Buttercup

Buttercup was a "hideous-looking tom cat" that belonged to Prim. He had a mashed-in nose, half of one ear missing, and eyes the color of rotting squash. Prim named him Buttercup because she insisted that his muddy yellow coat matched the bright flower. He doesn't like Katniss due to her attempt to drown him in a bucket, though they sometimes act friendly to each other. After Katniss starts to feed him the entrails from her hunting kills, he stops hissing at her. Buttercup is said to be a born mouser and even catches the occasional rat.

Buttercup sleeps with Prim and watches the area at night. He hisses at the sight of Katniss unless she feeds him. The cat moves to the Victor village after Katniss won the 74th Hunger Games, but dislikes the house and often returns to their old home in the Seam. Once Katniss finds him in her old home, she tells him he is a ugly cat which he replies by nudging her so he could be petted. Katniss feeds him some of her kill and rubs in between his ears. The two bond together with this and their dislike of their new home. Katniss scoops him up into her arms and leaves the old home. When she lets him go, Buttercup runs away and hides under a bush. He returns to the new house in Victor Village and sleeps with Prim again. Prim cares for him and always holds and pets him. Buttercup comforts her once again when Katniss is reaped in the Third Quarter Quell.

Buttercup the cat also appears in the final installment of the series, Mockingjay. When Katniss returns to the destroyed District 12, she goes to the remains of her house and finds Buttercup there, as apposed to Prim's goat, Lady. Katniss figures, sarcastically, that Buttercup had to live, not Lady, because Lady actually served a purpose in the household. Katniss also finds her family's plant book, a ribbon, and her father's hunting jacket in Katniss's house in Victor's Village.

Also in Mockingjay, Buttercup and Katniss play a game of Crazy Cat, invented by Katniss, where she shines a light on the wall and Buttercup becomes determined to catch it. Buttercup's reactions to the light are similar to what Katniss' reactions would be if the light was Peeta Mellark.

Buttercup is stuffed into Katniss' hunting bag, and Prim cries when she sees him. One of Katniss' demands is that, if she becomes the Mockingjay for the rebels, Prim will be able to keep Buttercup. This request is accepted, and he is allowed outside for a few hours of the day, and be with Prim as he pleases.

Buttercup is almost the death of Prim in Mockingjay. She is looking for him, and word has spread that there will be a bombing shortly in District 13, as Peeta subtly slipped in to the broadcast. Katniss realized that Prim is missing, and assumes that it must be because of the cat. If Peeta had not made the announcement, Prim and Gale would have perished in the bombing. Buttercup lived in the bowels of District 13 with Mrs. Everdeen, Katniss, and Prim. He slept next to Prim in her lower bunk. Katniss holds him by the neck since he almost killed Prim but she lets go after Prim asks her to. The two sleep together during the night in the bunker. Katniss plays with him during the night with a flashlight, and pretends to be him to imagine how to get Peeta back.

After Prim's death, Katniss returns once more to District 12. Buttercup travels all the way from District 13 to District 12 to find Prim. She finds Buttercup, and is enraged. He looks at her, in hope for Prim, and she screams furiously that Prim is dead, and that he should leave. He does not, and they mourn Prim together, until she comes to accept him.

Together Katniss and Buttercup cry about their lost loved one. Katniss cries into his fur and he rests his head on her. They both get along because they only have each other. Katniss has Peeta, but he doesn't know Prim as well as Katniss and Buttercup.

Primrose Everdeen
Prim had a strong relationship with her cat, Buttercup. Prim found and healed Buttercup and later she tried to stop Katniss from drowning him and kept him as a pet. Prim would always sleep with him and he would always watch over her during the night to make sure she would stay safe. In Catching Fire, though he did not like the new house he lives in with the Everdeens in the Victor Village, he would often leave but come back for Prim. In Mockingjay, the two were glad to be able to be with each other after Katniss made a request to keep Buttercup for Prim's sake. He continued to protect her over the night and slept by her. Prim was willing to be killed for Buttercup after she almost died during the bombing of District 13 by the Capitol. Prim realized he was still in her room and went there to retreieve him so he wouldn't be killed but both of them would have died if not for Gale. Buttercup traveled all the way from District 13 to 12 just to find Prim but was sad when he did not find her. Katniss yells at him "She's dead!" and the two mourn together for Prim. Katniss keeps Buttercup as her is the only thing left of Prim.

Katniss Everdeen

In Catching Fire, Katniss and Buttercup both disliked the new house at the Victor's Village and often visited the old house at the Seam. Katniss saw he was there and rubbed his stomach, she says that is the first time the two ever bonded together. In Mockingjay, Katniss brings him with her to District 13 for Prim's sake after she finds him at their destroyed house at the seam. She although stuffed him in a hunting bag and hit him on the stairs which cause him to hiss and try to escape. Katniss made a request for Buttercup to stay with them and be able to go outside for a while and he could stay with Prim. After the bombing, Katniss held a grudge toward him after he almost killed Prim by her returning to their compartment to retreive him and take him to safety during the bombing.
