If you liked the Catman anime, the Anime-Planet community thinks you'd like:
Every town needs a hero. Unfortunately for the human residents of Dark City, theirs is a stray cat. Swooping from roof to roof, its first thought is always of food or being able to catch an elusive mouse – saving the day is just a fortunate side effect. From rescuing lost children to putting a stop to careless littering, Dark Cat finds himself caught up in numerous problems – though caring about none of them. As his name spreads, he finds himself the center of attention as reporters desperately try to snap the unlikely hero. Cheeky and mischievous, this feline favorite wants to protect his kind; but can this renegade kitty stay out of the clutches of a mayor determined to rid the city of strays?
Both series take a look at cats in the human world that cause interesting situations. Dark Cat actually has humans in the show where Catman turn cats into human like beings living out their daily lives. Both have a interesting soundtrack that helps the viewer feel more about the show, especially in Catman. Both are abstracty in their style and have short episode lengths, if you liked one I'm sure you'd enjoy the other.
Both Catman and Ankoku Cat are hort animations that focus on a less than normal feline. Though Ankoku Cat is more of an anti-hero, and Catman simply apathetic, both are characters that live outside of society's norms. Though the animation of both isn't particularly amazing, both heavily utilise music, so if you like one, you may enjoy the other.
Dark Side Cat and Catman both feature, as their names imply, feline main characters. The other one is a hero and the other, well... a little less so. Flash animation was used in the making of both titles, so if you liked the style in one, watch the other too!
Four touching and intriguing stories are set to a backdrop of different songs: a futuristic cop patrols the streets to fight against crime; a girl experiences an out-of-this-world vision of the world after ingesting a variety of pills; a badass battling chick fights her way to happiness and manages to stoke the flame of love; and two lovers meet and exchange a beautiful rose.
OK, this may seem like an odd rec on the surface, but both Catman and Amazing Nuts are short anime where music plays a very important role. In both cases the soundtrack is the only form of sound, which accompanies a stylised form of animation. While Catman's animation quality is far lower than that of Amazing Nuts, it's worth checking one out if you enjoyed the other.
His name is Tortov Roddle, and he is a traveler from Tortalia. Along with his unusually large companion of a pig, the slender Tortov travels from place to place, always finding a new and beautiful adventure at his destination. From islands carried on the backs of frogs, to delightful cafes, to movie theaters and giant bears, there's a wonderful story to tell in the diary of Tortov Roddle.
These two series might seem very different, but I find them somewhat similair. While Tortov Roddle is more slow-paced fantasy and Catman action-packed and foul-mouthed, both are shoet web series with unique styles that set them apart from the masses. They also follow a lonesome traveller of his own road.
