Lat take a cat

Lat take a cat, and fostre him wel with milk,
And tendre flesh, and make his couche of silk,
And lat him seen a mous go by the wal;
Anon he weyveth milk, and flesh, and al,
And every deyntee that is in that hous,
Swich appetyt hath he to ete a mous.

from Chaucer’s “Canterbury Tales” (c. 1388)
