Use Toys to Guide

Use a cat teaser or laser pointer to guide your cat through the open flap.

Lure with Treats

If toys don't work, place their favorite treats or wet food on the other side.

Practice Pushing

Reward Success

Give praise and rewards immediately after they pass through to build a positive habit.

  • Will this fit my horizontal sliding window?

    No, this unit is designed ONLY for vertical sash windows (windows that slide up and down). It relies on the downward pressure of the window sash to hold it in place. It will not work on horizontal sliding windows or casement windows.

  • Do I need to drill holes to install this? Is it renter-friendly?

    No drilling or tools are required! It features a tension-knob locking system that secures the unit into the track. It is 100% renter-friendly and can be easily removed without leaving any damage or marks on your window frame.

  • Is it weatherproof? Will my room get cold in winter?

    Yes, superior insulation. Unlike basic plastic, our double-layer honeycomb fabric traps air to block heat. Includes weather stripping and gap seals for a tight, draft-free fit.

  • What size pets can use this door?

    The flap opening is 7" W x 7.5" H. It is ideal for cats and small dogs weighing up to 18 lbs (8 kg). We highly recommend measuring your pet's chest width (should be under 6.9") before purchasing to ensure comfortable access.

  • Can I lock the door to keep my cat inside?

    Yes, the flap features a 4-way locking system. You can set it to: In Only, Out Only, Fully Open, or Fully Locked. This allows you to keep your pet safely indoors at night or prevent stray animals from entering your home.

  • No-Drill Window Access: Give your cat independent indoor and outdoor access without cutting a door or permanently modifying your home. The removable design is suitable for apartments, rentals, patios, and seasonal use.
  • Clear-View Aluminum Design: A sturdy aluminum frame surrounds a wide transparent center panel that helps preserve natural light and your outdoor view. Honeycomb side panels adjust to the window width while maintaining a clean, finished appearance.
  • 4-Way Control and Weather Sealing: Set the flap to in only, out only, fully open, or locked. The magnetic flap returns toward the closed position, while the included seal strips help reduce small gaps, drafts, dust, rain splash, and insects.
  • Measure Before Ordering: Designed only for vertical sash windows measuring 23.5-37.5 inches wide with track depth under 0.9 inch. The flap opening measures 7 x 7.5 inches and is recommended for cats up to 18 lb.
  • Secure and Removable Installation: Place the insert in the window track, adjust the width, and tighten the locking knobs. The included window lock helps limit window movement. Not compatible with horizontal sliding, casement, or crank windows.
