Spoon ear or Loffohr rabbits are due to a recent mutation that makes the ear rounder and more open toward the middle and bottom portions of the ear, so they are somewhat spoon-shaped. It gives the rabbits a mouse-ear appearance.

The genetic mechanisms for spoon ear are still not fully understood, but it appears to be recessive., meaning both parents must have at least one copy of the spoon ear allele to produce spoon ear offspring.
