Transit Emergency Carrier
An old pet carrier with straw as a transitional shelter under cover, for example after trapping or during relocation. The grille and slots let wind through.
- It must stay dry.
- It must be raised off the ground.
- It is not a replacement for a durable waterproof shelter.
- Inspect it every day.
- Replace it as soon as it gets damp or deforms.
This model has no 3D view; the drawing and dimensions below fully describe the construction.
- For someone who has to protect an animal tonight with whatever is at hand.
- For one cat, including community cats.
- As a permanent shelter: this is emergency-only and must be replaced as soon as possible.
- Outside without a roof above it: it must stand under a canopy, in a shed or a doorway.
- For young, old, sick or unacclimated animals without extra protection and supervision.

What you have and what to obtain
Quantities come from the model geometry; items marked as assumptions are planning allowances. Reused material must pass the checklist.

Weather exposure
A warm shelter that gets damp can be worse than a simpler one that stays dry. This is an explanation, not a condensation calculation.
- Ground contactRaised about 80 mm off the ground.
- Rain splashRain splash from the ground can reach the floor and lower edges; protect the edges.
- Roof drainageThe lid is flat: water runs off to the sides. It must close well and the entrance must not sit below a drip edge.
- Rain at the entranceLow sill: rain and snow get in more easily; turn the entrance away from wind.
- DryingWithout a service opening drying and cleaning are harder; change bedding through the entrance.
- Absorbent materialInterior surfaces do not absorb much moisture.
- Maintenance accessAccess for checks and cleaning is simple.
Check the spot
This is not a safety certificate for the spot: it only means none of the listed questions is ticked.
What goes inside
- RecommendedStrawRepels moisture and stays loose. Replace when damp, compacted or soiled, and when seasons change.
- AcceptableBlanketAbsorbs and holds moisture; a damp blanket chills. Wash and swap as soon as it is damp.
- AcceptableTowelAbsorbs moisture like a blanket. Wash and swap as soon as it is damp.
- AcceptableWashable dog bedDepends on fabric; textile absorbs moisture. Dry or swap as soon as it is damp.
- Not recommendedHaySoaks up moisture, turns cold and can mould. If already in a shelter, replace it with straw.
- Not recommendedWood shavingsPartly absorbs moisture. Change when damp or compacted.
- Not recommendedNo beddingNothing to absorb moisture. Not applicable.
Inspection schedule
- DailyCheck that the straw is dry and loose; replace it when damp or compacted.
- DailyCheck for water or dampness on the floor and walls, especially under the entrance.
- After stormsAfter rain or snow check the interior and the ground under the shelter.
- DailyCheck the plastic for cracks and sharp edges around the opening.
- Each seasonQualitative: plastic and foam become brittle in sunlight; replace them when they fade or crumble.
- DailyCheck that the lightweight shelter is still weighted or secured.
- After stormsClear snow from entrances and exits so the animal cannot be snowed in.
- WeeklyClean the interior; service access must allow cleaning without dismantling.

Prepare the container
Take a dry, clean old pet carrier. Close and secure the sides so the box cannot open.
Cut the entrance
Cut a 200 mm × 220 mm opening through old pet carrier, with the sill 30 mm above the floor so rain and snow stay out. Face the entrance away from the prevailing wind. Cover or sand sharp edges.
Raise the shelter off the ground
Set the shelter on four stable bricks, about 80 mm above the ground, so the floor does not touch cold, wet ground. Check that it does not rock.
Add straw, not hay
Loosely fill straw to a quarter or half of the interior height. Do not use hay, towels or blankets in an outdoor winter shelter: they absorb moisture and chill.
Choose the spot and secure it
Set it against a wall or fence, out of the wind, away from roof runoff and roaming dogs. Weight or secure lightweight shelters. Check the spot with the placement checklist.
Check every day
This is an emergency solution only. Check daily that it is dry; as soon as the cardboard gets damp or deforms, replace it. Move to a durable waterproof shelter as soon as possible.
