author
Best known for a charming mid-19th-century collection of cat stories, this elusive writer published as “an old tabby” and turned feline adventures into gentle moral tales for young readers.

by Tabitha Grimalkin
Very little appears to be known for certain about the person behind the name Tabitha Grimalkin. The most reliable evidence available here points to Tabitha Grimalkin as a pseudonym connected with Tales from Catland, for Little Kittens, a children's book published in 1852.
That book imagines a playful world of talking cats and fairy-tale adventures, written in a warm, storybook style for children. Modern library and public-domain records consistently associate the name with this work, and Project Gutenberg currently lists it as the only title under that author name.
Because the real identity behind the pseudonym is not clearly confirmed in the sources I found, it is best to think of Tabitha Grimalkin as the pen name attached to a small but memorable feline classic rather than as a fully documented biographical figure.
