The 6 May 1916 Motion Picture News noted that filming had already begun on The Velvet Paw, and a week later the 13 May 1916 Moving Picture World mentioned that filming was being done on location in Washington, D.C.
       According to a belated item in the 17 June 1916 Motion Picture News Gail Kane and House Peters were in Washington, D.C., with director Maurice Tourneur, shooting more than 300 scenes "among the federal buildings." Three months later, the 9 September 1916 issue of the same magazine elaborated: "Tourneur of the Paragon Studio took a company of thirty players to Washington, where they remained for three weeks taking pictures in and around the Capitol. Then an exact replica of the Senate chamber was reproduced at the Paragon Studio, where characters most resembling the leading lights of our national political center were chosen, giving not only the Senate atmosphere, but also characters representing all the prominent politicians at the Capitol [see item below]. The gallery, built to hold 300 persons, and the main chamber required more than half the entire floor space of the spacious Paragon Studio. The sets had to be built so solid that an infuriated mob of spectators would set upon a maddened ex-Senator and throw hm over the railing into the assembled body which has just voted for the Child Labor Bill." Variety mentioned that as the film ended with the lovers embracing, an inter-title card quoted a verse from "The Star Spangled Banner."
       Another item in the 9 September 1916 Motion Picture News identified several Congressmen represented in the film by lookalikes. They were Speaker of the House James "Champ" Clark of Missouri, Cyrus Sulloway of New Hampshire, James Mann of Illinois, A Jeff McLemore of Texas, and Joseph W. Fordney of Michigan, "who figured prominently in the child labor legislation which recently took up the attention of the national legislators."
       The 27 May 1916 Motion Picture News mistakenly named Alice Brady as the star of The Velvet Paw.
       The original release date was set for 9 October 1916, according to the 19 August 1916 Moving Picture World.
       The original title of the film was Mary, M.C.
       According to modern sources, Ben Carré was the art director of this film.
       The 25 March 1916 Moving Picture World credited director Maurice Tourneur as “vice president and general director” of Paragon Films, Inc., of Fort Lee, NJ, a subsidiary of World Film Corp.
       The National Film Preservation Board (NFPB) included this film on its list of Lost U.S. Silent Feature Films as of January 2021.
