If you're looking for anime similar to Chi's Sweet Adventure, you might like these titles.
It's a basketball! It's a melon! It's… Poyo the cat?! After drunkenly stumbling across the bulbous, cuddly creature on the street one day, Moe Satou decides to bring the stray home and keep him in the house as a family pet. Whether he's lounging around or bringing snacks to the other strays in the neighborhood, Poyo is always getting into a variety of misadventures with his new owners and friends, including the lovable neighbor cat Kurobe, doting father Shigeru and a host of kittens.
Loved the stories of Chii and her family and are looking for more? Try Poyoyo! It is also short-form anime about a cat who was adopted into a loving family. Each episode follows either Poyopoyo the cat or it's family as they deal with kitty mischief. While Poyppoyo isn't quite as cute as Chii, I think if you enjoyed one, you'd enjoy the other.
These anime kitty shorts perfectly compliment each other. One features the adventures of a sweet, cuddly adult cat and the farming family who makes him part of their household, the other shows the world through the eyes of a wide-eyed kitten and the young family who adopts her. Can't recommend them enough to other cat lovers like myself.
Chitose is a fluffy Emperor penguin chick living in Kyoto. The stories depict such familiar Kyoto locales as Togetsu-kyou bridge, Arashiyama Bamboo Grove, Fushimi Inari-taisha shrine, and Kiyomizu-dera temple from a penguin's perspective, as well as Kyoto cuisine.
Like Chi's Sweet Adventure, Chitose-chan is a sickeningly cute series with short-length episodes that will make you go "aww~". While the protagonists are quite different you'll enjoy Okoshiyasu, Chitose-chan if you liked Chi's Sweet Adventure.
What would happen if you started to peel a tasty banana, only to find an adorable kitty lurking inside? Bananya (“nya” is the Japanese word for “meow”) and all of his fruity feline friends are on the loose and having any exciting escapades. Will Bananya ever achieve his lifelong dream of one day becoming a trendy, chocolate-covered banana? One thing is for certain, you'll be in for a whole bunch of fun with this purr-fect collection of Bananya adventures!
Like Chi's Sweet Adventure, Bananya is an overly-cute short show featuring cats (well, cats in bananas to be precise) fooling around. Bananya might be sillier than Chi’s Sweet Adventure but if you’re in need of some diabetes-inducing cuteness give it a go!
What's Michael? Michael is a cat. A cat that is inexplicably attracted to the smell of raw fish, yet horribly repulsed by the smell of toothpaste. A cat that, in a dogfight with a fly, will strafe his master in her sleep. In short, Michael is a cat like any other cat.
The manga centers on a woman who is getting on in years, but all her cats think she's a man so they call her Ojii-chan. One day a brazen cat named Tsushima appears in Ojii-chan's yard.
