Mice are always on the hunt for food or a cozy place to nest. The Box-Kat’s durable plastic construction is neither edible nor easily chewable, deterring mice and other small rodents from trying to break through. When mice encounter the Box-Kat, they instinctively search for openings, a way over, or a path underneath. Finding none, they quickly move on in search of easier targets.

During testing, we placed 50 mice inside a Box-Kat enclosure. Not only did they fail to chew through the panels, but after 90 minutes, 80 percent of the mice gave up, piled into a corner, and went to sleep. The Box-Kat is proven to be a simple, humane solution to mice intrusion.

The Box-Kat stands two inches taller than the highest jump of a house mouse, making it impossible for them to leap over. Its flexible design ensures a snug fit to the ground, leaving little to no gaps for mice to crawl underneath.

Box-Kat is specifically designed to thwart house mice — the most frequent cause of vehicle rodent damage— and is extremely effective. Its height and panel texture are engineered to stop them from leaping over, burrowing under, climbing up, or chewing through.

It may also deter larger rodents such as rats or squirrels, but effectiveness can vary depending on their size and behavior.

For best results, make sure your setup is as level as possible and panels are securely clipped together.

The Box-Kat is designed for effortless assembly. Each of the white panels and black connectors connects seamlessly using push-in fender clips to ensure a secure, rodent-proof seal.

Yes — that’s exactly what it’s designed for.

Thanks to our patented flex-panel technology, Box-Kat 2.0 can mold to the shape of your driveway, garage, or parking pad — including areas with cracks, dips, gravel, or slight slopes.

The panels flex and settle naturally into surface contours, forming a continuous barrier that keeps rodents out, even when the ground isn’t perfectly flat.

Just make sure to clear any tall grass or large debris, and anchor as needed for outdoor setups.

Yes! Box-Kat is built for indoor or outdoor use — but the elements can be a factor.

To keep your barrier securely in place, we recommend using an anchoring system such as:

• Water jugs, sandbags, or cinder blocks for hard surfaces
• Garden stakes for soil or grass setups

Make sure the ground is as flat as possible and clear of tall grass or debris. Proper prep = better performance.

(See our Assembly Instructions for a full setup guide.)

The Box-Kat is crafted from high-quality, durable plastic materials, ensuring reliable performance and long-lasting protection. However, like any product, it may experience normal wear and tear over time. Exposure to extreme temperature fluctuations, UV rays, moisture, and wind can gradually impact its condition. Regular care and proper setup will help maximize its lifespan and effectiveness.

With proper care and limited exposure to extreme heat or UV, the Box-Kat is designed to last between 5 to 10 years. For added assurance, we offer a materials warranty of five years for indoor use and two years for outdoor use.

While the Box-Kat delivers highly effective mouse protection, its performance relies on proper setup and routine maintenance. External factors such as wind, pets, or children can disturb the barrier, so occasional inspections are recommended to ensure it remains secure. If wind gusts reach 40mph, extra precautions anchoring the Box-Kat — including taking it down — may be necessary. A flying Box-Kat may not be useful again and can damage vehicles.

With a little vigilance, the Box-Kat offers reliable, long-lasting protection for your vehicle and property.
