Important: this worksheet records measurements and questions. It is not a structural, installation, 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.

Catio fit measurements

Project / date:

1. Location and permission

Written permission or rule reference HOA / management / local-code check Emergency egress or door-swing constraint

2. Clear opening

Measure the usable opening—not the outside of the trim. For a non-window route, record the door, panel, or tunnel opening the cat must use.

Clear width in Clear height in Sill / threshold depth in Exterior clearance in Insert / panel thickness in Narrowest access point in

Window / door type and locking method Weather seal and complete transition to enclosure

3. Usable footprint and assembly path

Usable width in Usable depth in Usable height in Roof clearance in Assembly-path width in Door-swing clearance in

Direct window / door access Tunnel / connector needed Separate supervised transfer Quick indoor return stays clear

5. Product-dimension comparison

Do not infer fit or safety from a product photo. Copy the exact documented dimensions and instructions for each option.

Candidate / model	Exterior dimensions	Required clearance	Attachment / base	Weather limits	Pass / pause

Assembly path, return dimensions, or missing documentation Final reason to pass or pause

Pause before purchase if any gate is unresolved

Permission, structural attachment, elevated wind or fall exposure, emergency egress, weather limits, escape points, and undocumented dimensions are not guesswork items. Use the exact product instructions and building-specific advice where needed.
