Canadian artist Jeff de Boer agreed that the animals may well be gladiators and medieval knights,so they must have their costumes for the defense.So,he created a miniature armor for mice and impressive - for cats.On average, every costume he spent from 10 to 100 hours.Jeff used a silver, wood and bronze for its work,which cost up to $ 2000 per unit.Fun fact: the artist tried to put a cat in one of his costumes, but failed because the animal scratched him.
