The Feliner is an ancient ship that was found outside Soul Sever's lair and rebuilt by the ThunderCats so they could travel to Avista. Panthro initially tried to fly it, but that was when he found out that he had acrophobia (the fear of heights). Then all of a sudden, Tygra flew it like it was nothing and said it felt natural. At that point, Lion-O said, "No wonder your ancestors were pilots." This was a reference to Tygus and Javal.
