A Feast for Crows
Margaery Tyrell gives Tommen three black kittens. Dorcas makes Tommen a mouse from scraps of fur and ties it on a fishing pole. The kittens love to chase it and Tommen likes nothing better than jerking it across the floor as the cats pounce on it. Ser Pounce catches a mouse but Lady Whiskers steals it from him. When Tommen tells this to his mother, Cersei Lannister, she replies, "Ser Pounce must learn to defend his right. In this world the weak are always the victims of the strong."
A Dance with Dragons
When King Tommen dines with his mother and Ser Kevan Lannister, he brings his kittens. At the dinner he claims Ser Pounce hissed at the bad cat that was at his window and scared him away. After dinner the king and his kittens are escorted to the royal bedchamber by Ser Boros Blount.
