Interior Features & Enrichment
This catio was built with enrichment in mind, offering a dynamic and stimulating environment that encourages climbing, lounging, and observing—all while staying safe from outdoor predators.
Feature List
Climbing Shelves Multiple cedar shelves installed at staggered heights allow the cats to leap, climb, and explore vertically—an essential outlet for young, energetic cats.
Ramps Angled cedar ramps provide continuous movement across levels, connecting platforms and adding variety to the navigation paths inside the structure.
Perches Elevated lounging spots positioned for both sunbathing and shaded rest—ideal for midday relaxation with panoramic views.
Cat Cubbies (x2) Cozy hideaways built into the corners of the catio for privacy, naps, and a sense of safety—perfect for retreating after high-energy play.
Cat Domes (x2) Clear bubble-style observation windows offer the cats a 180° view of their surroundings while also adding a playful, interactive design element.
Tunnel Enclosure Fully enclosed and roofed tunnel gives the cats long-distance roaming ability while moving through the backyard safely and securely.
Garden Viewing Area A spacious end-of-tunnel platform positioned to overlook the backyard garden—ideal for birdwatching and nature-watching.
Feature Purpose & Pet Personality Fit
With both cats being just one year old, this build focused on height, motion, and sensory stimulation. These features were chosen to match their energetic, curious nature:
We installed tiered climbing shelves and ramps to keep these adventurous one-year-olds constantly engaged and moving.
The tunnel and viewing zone offer long-distance travel and exploration while keeping them secure from coyotes and other wildlife.
Cubbies and domes were added to offer quiet hideouts and visual stimulation—important for building confidence in young, curious cats.
The domes and garden-facing perch encourage natural behaviors like birdwatching, while blending into the landscape.
