Humans are categorized by two different species. The most common species who takes up 70% of the population are known as Kakuen or ape-man. Just like its name, they originated from monkeys. They cannot control the visibility of their soul's nor they can see the other souls manifestation. On the other hand, the remaining 30% of the population are called Madararui, or zoo-man, who have the ability to see the manifestation of other people’s soul and can control their own shape. To our protagonist Norio, who has been the target of unwanted attention, must have been in shock when he learned that he is now part of that 30%.

Norio used to consider himself an average guy, well, that is, after an accident that awakened his Madararui side. He is an ape-man and zoo-man hybrid in which he falls under the nekomata category. His soul's manifestation is that of a brown cat with white fur around his face, up to his belly. Norio easily lets his emotion get the better of him, but this attitude of his is what makes him fun and appealing.

Mamiya, Sakura has seen ghosts since the time she has been spirited away during her childhood. Now at high school, she unexpectedly uncovers the truth behind her classmate Rokudo, Rinne. He is a human and Shinigami hybrid who guides souls to be reincarnated once again.

Rokumon is the black cat that formed a contract with Rinne as his aid and support. Originally, his true master is Rinne’s grandmother, Tomoko, who just fired him. Thankfully, with Rokumon's endless persistence and persuasion, he manages to make a contract with his new master, albeit with the price of taking care of his own expenses. Loyal and lovable, he makes the perfect partner for Rinne. He exhibits three forms that can be quite beneficial to Rinne and to himself.

His first form is his a humanoid look that he usually uses, the second one is his full on cat form which he uses to lure people to give him food, and lastly the third form in which he transforms into a big scary demon cat that can be of use, especially for traveling. His actions may look misguided, but this devoted cat boy has nothing but good intentions in mind.

Show by Rock!! Presents a lot of kemonomimi characters where it follows the story of a shy young girl named Hijirikawa, Cyan, who was pulled inside in her favorite rhythm game. In the game, there is a place called Midi city where music rules all things. Just like Cyan who joined the Plasmagica to be the best band in the city, Shingan Crimsonz also aims to be the top band.

There are actually two cat boys in the group Shingan Crimsonz. Aion is the lion guitarist of the group while the other one is Rom, who is the leopard drummer of the group. Since they are band mates and is in the same feline family, why not have them both in our 8th place. Aion is one of those characters who likes to strike poses. He looks at himself with high regard and loves any attention that is given to him. Meanwhile, Rom is the most responsible and most persuasive out of the group. Even though he is not the leader of the group by name, he acts as if he is one. Despite him using his fists to talk and convey his feelings, Rom is usually the one who pulls his bandmates back together when they go astray. If you want to see more of them, go check Show by Rock!! Short! which would have been aired by now.

Based on the Otome game with the same name and also loosely based on Lewis Carroll’s Alice’s adventure in wonderland, comes the very bizarre and confusing world of Heart no Kuni no Alice. Well, in any story that is based on Alice in wonderland, it is expected that it’ll be a bit weird and this show is no exception. The basic plot is not that different from the original. Nevertheless, Quin Rose manages to make it their own by creating its unique colorful world and its characters. Our heroine’s name is Alice, who found herself waking up in a world that is different from what she knows. As she starts her adventure to get back to her own world, she meets different characters that will give her some hint of the purpose why she is in wonderland.

One character that Alice meets is Airay, Boris who is based on Cheshire cat. Like its original counterpart, he loves riddles and is quite a mischievous character. What makes him an interesting character is that he loves to create and make weapons. Swords, guns, axes to bombs, you name it, he can make it! Just like any cat, he is laid back, carefree and pursues anything that has piqued his interest.

Much like our selection above, Pandora Hearts also takes the reference on Lewis Carroll’s Alice’s adventure in wonderland. Oz who just turned 15 was thrown into the dark place of the Abyss. Now feeling lost in the horrific world of the abyss, his only salvation is to form a contract with a chain named Alice not knowing that he will swirl down in the rabbit hole even more.

Do you see the resemblance between Cheshire cat and Airay, Boris from Heart no Kuni no Alice? They are like two peas in a pod, especially since they are based on Carroll’s Cheshire cat. Similar they may be, Pandora’s Cheshire exhibits more of a darker persona. Prior to the beginning of the series, he was Alice’s precious pet cat who once holds the truth from 100 years ago in his bell that was given to him by Alice. Cheshire has a lot of forms in which they all resemble a cat. Towards the intention, he can be very sweet and affectionate but once he sees the displeased intention in something, he will not hesitate to shed blood to wipe away anything that threatens his master’s happiness.

With the dark atmosphere that Hellsing Ultimate gives, a certain werecat character loiters around the series with his cute childlike appearance and fun personality. Yes; we are talking about Schrödinger of Hellsing, who is part of the Millennium Organization and is under the direct command of the Major. He was created by Doc with the purpose of being a spy, messenger, and somewhat a pet cat for the Major, who in turn is quite fond of the cat boy.

He was named and referenced after Schrödinger’s cat experiment in that he can be everywhere and nowhere; to simply put when he thinks and believes in that certain mindset, then it will be. It is quite complicated in a way, but this is what makes him one of the omnipotent characters in Hellsing besides Alucard. In spite of being on the villain's side, what is not to like about Schrödinger? Schrödinger is cute, charming, and playful, just what we would expect from such a likable character of the series.

Leo is a celestial spirit that uses magic regulus for combat. He is known as the Lion and is the leader of the 12 golden celestial keys. His story began when he was under the command of a celestial spirit mage named Lilica, Karen. Since his former master has been an abuser to his friend Aries; he made sure to stay on earth, making Karen unable to summon other celestial beings. Leo stated that he will only go back and open the gate with the condition of Karen breaking her contract with him and Aries which Karen immediately refused. Days turned into weeks until Loki finds out that Karen died while being on a mission. Blaming himself for her death, he took up a new identity as Loki and joined the Fairy Tail guild.

Loki is your typical playboy who endlessly flirts with girls. However, he is responsible and he can show great concern for his friends. Loki is very loyal to his current master Heartfilia, Lucy and takes any opportunity to make a move on her. In his celestial form, you will see his Lion ears on top of his head with his orange hair, sporting his lion mane.

After finishing his first day at school, Aoyagi, Ritsuka meets an enigmatic man named Agatsuma, Soubi, who claims to be a good friend of his big brother Seimei. Through Soubi, Ritsuka was introduced to the world of spell battles where it must be done by having a sacrifice and a fighter with the same name. The sacrifice is the one who takes the damages and is the master among the two while the fighter, as the name suggests, does the fighting and the servant between the duo. With now having the power to fight, Ritsuka, together with Soubi, search the Septimal Moon to find the truth behind the death of Seimei and the cause of his amnesia.

In the world of loveless, everyone is born with cat traits such as cat ears and cat tails; it also symbolizes purity and innocence. The only way for these cat traits to disappear is through sexual intercourse. Aoyagi, Ritsuka is on our list because he still retains his cat boy form. Ritsuka, or loveless, is a 12-year-old boy who displays intelligence and maturity pass his age. Despite this, our little cat boy is shy and naive when it comes to love. He can be cold and frank at times, but with the complexity of his character and the way he approaches tough challenges head on, the show becomes more engaging and entertaining.

Honda, Tohru’s supposedly normal life turns upside down when she finds herself living with Souma, Yuki, together with his uncle Shigure and cousin Kyou. Every day must have been quite an adventure to her, most especially when she learns the secret behind the smash’. Some of the members of the Souma family, with Kyou having a special case, are cursed to transform to their zodiac animal spirit when they are weakened, emotionally distressed, or when they are touched by someone from the opposite sex. It is now up to Tohru to understand each one of them and somehow help them break the curse.

As stated earlier, Kyou’s case is special because he is haunted by the spirit of the cat who unfortunately fell in the rat’s trickery and wasn't able to be one of the animals included in the 12 zodiac signs. Kyou’s aggressive and hot head personality stemmed from within to protect himself. Regardless of this, he hides his softer side with only a few people who are able to see it. Since he is a cat boy, he has mannerisms that strongly resembles that of a cat, loving the taste of milk and fish, being startled easily, likes high places and hates being restrained. Furthermore, he is agile and fast. Being a cat, he cannot stop hating on Yuki, who is a rat and therefore a natural enemy of his.

Shugo Chara! tells us the magical adventure of Hinamori, Amu who wishes to show her real self to others. With this wish, three guardian characters were born to help fulfill her dream. She eventually lands a place in the student council (who also has their own Chara) as the joker who can wield the power of the Humpty Lock and cleanse the X-Eggs, as well as, the X-Characters. She eventually meets Ikuto and his Chara Yoru, who are part of an organization named Ester Company. They are in search of the Embryo that grants any wishes, but the process of extracting a Heart’s Egg can lead to the dreams it holds being tainted.

These two are together simply because they can also be considered as one entity. After all, Yoru is the embodiment of Ikuto’s desire to be free like a stray cat. Ikuto can change or transform into a cat boy with the help of his Chara, Yoru. Although Yoru is Ikuto’s would be self, both do not essentially have the same personality; well... except for the part that they like teasing people around them. Ikuto has more of a mysterious vibe surrounding him. He is more or less indifferent and is quiet most of the time.

Nonetheless, he has a sweet, caring personality who becomes selfless when those who are close to him are in danger. Meanwhile, his sidekick Yoru shows a more selfish playful attitude who loves to say, "nya"! He loves to wander around looking for something to humor himself with or someone to make fun with. Ikuto being our ideal bad boy and Yoru with his abundant charming traits, what more do you need to ask for? They are the perfect cat boy package! nya~
