There is no “match percentage”: each result shows the checks it passed and the compromises it carries.A box of checked old boards with EPS and a thin interior lining. Boards of unknown origin, with oil or old preservative treatment, are rejected.
A tote raised off the ground, with a high entrance sill and loose straw up to half the height. An inexpensive winter option for one cat until an insulated shelter is built.
A foam box placed inside a larger tote: the plastic protects the foam from rain, sun and outside scratching while the foam insulates. The entrance is cut through both, aligned.
The Alley Cat Allies method: a large tote of about 30 gallons, a foam slab on the bottom, a smaller tote of about 20 gallons inside and straw, with one entrance through both.
A tote lined inside with 30 mm EPS on every side and under the lid. The foam must be covered by straw and checked for scratching.
The same tote as the EPS variant but with XPS boards that tolerate moisture and pressure better. Useful when you have XPS offcuts from construction.
A tote-in-tote with foam panels also in the gap between walls, not only on the bottom. More work and material than the basic version, with a more complete insulation layer.
An OSB/3 box with EPS and a thin lining, roofing felt and a roof falling to the rear. Sealing the OSB edges is mandatory.
An OSB box with 50 mm EPS, one entrance and enough room for two cats to curl up together.
The same module built in batches and stacked at most two high when secured. A small 20 mm roof fall still sends water to the rear.
Heated variant of the compact single-cat shelter, with a coordination zone for a purpose-built heating product and a required unheated choice area.
Compact insulated winter shelter for one adult cat, with reserve capacity for two cats that voluntarily share it.
Heated single-chamber variant for two adult cats, with a purpose-built heating provision zone and remaining unheated floor area.
Single-chamber winter shelter for two adult cats with restrained interior volume and an elevated base.
Two separate chambers, each with one entrance, for cats that do not share a space or to keep an escape option per entrance.
Exterior plywood, 30 mm XPS and an interior lining. For two cats that get along, without the framing and hardware of the engineered models.
Two chambers for two cats each in one OSB box, close to the Alley Cat Allies suggestion of about 2 × 3 ft for a small group.
Heated two-chamber variant with space for a compatible purpose-built heating product and an unheated choice zone.
Two-chamber shelter for four adult cats, with one chamber per pair and two independent entrances.
Three chambers with one entrance each and a service roof for cleaning. A budget alternative to the engineered Alpine Colony Six.
Three-chamber shelter for up to six community cats. Multiple chambers reduce the whole group's dependence on one entrance.
Heated three-chamber variant for up to six community cats, with one separate heating provision zone in each chamber.
Four-chamber reference model for rescue/community use, designed as a repeatable modular segment.
Heated four-chamber rescue/community variant for up to eight cats, with a separate product-specific heating zone in each chamber.
