Wompat
From Memory Alpha, the free Star Trek reference
Wompats are an animal native to Cardassia Prime that are often kept as pets.
Jil Orra, Gul Madred's daughter, kept a pet wompat. She would take it with her when she went to visit her father at work. (TNG: "Chain of Command, Part II")
This unnamed wompat was portrayed by a Ferret.
