Adjustable Window Cat Door – Aluminum Frame Pet Door for Vertical Sash Windows 23.6"–37.4" Wide, Weatherproof, Easy Install, Modern Honeycomb Design (Fits 23.5"-37.5" W Windows)

Let your cat explore freely — without sacrificing your home’s style or comfort. Introducing the JubiTail Premium Vertical Window Cat Door, a thoughtfully engineered solution for pet lovers who appreciate aesthetics as much as functionality. Designed for vertical sash windows between 23.6" to 37.4" wide, this cat door features a durable all-aluminum frame with a modern honeycomb sliding panel — a combination of strength, elegance, and smart space efficiency. Unlike traditional plastic window inserts, the JubiTail door offers minimal visual obstruction while maintaining top-tier insulation performance. Installation is a breeze — no tools, drilling, or DIY headaches. Just measure, adjust, and seal. The included EPDM and silicone weatherstrips ensure tight sealing, while the magnetic flap gently snaps back into place after each use. We’ve even added thoughtful extras: a removable window lock for added peace of mind, and a reusable kraft carry bag that doubles as a cozy play hut for your cat. Whether you’re in a sunny loft or a cozy condo, this window cat door adapts beautifully to your lifestyle.
