Trap Setup: 3 Points, Bait, a 4-Hour Limit

A trap is a 10-second tool and a 4-hour responsibility: the door drops, and what happens in the next 4 hours decides whether the cat goes back healthy or goes to a clinic with a split claw. Set 3 points, expect the cat to walk in 45 to 90 minutes after you step away, check every 30 minutes, and never leave a set trap past 4 hours. Call a local rescue group before your first night even where nothing local requires it: they lend 2 to 5 traps and know which clinic admits a cat at 8 am.

Point 1: against a wall, on the path

Cats walk edges, not open ground. Back the trap against a wall or hedge line, door 1 to 2 m past a corner the cat already rounds. Leave 20 to 30 cm between trap and wall, and point the door the way the cat comes from, not at the wall. A trap set in the middle of a lawn reads as a hole with a smell in it and gets skipped 9 nights out of 10.

Wire under the paws stops cats at the threshold: a 30 cm square of newspaper over the trip plate gets them across in 10 seconds.

Point 2: the sheltered entry

Under a stairwell, inside a porch, behind a hedge gap: anywhere the colony sits when it rains. Pick a spot 2 to 3 m from a door and 1 m from a wall, and check that wind does not blow into the door. Wind carries the bait away, and a flapping sheet keeps a nervous cat out for hours.

Weather sets hard limits. Above 30 C the trap needs shade from 10 am to 4 pm; below 5 C it needs a cardboard base and a doubled cover. A cat at 33 C in direct sun is in trouble in 40 minutes.

Point 3: the feeding station

Where the colony is fed, set the trap 3 to 5 m from the usual bowls and move the bowls past the door, so the cat must pass it to eat. Stop putting food down 2 hours before you set, 30 to 60 minutes before dusk. A trap at a feeding station catches in 20 to 40 minutes far more often than one on neutral ground.

Rotate the point every 2 nights: the same trap in the same 1 m spot stops working after 2 or 3 captures, because survivors watch the ones who did not come back.

Bait: 1 tablespoon, warmed to 30 to 35 C

Use 1 tablespoon of sardines or tuna in oil, warmed to 30 to 35 C in the sun or a warm-water bath, and place it on a paper plate 5 cm behind the trip plate. Then build a trail: 3 to 4 pea-sized pieces on the paper from the door to the plate, so the cat is eating at step 2 and never looks up. Warm bait throws more scent than cold at 10 C, the temperature most trapping nights happen at.

Three baits that fail: milk, which pulls cats in and then gives them diarrhea; dry food alone, which they hook out with a paw from outside the trap; and a full bowl, which feeds the cat and removes the reason to enter. Fried chicken works too, and so does the colony's usual wet food: a new smell is a new risk to a cat that has learned 2 or 3 traps.

How long to wait, and when to move

Most cats enter 45 to 90 minutes after the trapper walks away, so the first check belongs at 30 minutes. Check every 30 minutes, cover on trip, and pull at 4 hours: a cat that has smelled a set trap for 4 hours will not enter on hour 5. If a night passes empty, leave the trap closed and unset in the same spot for 1 night so it stops being news, then set it again 2 to 3 m away.

Two empty nights at 1 point means the point is wrong, not the bait: move 3 to 5 m before you change the menu.

Setup point	Distance to cover	Set window	Check every	Expected wait
1 Wall line	1 to 2 m	30 to 60 min before dusk	30 min	45 to 90 min
2 Sheltered entry	1 to 3 m	60 min before rain stops	30 min	60 to 120 min
3 Feeding station	3 to 5 m	2 h after last feed	20 min	20 to 40 min
No-go: open lawn	0 m	never	n/a	0 catches in 9 nights

The 5 rules that end a night early

Rule 1: no traps in rain. Water ruins warm bait in 20 minutes and a cat will not step on wet wire; set 2 hours after the rain stops, on dry ground. Rule 2: no trapping a cat you have kept off food. Fasting is tied to surgery time, not a way to sharpen appetite; a 2.5 kg cat already 14 hours empty can crash in the trap, and the fast and every drug belong to the veterinarian.

Rule 3: no kittens. A cat under 1 kg or 8 weeks goes out of the trap at once, at the capture point, without an overnight hold. Rule 4: no nursing queen. Check the belly: 4 to 6 enlarged, pink nipples mean kittens within 50 m, so release and come back in 4 to 6 weeks. Rule 5: no occupied trap in a car above 25 C, and never carry it by the door; lift level with 2 hands.

The 60 seconds after the door drops

Cover the trap within 60 seconds with a dark sheet, say nothing, and lift it level into the car within 5 minutes. A covered cat stops pacing in 3 to 5 minutes; an uncovered one can break a tooth in 10. Do not open the trap to check the sex, and do not add food. Drive with 1 window cracked 2 cm, no radio, and keep the ride under 30 minutes.

If the clinic cannot take the cat for 6 hours, keep the trap covered at 18 to 24 C, off the floor, with no food.

Handover and the 24 hours after

Hand over the trap, not the cat, at 7 to 9 am, labeled with the trap number, the capture address, and your phone. Ask 2 questions: what aftercare they want, and when release is due. Friendly cats go to adoption checks, not back to the block; anyone moving within 2 weeks should not set a trap. Expect 24 to 48 hours indoors, checks at 3, 8, 20, and 24 hours, and release within 100 m of the capture point at dusk.

Wash the trap with hot water and pet-safe detergent before reuse; one that smells of the last cat catches nothing for a week.

The 5-item night checklist

Confirm 2 rescue-group traps and 1 clinic slot before dusk.
Set 3 points: wall line, sheltered entry, feeding station; 1 trap each.
Bait 1 tablespoon warm fish plus 3 to 4 pieces as a trail.
Check at 30 minutes and every 30 after; pull at 4 hours regardless.
No rain, no fasting, no kittens under 1 kg, no nursing queen, cover in 60 seconds.

Three points, 1 tablespoon, 30-minute checks, 4 hours: the system fails most often because someone set 1 trap on open grass.

Frequently asked

How long should I wait before moving the trap?

Expect a cat to enter 45 to 90 minutes after you walk away, so check at 30 minutes and every 30 after that. Pull the trap at 4 hours, and if a whole night passes empty, move the point 3 to 5 m along the wall before you change the bait or the schedule.

What if it rains on trapping night?

Do not set. Rain soaks warm bait in 20 minutes and cats will not step on wet wire, so the night is wasted and the trap smells wrong for the next attempt. Wait 2 hours after the rain stops, set on dry ground, and use a doubled cover if the low is under 5 C.

Should I withhold food so the cat is hungry?

No. Fasting belongs to the clinic and is timed to surgery, not used to sharpen appetite; a 2.5 kg cat already 14 hours empty can crash in a trap. Stop feeding 2 hours before you set, use 1 tablespoon of warm fish, and let the veterinarian decide the pre-surgical fast.
