Japanese Maple Cat Pin/Pendant3. 25"H x 2. 25"W x . 5"D Pin or Pendant made out of Sterling, Brass and Copper. These metals are not coated and will develop a lovely patina over time, and will last forever. Japanese maples are monoecious meaning they have both male and female flowers on the same plant. These flowers are inconspicuous and small, and though they do not attract insects, grouse, quail, and many songbirds adore them which is perhaps why this kitty loves them so much.
