The sunlight speaks, and its voice is a bird:
It glimmers half-guessed, half-seen, half-heard,
Above the flowerbed, over the lawn--
A flashing dip, and it is gone,
And all it lends to the eye is this--
A sunbeam giving the air a kiss.
When shelters/feral rescue groups trap feral cats and spay and neuter they often clip one ear tip so at a distance they're able to see whether cats have already been spayed or neutered or not. This is a feral cat with it's left ear clipped.
