Entertainment Weekly

King Tommen’s beloved cat, who was introduced in Season 4, was never seen again after his owner's death. What happened? “Cersei hated the name ‘Ser Pounce’ so much she could not allow him to survive,” co-creator David Benioff tells EW. “So she came up with her most diabolical (execution). Ser Pounce’s death was so horrible we couldn’t even put it on the air.”
