Neko nanka Yondemo Konai.

Hoomans take in cats. Both series are funny, warm and fuzzy. But there are also some hints of sadness especially in episode 2 of Ore, Tsushima and episode 6 of Neko nanka Yondemo Konai. Follow the daily lives of Ojii-chan and Tsushima + his other cat pals in Ore, Tsushima, and Mitsuo, Chin and Kuro in Neko nanka Yondemo Konai. 

Both anime have short episodes telling the daily life of living with cats in a cute and fun way 

Neko Nanka and Kremlin are short comedy ONAs about a loser man living with troublesome kittens. 

Both animes revolve around a person taking in an adorable cat (or two!) into the household, and adjust to a normal life with them. Both series' episode lengths are very short, making it very easy to get through the series, especially if you don't have that much time. the only differences would be that Poyo takes place in a country-like setting, Neko Nanka takes place in an aprtment, and it seems like I enjoyed Poyopoyo a bit more than Neko Nanka.Both series are definitely good shows for cat lovers, and for anyone who loves cute little shows. 

Cute cats doing cute things and being the boss of the household. Intended for those who enjoy cat shenanigans
