As a child, Jeff De Boer, the son of a sheet metÂal fabÂriÂcaÂtor, was fasÂciÂnatÂed by the EuroÂpean plate armor colÂlecÂtion in Calgary’s GlenÂbow MuseÂum:
There was someÂthing magÂiÂcal or mysÂtiÂcal about that empÂty form, that conÂtained someÂthing. So what would it conÂtain? A hero? Do we all conÂtain that in ourÂselves?
After gradÂuÂatÂing from high school wearÂing a parÂtial suit of armor he conÂstructÂed for the occaÂsion, De Boer comÂpletÂed sevÂen full suits, while majorÂing in jewÂelÂry design at the AlberÂta ColÂlege of Art and Design.
A sculpÂture class assignÂment proÂvidÂed him with an excuse to make a suit of armor for a cat. The artist had found his niche.
Using steel, silÂver, brass, bronze, nickÂel, copÂper, leather, fiber, wood, and his delÂiÂcate jewÂelÂry makÂing tools, DeBoer became the cats’ armorÂer, spendÂing anyÂwhere from 50 to 200 hours proÂducÂing each increasÂingÂly intriÂcate suit of feline armor. A noble purÂsuit, but one that inadÂverÂtentÂly creÂatÂed an “imbalÂance in the uniÂverse”:
The only way to fix it was to do the same for the mouse.


“The suit of armor is a transÂforÂmaÂtion vehiÂcle. It’s someÂthing that only the hero would wear,” De Boer notes.
Fans of David Petersen’s Mouse Guard series will need no conÂvincÂing, though no real mouse has had the misÂforÂtune to find its way inside one of his astonÂishÂing, cusÂtom-made creÂations.
Not even a taxiÂdermy specÂiÂmen, he revealed on the MakÂing, Our Way podÂcast:
It’s not an altoÂgethÂer bad idea. The only reaÂson I don’t do it is that holÂlow suit of armor like you might see in a museÂum, your imagÂiÂnaÂtion will make it do a milÂlion things more than if you stick a mouse in it will ever do. I have put armor on cats. I can tell you, it’s nothÂing like what you think it’s going to be. It’s not a very good expeÂriÂence for the cat. It does not fulÂfill any fanÂtasies about a cat wearÂing a suit of armor.
Though cats were his entry point, De Boer’s symÂpaÂthies seem aligned with the underÂdog — er, mice. EquipÂping humÂble, hypoÂthetÂiÂcal creaÂtures with exquisÂiteÂly wrought, hisÂtorÂiÂcal proÂtecÂtive gear is a way of pushÂing back against being perÂceived difÂferÂentÂly than one wishÂes to be.
AcceptÂing an HonÂorary MFA from his alma mater earÂliÂer this year, he described an armored mouse as a metaphor for his “ongoÂing cat and mouse relaÂtionÂship with the world of fine art…a misÂchieÂvous, rebelÂlious being who dares to comÂpete on his own terms in a world ruled by the cool cats.”
Each tiny piece is preÂcedÂed by painstakÂing research and many refÂerÂence drawÂings, and may incorÂpoÂrate speÂcial mateÂriÂals like the JapanÂese silk haori-himo cord lacÂing the shoulÂder plates to the body armor of a SamuÂrai mouse famÂiÂly.
AddiÂtionÂal creÂations have refÂerÂenced MonÂgoÂlian, gladÂiÂaÂtor, cruÂsadÂer, and SaraÂcen styles — this last perÂfect for a PerÂsian cat.



“I mean, “Why not?” he asks in his TED‑x Talk,Village Idiots & InnoÂvaÂtion, below.
His latÂest work comÂbines eleÂments of Maratha and HusÂsar armor in a verÂiÂtaÂble puzÂzle of minusÂcule pieces.
