From Nookipedia, the Animal Crossing wiki
Ankha (ナイル, Nairu, Nile) is a snooty, cat villager in the Animal Crossing series, appearing in every game except Doubutsu no Mori and Animal Crossing: Wild World. She was originally intended to make an appearance in Wild World, but was replaced by a new character called Anabelle. She reappeared in Animal Crossing: City Folk. In Doubutsu no Mori+, Animal Crossing, and Doubutsu no Mori e+, she is an islander. Her name is based on the ankh, which is the Egyptian hieroglyphic character that reads "life." Her Japanese name is based on the famous Egyptian river, the River Nile. Her catchphrase relates to her arrogant "snooty" personality, by saying "me," and a sound a cat makes, "meow." Egyptians worshiped cats, and had a cat god, which may be where the idea for Ankha's design came from.
Her headgear was worn by Queen Cleopatra, the Hellenistic ruler of Egypt. Ankha is a navy blue-and-gold-striped cat, with black eyeliner in the style of Egyptian royalty (black around the eyes, then wings out towards the outside of the eye). She has a slightly different style in City Folk, where she lacks the normal pharaoh headdress, which is now replaced with a head pendant, but it was changed back to a headdress in New Leaf.
Below is a brief description of the snooty personality. For more information, look at the main article found here.
Ankha has a snooty personality, which means she will appear arrogant and snobbish towards the player and other villagers, but will appear friendly and nice in some discussions, provided they are mature and do not insult her lifestyle. She finds appearance important, and will get angry or upset if someone criticizes her sense of style or fitness, which means a conversation between her and a jock personality may leave either one upset or angry. Her attitude towards the player changes, as she begins to warm up to them, but she will still retain some arrogance and subtle rudeness. She may not get along with lazy villagers, due to their lifestyles - lazy villagers having a strong interest in food or relaxing, both of which will make her uncomfortable, angry, and upset when in conversation. She will upset peppy villagers, usually by gossiping about them, and finding small things to judge them on. She will get along well with normal, cranky, and other snooty villagers. She initially wore a Red Aloha Shirt.
In the first Animal Crossing, Ankha's house has an island look. She will ask the player for the Harp, Ivory Piano, Pachira, Regal Dresser, Regal Vanity, Retro Stereo, White King, and White Queen for her house.
In Animal Crossing: City Folk, Ankha's house instead takes on an Egyptian look. She has the Ancient Wall and matching carpet in her house. She also has a pyramid, a sphinx, and a birdcage. If she gets a stereo it will play "Marine Song 2001."
As an islander in Animal Crossing for GameCube, she has a favorite fruit and a fruit that she is allergic to. Feeding her the latter fruit will reduce the likelihood of her dropping bags of money. Ankha loves cherries and is allergic to apples.
