Measure before buying
Catio Fit & No-Drill Planner
Choose a window, balcony, or yard path from the space you actually have. Get a renter-aware permission gate, a measured envelope, escape and weather checks, and one printable shopping plan.
Important: this tool organizes measurements and questions. It is not a structural or escape-proof guarantee. Check the lease, landlord or HOA, local code, product instructions, weather loads, and every attachment point before a cat enters the space.
About 60 seconds
Build the physical-fit plan first
Use clear opening measurements for a window, and usable floor measurements for a balcony or yard. The result deliberately avoids pretending that an unverified product will fit.
Your fit path
Window insert / box
Compare these measurements with the product's listed exterior dimensions and required clearances. Do not infer fit from a marketing photo.

Materials and product checklist
Supervision plan
- Inspect edges, roof, floor, latches, fasteners, tunnel joints, and gaps before every early session.
- Introduce the space gradually and supervise every session until you know how the cat uses it.
- Provide shade, fresh water, and an immediate way back indoors.

Fast answer
Which catio path usually fits?
- Renter + window + no drilling: start with a landlord-approved window insert/box or a fully freestanding enclosure. An insect screen alone is not containment.
- Balcony: treat height, wind, rail gaps, overhead escape, falling objects, and building rules as hard gates. Prefer a fully enclosed purpose-built system, not improvised netting.
- Yard or patio: a freestanding kit avoids attaching the structure to the house, but still needs a secure roof, floor/ground perimeter, latches, weather plan, and predator assessment.
Before any purchase
Five checks the product page cannot do for you
1. Permission gate
Get landlord, management, HOA, and permit answers in writing when applicable. “No drill” does not automatically mean lease-safe.
2. Measure twice
Record the clear opening, usable footprint, path to the installation area, door swing, roof clearance, and room for assembly.
3. Escape-point check
Inspect the roof, floor, mesh, corners, tunnel joints, access door, latches, and every gap. Ordinary insect screen is not designed for cat containment.
4. Weather check
Plan for shade, ventilation, rain, snow load where applicable, standing water, wind, hot surfaces, and a fast route indoors.
5. Supervision plan
Introduce the cat slowly, watch how the cat climbs and pushes surfaces, and recheck hardware. Humane World recommends supervision while cats use a catio.
