Twenty thousand copies of the book were released in September 1907 and another 12,500 the following December. Potter composed a few miniature letters for child friends as if from the characters in the tale, and, in 1917, she released a painting book under Tom Kitten's name. In 1935, two books of piano pieces and piano duets for children were published with one piece inspired by Tom Kitten and another by the Puddle-Ducks. Tom and other characters in the book have become the subjects of a variety of merchandise over the years including porcelain figurines and plush toys. The tale is still in print, and has been translated and published in several languages.
