Fran Moore, the longtime director and co-founder of the nonprofit Orange County Animal Rescue Coalition (OCARC), has died, according to the group which posted news of her death on Facebook.

Moore co-founded the OCARC in 2001 with Marty Suesberry, Lorretta Laslo and Bonnie Arita. The two volunteered for more than 12 years at the Irvine Animal Care Center before starting the nonprofit. The organization rescues kittens and cats from animal shelters, socializing them and nursing them to good health. The cats then pass to new owners through local adoption events.

In a 2005 interview, Moore said she hoped that OCARC would one day go out of business, hopeful that someday there would be no kittens needing rescue or cats facing euthanasia in overcrowded shelters. Of course, she said she knew that dream would never come true and the task of rescuing cats and uniting them with happy families would forever be needed.

With Fran at the helm, OCARC has saved over 3,800 cats’ lives to date.
