How Does It Work?
How Does It Work?
Unlike traps or poisons that only deal with rodents after damage is done, Box-Kat works as a physical barrier to keep them out completely.
Its patented flex panels mold to uneven ground and prevent burrowing. Standing 14 inches tall, the Box-Kat is designed to stop mice from jumping or climbing over — providing 360° protection from the most common vehicle-invading rodents.
No chemicals. No cleanup. Just peace of mind.
Is It Effective on All Rodents?
Is It Effective on All Rodents?
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.
Can I Use the Box-Kat Outside?
Can I Use the Box-Kat Outside?
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.)
Will It Work on Uneven or Cracked Surfaces?
Will It Work on Uneven or Cracked Surfaces?
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.
FREQUENTLY ASKED QUESTIONS
When will my Box-Kat 2.0 ship?
All preorders will ship by the end of September 2025 — just in time for fall and winter rodent season.
Do I have to pay in full today?
Nope! You’ll just pay a $50 deposit now to reserve your kit. The remaining balance will be charged on September 15. Cancel anytime before fulfillment for a full refund.
What if I change my mind?
You can cancel your preorder at any time before it ships and receive a full refund — no questions asked.

Each Box-Kat is constructed of 5-foot white panels attached by flexible black connectors. These can absolutely be manipulated and shaped to best suit your vehicle and storage situation.
Can I drive over the Box-Kat?
No. For repeated daily use we have supplied a pair of screws and wing nuts for ease of access.
Check out our Instructions Page for more information.
How long will my Box-Kat last?
The Box-Kat is crafted from high-quality 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 season after season.
Is there a warranty on the Box-Kat?
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.
