My overall score is 7, but I am sure some people will absolutely love this anime. I just found it ok, and it's a very subjective opinion. It was really cute, just not really my cup of tea.
Story: 7
I enjoyed the short stories each episode, but from one point they got a bit tiring - and for such a short episode I am not sure that's a good thing.
Art: 9
Probably my favourite part - because the cats are adorable and I loved seeing them in all shapes and sizes and costumes. The art was a lot of fun.
Sound: 7
Pretty ok.
Character: 7
This is not the type of anime we can discuss characters, but overall, I enjoyed the cats.
Enjoyment: 5
I admit I was only watching Micchiri Neko when I had 5 min to spare and wanted to do something - so I was watching an episode or two, but it's not like I was always looking forward to them or couldn't wait to watch them. They are not bad, as I said, just not the anime for me. Although it's really cute!
