Irish Spring- And I Like It Too! Pt. 2 August 29, 2007 urngarden.com Our summer experiment with Irish Spring as a non-toxic cat repellent has been somewhat successful. Probably more so, had I been shredding and spreading bar soap on a regular basis. For the Colgate Palmolive R & D people, please develop a shredded blend of the Original Scent bar soap in colors to match popular styles of garden mulch. That is all. Thank you for your consideration.
