The stars fired off a fax to the editor-at-large Thursday, imploring him to change his fashion taste, the New York Post reported Friday.
Leon has been quoted as saying "The Golden Girls" is one of his favorite TV shows.
"I was delighted to hear that you are a fan of 'The Golden Girls,'" McClanahan wrote Talley. "As you may know, Bea Arthur, Betty White, and I are all very involved with animal causes ... I saw photos of you in fur at the fashion shows this week. Would you consider donating your furs? I would be honored to meet with you to accept them. PETA takes coats donated by people who have had a change of heart about wearing fur."
A Vogue spokesman confirmed to the Post "Andre is, indeed, a big fan of Rue McClanahan and 'The Golden Girls.'"
However, the spokesman added, "Other than that, he has no comment."
