railings Railings are molded Cut two pieces of ½” dowel to secure rails to each other, one for between the top of the rails and one for use at the bottom (not in pictures)Drill holes in railing-back, and use brass wire to connect railings to dog-crate so that cutting board slides smoothly between rails and “foot” is on the bottom rungThere are plastic hooks on one side of the railings – try to hook at least one or two of them over the horizontal bars of the dog kennel. You may have to break the rest of the hooks off so the railing fits snugly to the vertical wire of the dog kennel.
10Cutting board glides up and down easily in railing Note hooks on railing are on the inside (1 or two over vertical bars of cage where possible)
11File smooth any cut edges Do not leave any rough edges where wire cutters have been used – may injure cats
12Attaching railings“top” of electric-fence post railing becomes “foot” (so door won’t fall out during transport)Use plastic or metal wire to attach posts to vertical bars of dog cageAt foot and top of railings the wooden dowels os cut and attached to hold rails parallel to one another1.2.
13Creating trap door, con’d Drill small hole in top of cutting boardTie string to cutting board through hole; drop board between railings and ensure smooth gliding (string at top)Run end of string through and over a horizontal rung near the top of dog cage (string facing trapper)Wind extra string on handle or stickYou now have a drop trap!
14Note:String in this picture is attached to top of cage with handle – this is not the string position you use during trappingThis trap has not a dowel at top and bottom of the rails. The dowels add a bit more stability to the plastic rails
15Using a drop trap - outline Advance placement and caregiver instructionsOn the dayCamouflage/hidingTrapping procedureRemoving the cats from the trap
16Advance placement and caregiver instructions One to two weeks before trapping, place drop trap and transfer cages (towels inside) on siteTie door up with duct tape or twist tie to ensure it is in open positionEnsure trap is in a position from which you can trap so that nothing will look different on trapping dayPlace it at or close to normal feeding spot, ensuring there is a camouflage spot within manageable length of string (car, nearby room, etc.)Ensure trap door is facing spot where trapper will hide. When cats are eating they are facing away from the door.Transfer cages need to be in a manageable spot.
17Advance placement and caregiver instructions, con’d Instruct caregiver to feed daily only in the trap, just inside manufacturer’s back doorLeave water outside trapDetermine what time of morning (or evening) caregiver normally feeds (so you can arrange to trap at that time)Encourage morningsBeg caregiver for consistent feeding time in the period leading up to trapping
18Instruct caregiver to feed in back of cage – multiple dishes across back if multiple cats
19Advance placement and caregiver instructions, con’d Instruct caregiver that last feeding occurs 24 hours before trapping eventCall day before to emphasize and reaffirm trapping timeWarn neighbours to keep pets in on trapping day, and to not leave food out for strays during the 2 week acclimatization period (this is so target cats will be forced to go in drop trap to eatOtherCheck in with caregiver in interim - preferably in person - to ensure instructions are understood and being followedPlace one or two snap-traps (open) on site with feeding instructions (optional)
20On the day - camouflageSeeing trappers and their movements will alarm the cats-minimize movement: move quietly: wear “quiet clothes”If there is a natural hiding spot, plan to use it- examples: saddle room: behind patio door and curtainsAny out-of ordinary movement or sound will keep cats away – no talking, no whispering!If two trappers, pre-agree on hand-signals and movementsIf no natural hiding spot, use car with blacked-out windows (ask caregiver to park a car in the designated trapping spot during acclimatization period, so cats will be used to it being there). Staying still and slumped low in the car will often work without black out windows.
21Camouflage for car ... if necessary Trap out of passenger side if possible (avoid steering wheel)Cover any windows where movement can be seen –front window and trapper-seat window(s) at minimumMaterialBlack poster boardLandscape clothUse black screening for sight-lineCheck:Door still opens.Don’t close it tight so you can leave car quietly when cats are in the trapString can move unencumbered
22Landscape cloth with screen over sight-line – front of car
23Landscape cloth with screen over sight-line – passenger side Note string under cloth (window is open)
25On the day - camouflageEnsure care giver is quiet and acting naturally (from cats’ perspective)No guestsNo kidsNo talking/peeking/exclaiming
26On the day – trapping procedure Bait and set any snap-traps on the siteEnsure covers are sitting on top of drop trap (in-place to drape quietly when cats are trapped)Ensure drop trap is properly closed and secureHave caregiver put choice food in back of drop trap (cat is used to seeing caregiver do this)Ensure care-giver moves out of sitePull door up and, with string taught, assume hiding position; ensure trappers are out of siteWait for cat(s)
27Erecting cat trap on site: Sometimes loops on drop trap cage will come loose; secure with twist tie or wire when trapping
28On the day – trapping procedure When cats enter trapThey will be facing away from the trappers; let cats feed and let other cats enterOnly begin to drop door when one or more cats raise head(s)Drop door SLOWLY and imperceptibly – cats should still be feedingDo not leave hiding spot until cats are aware door is shutOne person
29On the day – trapping procedure When door is shut, move slowly and quietly to drop trapDrape covers over drop trap to quiet cat
30Ensure drop trap is completely covered while cats calm down Ensure drop trap is completely covered while cats calm down. If they are not quiet the covers are too thin or there are still holes they can see through. Someone should have a hand on the top of the door while preparing transfer cages. (Wily cats can lift the door)
31Remove cats from trap one at a time Place transfer cage door aligned with closed trap door of kennel (note - towel on floor of transfer cage and cover are missing in this picture)Drape transfer cage with cover to create dark spaceLift cover from back part of drop trap to create light – cat will generally want to go from light to dark, and will be attracted to transfer cageHave foot or block behind transfer cage to avoid transfer cage movement (cats may move quickly and forcefully)
32Removing cat from cage, con’d lift transfer cage door, aligned and ready to close quicklyLift drop trap door by string, keep fingers hiddenWhen cat moves in, close drop trap door and transfer cage doorLock transfer cageMove transfer cage, covered, to vehicleResume transferring next cat, or resume trapping
33Removing cat from cage, con’d Tips and techniques:Second person recommended for transferring from drop trap to transfer cage (trapping companion or caregiver)Some cats have trouble finding trap door for escape to transfer cage and need guidanceSometimes just the feet of someone at the big door end will make the cat moveUse blunt-end poking sticks (preferably 2) to guide cat to door (broom handle, etc.)Some cats are looking for escape (ie light),not darkCreate light at end of transfer cage (tunnel effect)Remove cover from drop trap
34Other tips and techniques Lifting covers slowly to peek, have caregiver examine cats in transfer cages for gender, pregnancy, illness etc. Label cage with this info, and/or make noteRelease any cats not needing trappingAlready ear-tippedNeighbourhood petsDon’t forget to tend snap-traps if in use; move quietlyAlways close car doors quietly
