Overview
A two story outdoor cat shelter made from high density polyethylene with an insulated liner, sized 21.5 x 21 x 34 inches, built for feral colonies or multi cat households that need weatherproof housing outside.
HiCaptain builds this as a grey HDPE shell over an insulating layer, with an escape door so a cat can exit if cornered by another animal. It ships as an assembly kit rather than a ready to place structure, and at 12.5 kilograms it is meant to stay put once built rather than move around a yard.
- 21.5"D x 21"W x 34"H two story shelter
- Insulated liner inside HDPE shell
- Escape door for a second exit
- Grey finish, assembly required
Who it's for
Fits caretakers feeding and sheltering feral or community cats, or multi-cat homes that keep one or more cats outdoors. Less suited to anyone wanting a lightweight, no-assembly option.
Strengths and trade-offs
Drawn from this product's published specifications.
- Insulated liner for cold weather use
- Two story layout adds usable space
- Escape door for safety
- HDPE shell resists outdoor weather
- Assembly required out of the box
- Heavy at 12.5 kg, not easy to relocate
- No owner feedback yet on long-term durability
Performance notes
The insulating layer between the HDPE panels is what separates this from a plain plastic box, holding body heat in during cold spells. The elevated two story layout keeps the sleeping area off wet ground, and the escape door gives a cat a second way out if it needs to avoid a threat inside.
