Jeff de Boer

Jeff de Boer is a Calgary-based Canadian artist and artifact maker whose work brings together sculpture, jewellery, armour, and historical imagination.

For more than 40 years, Jeff has explored the idea of armour made for cats and mice, creating meticulously crafted miniature suits that transform familiar historical forms into an imagined parallel world. What began in 1986 with his first armoured mouse has grown into an internationally recognized body of work encompassing thousands of unique pieces.

The best part of these is they can be customized with different metals, finishes, decorations and lace colours so each one is completely unique.

How Many Parts Does it Take to Make a Samurai Mouse?

A big part of my process is documenting my progress and key moments like this.

Crusader Mouse

When I produce a mouse like this my patrons have the option for a custom design in the ears as well as the shield.

Phoenix Cat

I enjoy a project that is about the fantasy as much as one that is about historical accuracy.

About Me

Jeff de Boer RCA ASA

National Geographic featured artist Jeff de Boer is a Calgary-based Canadian artist and artifact maker whose work brings together sculpture, jewellery, armour, and historical imagination.

For more than 40 years, Jeff has explored the idea of armour made for cats and mice, creating meticulously crafted miniature suits that transform familiar historical forms into an imagined parallel world. What began in 1986 with his first armoured mouse has grown into an internationally recognized body of work encompassing thousands of unique pieces.

Jeff’s work has been exhibited and collected internationally and has attracted a global following on social media, where he shares new projects and behind-the-scenes insights into his making process.

Working from his studio in Calgary, Jeff continues to create one-of-a-kind works, limited editions, and commissioned pieces by hand. His cat and mouse armour is available for purchase, and he welcomes inquiries about commissions, available works, and his ongoing exploration of the neoartifact—the idea of creating objects with an awareness that they may one day become artifacts of our own time.

Would you like to own one of my mice?

If you would like to own one of my suits of mouse armour, I sell my work directly from my studio in Calgary, Canada, on commission. Because my work is small and carefully packaged, I can ship it virtually anywhere in the world.

Why are my mice made in editions of 12?

Today, each new mouse design is produced as a limited edition of 12.

Creating a new mouse can involve as much as 100 hours of research, design, pattern development, tooling and preparation before I even begin making the edition. By producing a limited edition of 12, I can spread that initial investment across the edition and devote more time to the quality and craftsmanship of each individual mouse.

It allows me to make better work while offering collectors something that is genuinely limited.

How I Price a Mouse

My work is priced according to the time required to make it. My current studio rate is $100 CAD per hour, which covers my time and studio overhead.

A typical suit of mouse armour takes approximately 40–60 hours to complete. That puts the usual price of a mouse between $4,000–$6,000 CAD or approximately $3,000–$4,500 USD, depending on the exchange rate.

How a New Mouse Edition Begins

When I develop a new mouse, I usually begin by sharing the concept drawing on social media. Along with the drawing, I announce the price and open a reservation list for the edition.

There are 12 places only, and they are offered on a first-come, first-served basis.

Some designs include opportunities for limited customization—for example, a particular design in the ears or on the tip of the tail. When this is offered, I work directly with the collector to create that small original detail. I like doing this because although the edition shares the same fundamental design, these details allow each mouse to become unique and personal to its owner.

Can I Commission a Special Mouse?

Yes!

Some of the most interesting projects I have made have come from ideas suggested by collectors. If you have an idea for a mouse that is outside my regular editions, I am always interested in hearing about it.

If I decide that it is a project I would like to pursue, there are two possibilities.

Option 1 — A One-of-a-Kind Mouse

I can design and make a single mouse exclusively for you.

The challenge with a one-of-a-kind piece is that all of the research, design and tooling costs have to be carried by that one mouse. For a completely unique project, I would therefore expect a budget of approximately $8,000–$12,000 CAD or more, depending on the complexity of the design.

Option 2 — Create an Edition

The other possibility is that I design the mouse for you and then produce it as a limited edition of 12.

If you are comfortable with this approach, the cost can return to my standard edition pricing because the research, design and tooling costs are spread across the edition.

You get the opportunity to help inspire an entirely new mouse, while still receiving it at the normal edition price.

How to Reserve a Mouse

Submit the form on my Contact page! It has some required information that makes it easier for us to get started.

I use this information for my studio records and to prepare your invoice.

Once I receive your information, I will send you an invoice for a 50% deposit.

Your place in the edition is officially reserved once the deposit has been received.

Then the Fun Begins!

Once you are on the list, you don’t have to simply wait for your mouse to arrive. I document my work extensively on social media, sharing photographs, drawings and videos as I research, design and build the edition.

I hope you will enjoy following along and watching your mouse come to life.

When Your Mouse Is Finished

When I complete the edition, each mouse is professionally photographed in my studio.

I will email you a photograph of your completed mouse along with the final invoice for the remaining balance and shipping. Shipping is usually under $200 CAD, depending on the destination.

Once the final payment has been received, I will contact you one final time to confirm your shipping address.

Then I carefully package your mouse and send it on its journey to you.

And that is when your piece of my little history becomes part of yours.

Would you like to commission a Suit of Cat Armour?

One-of-a-Kind Works

Every suit of cat armour I create is a completely unique work of art. These are not editions or reproductions. Each piece is designed and built specifically as an individual portrait, memorial, or reliquary celebrating a particular cat.

A full cat armour commission typically requires 150–800 hours of design and fabrication.

In the past, I have also created smaller-scale works such as cat helmets, which can be a more accessible option when a full suit is beyond budget. These helmet works typically require 75–400 hours depending on complexity and detail.

Pricing

Same rate as my mouse armour: $100 CAD per hour

Full armour typical investment: $15,000–$80,000 CAD

Cat helmet typical investment: $7,500–$40,000 CAD

The final price is determined by the concept, materials, complexity and hours required. I can also design to a set budget that you have in mind.

Commissioning

The process begins with a conversation about your cat and the story you want the work to tell. Photographs and information about your cat are used to develop the design.

Once the concept is established, I provide a price estimate and timeline. Upon approval, a 50% deposit secures the commission and work begins.

Once I begin fabrication, collectors are invited to follow the progress of the work through regular updates posted on my social media, offering a behind-the-scenes view of the development of the piece as it comes to life.

Once the work is complete, I will provide high-quality photographs of the finished piece along with a final invoice for the remaining balance, as well as shipping costs. Shipping typically ranges from $200–$500 CAD depending on destination, and I am able to ship worldwide. Once the final payment is received, the work is carefully packaged and shipped.

Because each piece is entirely unique, commissions are accepted selectively and production times vary.

As these works are rare and significant, I may also, in the future, reach out to collectors to inquire about the possibility of temporarily loaning the work for exhibition purposes.

These are not simply objects made about cats. They are one-of-a-kind artifacts made to preserve the memory of one particular cat.
