i think its a ferret

They may have used a ferret as the animal actor, but it was called a wompat in the episodes:

MADRED: "I want you to be very careful with your wompat from now on, Jil Orra. Now that she's separated from her mother, she depends on you."

Hope that helps. --GO RED SOX 06:13, 23 October 2007 (UTC)
