The domain name nicemice.net is derived from a poem (shown below) by J.R.R. Tolkien. It is poem 12 of The Adventures of Tom Bombadil, which was published on its own in 1962 and later as part of the compilations The Tolkien Reader and Poems and Stories.

 
       CAT
 
The fat cat on the mat
    may seem to dream
of nice mice that suffice
    for him, or cream;
but he free, maybe,
    walks in thought
unbowed, proud, where loud
    roared and fought
his kin, lean and slim,
    or deep in den
in the East feasted on beasts
    and tender men.
The giant lion with iron
    claw in paw,
and huge ruthless tooth
    in gory jaw;
the pard dark-starred,
    fleet upon feet,
that oft soft from aloft
    leaps on his meat
where woods loom in gloom—
    far now they be,
    fierce and free,
    and tamed is he;
but fat cat on the mat
    kept as a pet,
    he does not forget.
