Project Overview

This custom catio was thoughtfully designed to provide four beloved cats in Lowden, WA with a spacious, secure outdoor retreat they could access freely from their home. Measuring 10 feet wide by 8 feet deep and 8 feet tall, the freestanding structure was built to offer ample room for exploration while ensuring long-term durability against Washington’s ever-changing weather. The goal was to create a safe, enriching environment where the cats could experience the outdoors without compromising comfort or structural integrity.

Constructed with pressure-treated lumber, 1×1 black PVC-coated critter fencing, and topped with a classic ribbed steel metal roof, the catio was built to withstand moisture, wind, and seasonal elements. A short tunnel connects directly from the house wall through a cat door, allowing seamless access while keeping the main structure fully freestanding. Inside, shelves, ramps, and a cedar scratch post provide vertical enrichment, encouraging climbing, perching, and natural feline behaviors—all within a secure and thoughtfully crafted space.

Project Goals

  • Build a spacious 10′ x 8′ x 8′ freestanding catio large enough to comfortably accommodate four cats
  • Ensure the structure remains fully freestanding and not directly attached to the house
  • Install a short tunnel and wall cat door to allow safe, independent entry and exit
  • Create multiple vertical enrichment features, including shelves and ramps for climbing and perching
  • Incorporate a cedar scratch post to encourage natural scratching behavior
  • Use durable, weather-resistant materials capable of withstanding Washington’s climate
  • Provide enough interior space for the owners to comfortably spend time inside with their cats
  • Design a secure outdoor environment that allows the cats to safely experience fresh air and outdoor sights

Interior Features & Enrichment

This custom catio was designed to encourage movement, vertical exploration, and daily enrichment for four cats. The interior layout supports climbing, perching, scratching, and shared time with their owners, creating a balanced outdoor space that promotes both activity and relaxation.

Feature List

  • Climbing Shelves (Expanded Layout)
    Multiple shelves installed at varied heights throughout the 10’ x 8’ enclosure allow cats to leap, perch, and observe their surroundings. Additional shelves were incorporated to increase vertical pathways and maximize usable wall space for full-body movement and enrichment.
  • Ramps
    Slanted ramps connect shelf levels, creating smooth transitions between elevations and making vertical movement accessible and engaging for cats of all activity levels.
  • Cedar Scratch Post
    A built-in cedar scratch post encourages natural scratching behavior, supporting claw health while providing a dedicated outlet for instinctive activity within the enclosure.
  • Human Access Door
    A custom-built door allows owners to comfortably enter the catio, making it easy to spend time inside, interact with their cats, and maintain the space as needed.

Feature Purpose & Pet Personality Fit

This custom catio was thoughtfully designed around the unique personalities and energy levels of four beloved cats. With three young, energetic cats who love late-night zoomies, climbing high cabinets, and perching above the action—and one senior cat who prefers peaceful lounging—the layout balances high-energy vertical movement with comfortable resting zones. The result is a shared outdoor space that supports every stage of life and personality type.

  • The generous 10’ x 8’ x 8’ footprint provides ample room for bursts of energy, giving the three younger cats space to run, leap, and safely channel their nighttime zoomies.
  • Elevated shelves were intentionally installed at higher levels to mimic their natural habit of climbing cabinets and seeking high vantage points, satisfying their instinct to observe from above.
  • Integrated ramps create accessible vertical pathways, allowing energetic climbers to move fluidly between levels while also supporting safer navigation for the senior cat.
  • The cedar scratch post offers a dedicated outlet for scratching and stretching, supporting active play while protecting the structure.
  • Lower, open lounging areas within the enclosure provide the senior cat with a calm, comfortable space to relax outdoors without needing to climb.
  • The fully freestanding, spacious design ensures all four cats can share the enclosure comfortably—whether they’re sprinting, perching, or peacefully soaking in the fresh air.
