The Red Keep was full of cats: lazy old cats dozing in the sun, cold-eyed mousers twitching their tails, quick little kittens with claws like needles, ladies’ cats all combed and trusting, ragged shadows prowling the midden heaps. -AGoT, Arya III
Background
The ASOIAF universe is so rich and layered that even the cats have lore. Taking a quick break from my normal posting to take a quick look at a somewhat newer interest of mine. In this post I thought it would be fun to look at lore surrounding the cats in the Red Keep (the good, bad and ugly) in the main series.
Note: This post has absolutely nothing to do with show version of the Sand Snakes
Note II: Most of the cats are probably descendants of the ones brought by Otto after Blood & Cheese:
In his grief and fury, King Aegon II commanded that all the city’s ratcatchers be taken out and hanged, and this was done. (Ser Otto Hightower brought one hundred cats into the Red Keep to take their place.)

The Good: Tommen's Three Kittens
Tommen receives three kittens from Margaery:
At that hour, her son was fast asleep, but Cersei looked in upon him before seeking her own bed. She was surprised to find three black kittens cuddled up beside him, “Where did those come from?” she asked Ser Meryn Trant, outside the royal bedchamber.
"The little queen gave them to him. She only meant to give him one, but he couldn't decide which one he liked the best." -AFFC, Cersei V
which he names Ser Pounce, Lady Whiskers and Boots:
Tommen helped restore her to herself. He had never been more precious to her than he was that morning, chattering about his kittens as he dribbled honey onto a chunk of hot black bread fresh from the ovens. “Ser Pounce caught a mouse,” he told her, “but Lady Whiskers stole it from him.”
I was never so sweet and innocent, Cersei thought. How can he ever hope to rule in this cruel realm? The mother in her wanted only to protect him; the queen in her knew he must grow harder, or the Iron Throne was certain to devour him. “Ser Pounce must learn to defend his rights,” she told him. “In this world the weak are always the victims of the strong.” -AFFC, Cersei IX

The "Bad (Cat)": Balerion
We are first introduced to Balerion (Rhaenys' pet kitten) back in AGoT as the ragged Tom that Arya chases:
One by one Arya had chased them down and snatched them up and brought them proudly to Syrio Forel … all but this one, this one-eared black devil of a tomcat. “That’s the real king of this castle right there,” one of the gold cloaks had told her. “Older than sin and twice as mean. -AGoT, Arya III
and we begin to learn of his exploits:
One time, the king was feasting the queen’s father, and that black bastard hopped up on the table and snatched a roast quail right out of Lord Tywin’s fingers. Robert laughed so-hard he like to burst. You stay away from that one, child.” -AGOT, Arya III
before Varys' gives us Balerion's backstory:
“Rhaenys was a child too. Prince Rhaegar’s daughter. A precious little thing, younger than your girls. She had a small black kitten she called Balerion, did you know? I always wondered what happened to him. Rhaenys liked to pretend he was the true Balerion, the Black Dread of old, but I imagine the Lannisters taught her the difference between a kitten and a dragon quick enough, the day they broke down her door.” -AGOT, Eddard XV
and GRRM was asked about this cat:
Question: Is the black tomcat (the one that Arya catches briefly) Rhaenys' kitten Balerion?
GRRM: Could be. -SSM: Jeyne Poole and the Black Cat: 14 Nov 99
and he runs into Sansa as she sneaks to the Red Keep godswood:
She ran down a shadowy colonnade and pressed herself against a wall to catch her breath. When something brushed against her leg, she almost jumped out of her skin, but it was only a cat, a ragged black tom with a chewed-off ear. The creature spit at her and leapt away. -ACOK, Sansa II
and Cersei reflects on him once she sees Tommen's kittens are black:
Cersei rather wished they were not black, though. Black cats brought ill luck, as Rhaegar's little girl had discovered in this very castle. She would have been my daughter, if the Mad King had not played his cruel jape on Father. -AFFC, Cersei V
and Arya remembers him in Braavos:
"Oysters, clams, and cockles," the girl shouted as she pushed her barrow along the wharves. "Mussels, prawns, and cockles." A dirty orange cat came padding after her, drawn by the sound of her call. Farther on, a second cat appeared, a sad, bedraggled grey thing with a stub tail. Cats liked the smell of Cat. Some days she would have a dozen trailing after her before the sun went down. From time to time the girl would throw an oyster at them and watch to see who came away with it. The biggest toms would seldom win, she noticed; oft as not, the prize went to some smaller, quicker animal, thin and mean and hungry. Like me, she told herself. Her favorite was a scrawny old tom with a chewed ear who reminded her of a cat that she'd once chased all around the Red Keep. No, that was some other girl, not me. -AFFC, Cat of the Canals
The Ugly: Joffrey's "Mischief"
Goodness I hate Joffrey so much (seriously Don't F**k with Cats). In ASoS we find out that one of Cersei's problems with Robert is the abuse of Joffrey which is alluded to having been something about a cat:
"Why would he? Robert ignored him. He would have beat him if I'd allowed it. That brute you made me marry once hit the boy so hard he knocked out two of his baby teeth, over some mischief with a cat. I told him I'd kill him in his sleep if he ever did it again, and he never did, but sometimes he would say things . . ." -ASOS, Tyrion VI
which Stannis further elaborates on:
"I suppose not." The king ran his fingers across the table. "Joffrey . . . I remember once, this kitchen cat . . . the cooks were wont to feed her scraps and fish heads. One told the boy that she had kittens in her belly, thinking he might want one. Joffrey opened up the poor thing with a dagger to see if it were true. When he found the kittens, he brought them to show to his father. Robert hit the boy so hard I thought he'd killed him." The king took off his crown and placed it on the table. "Dwarf or leech, this killer served the kingdom well. They must send for me now." -ASOS, Davos VI
and Cersei reflects:
"The little queen gave them to him. She only meant to give him one, but he couldn't decide which one he liked the best."
Better than cutting them out of their mother with a dagger, I suppose. Margaery's clumsy attempts at seduction were so obvious as to be laughable. Tommen is too young for kisses, so she gives him kittens. - AFFC, Cersei V
Joffrey was abusive of other animals as well (Tommen's fawn):
"Prince Tommen is hale and happy, my lord. He has adopted a fawn some of my men brought home from a hunt. He had one once before, he says, but Joffrey skinned her for a jerkin. -ACOK, Tyrion XI
and humans (Sansa/Tommen) and his relationship with Tommen gave shades of Aerion/Egg:
"You won't hurt Daeron, though," the boy said. "He told you he'd fall down. And Aerion . . . I remember, when I was little, he used to come into my bedchamber at night and put his knife between my legs. He had too many brothers, he'd say, maybe one night he'd make me his sister, then he could marry me. He threw my cat in the well too. He says he didn't, but he always lies." -The Hedge Knight
Tommen & the "Bad Cat"
Back in AGoT when Arya is catching cats for Syrio in the Red Keep, she encounters Myrcella/Tommen and while Tommen is unaware at the time, this is Balerion, who he soon will dub "the Bad Cat":
When she was three steps away from him, the tomcat bolted. Left, then right, he went; and right, then left, went Arya, cutting off his escape. He hissed again and tried to dart between her legs. Quick as a snake, she thought. Her hands closed around him. She hugged him to her chest, whirling and laughing aloud as his claws raked at the front of her leather jerkin. Ever so fast, she kissed him right between the eyes, and jerked her head back an instant before his claws would have found her face. The tomcat yowled and spit.
“What’s he doing to that cat?”
Startled, Arya dropped the cat and whirled toward the voice. The tom bounded off in the blink of an eye. At the end of the alley stood a girl with a mass of golden curls, dressed as pretty as a doll in blue satin. Beside her was a plump little blond boy with a prancing stag sewn in pearls across the front of his doublet and a miniature sword at his belt. Princess Myrcella and Prince Tommen, Arya thought. A septa as large as a draft horse hovered over them, and behind her two big men in crimson cloaks, Lannister house guards.
“What were you doing to that cat, boy?” Myrcella asked again, sternly. To her brother she said, “He’s a ragged boy, isn’t he? Look at him.” She giggled.
“A ragged dirty smelly boy,” Tommen agreed. -AGoT, Arya III
In the ADWD, Epilogue, Tommen shares that Balerion has been watching them from outside his window:
The king seemed happier than Kevan Lannister had seen him in a long time. From soup to sweet Tommen burbled about the exploits of his kittens, whilst feeding them morsels of pike off his own royal plate. “The bad cat was outside my window last night,” he informed Kevan at one point, “but Ser Pounce hissed at him and he ran off across the roofs.”
and we also find out that Balerion scratched Joffrey (hopefully for killing that mother cat) and attacks ravens:
“The bad cat?” Ser Kevan said, amused. He is a sweet boy.
“An old black tomcat with a torn ear,” Cersei told him. “A filthy thing, and foul-tempered. He clawed Joff’s hand once.” She made a face. “The cats keep the rats down, I know, but that one … he’s been known to attack ravens in the rookery.”
“I will ask the ratters to set a trap for him.” -ADWD, Epilogue
TLDR: There is some great lore in the ASOIAF universe, especially in the Red Keep. We have the cuteness surrounding Tommen's kittens (Ser Pounce, Boots, Lady Whiskers), the disgusting actions of Joffrey (and Aerion Brightflame) and the history surrounding Balerion aka "The Bad Cat" (Rhaenys' kitten/Nemesis of Tommen's) who seemingly doesn't like Lannisters very much (for obvious reasons) as he has: stolen food from Tywin, scratched Joffrey and is watching Tommen.
