This little duologue, by 'A. L. Little' appears in the 9th May 1913 edition of newspaper of the Women's Freedom League, the Vote.
"Uncle McKenna" is supposed to be the the Liberal MP Reginald McKenna, who was the Home Secretary from 1911-1915. The duologue refers to the Prisoners (Temporary Discharge for Ill Health) Act of 1913, a piece of hotly contested legislation popularly known as the "Cat and Mouse Act" which allowed suffragette hunger-strikers to be forcibly fed to the point of near death, then released on license to recuperate and imprisoned again to continue their sentence as soon as they were well enough... and when they were back in prison they went on hunger-strike and were forcibly fed to the point of near death at which point they were released on license to recuperate and imprisoned again to continue their sentence as soon as they were well enough... [repeat]
You can read about it online here and the debates in the House of Commons are available to read on Hansard.
Interesting that the "cat" in this duologue is female rather than male... does that make it seem more or less cruel?
