Did Lee Meriwether reprise her role?
She isn't credited, I noticed that both Lee's and Eartha's Catwomen are voiced by the same person in "Return of the caped Crusaders"...
So... who did it? Was it Julie Newmar?
The other two Catwomen (Catwomans?) are uncredited. Maybe I can find out something at the Toon Zone forums.

Casting director Wes Gleason answered your question on Twitter. Both the Lee Meriwether Catwoman and the Eeartha Kitt Catwoman were voiced by Sirena Irwin.
