Linvivon Cat Door for Window – Adjustable 31"-36" Width, 4 Locking Modes, Magnetic Closure, Weatherproof Aluminum Frame

Freedom for your cat, control for you

Linvivon’s Cat Door for Window is built to balance pet curiosity with household practicality. The design pairs a strong aluminum frame with a clear, HD glass panel, offering pets a seamless doorway to the outdoors while you maintain weather resistance and airflow control. The setup is intuitive, aimed at pet owners who want a no-hassle solution that doesn’t require permanent alterations to their home.

Adjustable fit for most sliding windows

The window insert supports a width range from 31" to 36", making it suitable for many standard sliding window tracks. Before purchasing, take a moment to measure your track width and thickness to ensure a precise fit. A magnetic closure at the bottom helps the panel return to its resting position after every use, keeping the doorway looking neat and consistent even with frequent activity.

• Non-destructive, tool-free installation that won’t harm window frames
• Magnetic bottom keeps the panel aligned and minimizes rattling in windy conditions
• Weatherproof by design, shielding your interior from drafts and pests

Four locking modes for flexible access

Switch easily among four independent modes to tailor pet access to your routine: out only, in only, both in and out, or fully locked. This versatility is helpful when you’re away, during bad weather, or simply when you want to limit indoor-outdoor traffic.

• Increased control over when your cat can explore outside
• Simple mode changes to adapt to changing schedules
• Clear visibility through the door for your pet’s daily routines

Designed for all-season use

Crafted from heavy-duty aluminum alloy and a robust HD glass panel, this cat door stands up to rain, wind, snow, and sun. The materials also help keep dirt and insects from entering, while still allowing your cat to observe the outdoors with ease.

Real-life use and benefits

Whether your cat loves sunlit windowsills, backyard exploration, or simply wants the option to come and go, this window insert provides a practical gateway. The design emphasizes ease of use, reliable closure, and durable performance, turning the window into a functional pet door rather than a temporary workaround. It’s a possible solution for households balancing pet freedom with home environment control, without promising performance in all situations.
