a portrait - actually two

Victoria and Albert Museum Department of Prints and Drawings and Department of Paintings Accessions 1954 London: HMSO, 1963 . PD.  Thanks to the V&A.

The text of the collection entry online at the Victoria and Albert Museum says,
"SHARPE, Charles Kirkpatrick (1781-1851)
...
Portrait taken on the pier at Leith. [A little girl, full-length, full face, standing with a kitten at her feet]
Signed C Sharpe. Inscribed in ink with title.
Wash. E.1634-1954"

 To me, that's two portraits:  yes,a little girl, but also her kitten must be granted its presence and due.   Both of them are as round as dumplings; the kitten must be one of those straight-up British Shorthairs with a round cobby head and body.
