Doukyonin wa Hiza, Tokidoki, Atama no Ue.

A bit similar the main characters and the same feeling while watching. A very warm feeling when watching in both cases. No fanservice, no traps, no useless drama or anything like that. Good comedy and a great piece of slice of life anime both. 

After debating the choices awhile, I found Barakamon to be a better recommendation for My Roommate is A Cat than Chi's Sweet Home. The 2 protagonists are surprisingly comparable. Both 23 years old, a calligrapher and writer respectively, they share very similar personalities as well as character design! Reclusive workaholics with poor people skills (particularly the latter who's more melancholy due to recent circumstances) both of them give and take offence quite readily. This is where both anime introduce the small, innocent, and adorable who slowly humanise the 2 young men, helping them connect with others and find simple pleasures in life. My Roommate is A Cat portray the healing powers a pet can offer, while depicting cat behaviour with delightful insight. Needless to say, the result is Cuteness Overload!! Barakamon, despite having less cats (well there's a part in ep.4 and Handa IS a cat-lover) is similarly wholesome in exploring the lead's endearing interactions with his neighbourhood children. If you enjoyed the comic yet heartwarming nature of Barakamon please watch My Roommate is A Cat. (Especially those who love cats! Also watch Chi's Sweet Home - it's simpler, shorter, and as sweet!)  read more 

they have the same vibe. we have a dude who needs help and has a lot of problems... so someone not expected comes to help, and it's amazing to see them together. in dooukyoin there's a kitten, and in barakamon, a little girl (which there's not much difference dfgdfhfgj) and in the journey of these two, more people appear to complete the path of our protagonist and is touching and cute and funny and beautiful and.. /sobs/ 

Both male lead is talented and socially awkward, until they face someone new who keep making them annoyed but also helping them to find happiness at the same time.  

Shut in artists learn to open up with help from children/cat. Mood is similar, these anime aren`t overly dramatic, but you can see even little things can have big meaning for those who feel strongly about those involved. Watching these is a great way to get you up from gloom and make you feel better by the power of niceness. 

-Both have a protagonist apart from society with curiously the same character design and suddenly a partner appears at all annoying 

Both anime are just so heartwarming and relaxing. Watching these will ease your heart and absorbs you to their innocent world. These two are my most effective chill pill. 

-The protagonist is a man who has a hobby of writing, and he takes care or spends time with a cat/child as well. -Comedy is interspersed occasionally, and these moments occur at certain scenarios. -Short amount of episodes. -Heartwarming stories, and slice of life. If you’re looking for anime that are wholesome and light-hearted, then these are subtle options plus there’s a lot of character depth in both shows.  

Wonderful story of a human-cat relationship told with the cat's point of view taken into account...(But Kanojo to Kanojo no Neko will make you cry hard. It's beautiful.) 

Both anime are about the relationship between a human and a cat and the story is told from both their points of view. Both human characters, at the start of the story, don't like having a pet that much (little Miyu from "Kanojo" was about to leave her cat, Daru, behind), but as the story proceeds the bond between them grows stronger.  

Basically replace a small girl with a small cat and you have the same kind of heartwarming story, with a similar kind-hearted cast of characters going through every day life.  

another iyashikei you will love 

Both anime revolve around the lives of pet owners and the adorable unpredictable behaviors of their little babies. Both are great for healing and soothing. 

Both stories involve the main character taking in a stray cat. The cats point of view is also shown in both cases.  

These animes are both great slice of lifes, will make you laugh out loud and have some endearing characters and moments that will pull on your heartstrings too. If you love hinamatsuri you'll definitely love my roommate is a cat :) 

Both of these series show our protagonist having to process and deal with getting on with life after the passing of their parents, through looking after another. In Gakuen Babysitters, this is a younger brother, in my roommate is a cat, it’s a cat. Gakuen babysitters has a slightly more light hearted feel, but both are cute and heart warming. 

They are both slice of life anime series in which the main characters try to live on their own while suffering from depression. These series also share similar comedy elements including cats and food, so if you are a cat person I think that you'll definitely be entertained watching these shows! 

This two anime are very similar wherein both MC lost their parents, then they met a cute partner/companion (A cat and in the other one is a Tanuki which has the ability to shapeshift into a cute kid.). Both anime also show where the companion was able to make the MC remember something they have/should have done when their parents are still alive. Both have same conclusion (almost) wherein the MCs have grown in mind.
