Di Gi Charat Nyo

they are very similair sci-fi setting, catgirls, random humor, if you liked either of these, you should try this one. 

same creators, they are very similar to each other, you can expect the same nonesense humor. 

Moe anthropomorphism design aside, Etotama and Di Gi Charat Nyo has an energetic albeit dumb female main character that freeloading with their human tenant. It has the similar type of gag comedy and puns along with the occasional breaking the 4th wall. There is also a common trope of strong rivalry with one of their anthropomorphic kin and occasional friendships bonding and battle. The themes on Di Gi Charat Nyo is more random as it was composed of short gags of their daily life, while Etotama is mainly focused on the battle-of-the-week that is done by Nya-tan. Although judging by their appearances, they might seem comparable, Dejiko is not a real 'catgirl' like Nya-tan, however, their mischievous and whimsical nature is very much alike, they also have a cat like verbal-ticks at the end of every sentence. I highly recommend this series for the gags and parody. read more
