Hello I'm tomosteen.
I know that the song in the video has different song titles in different countries.
This song is called "ねこふんじゃった" in Japan, and I arranged it hard.
The little bit of guitar sound you hear in the middle of the song is me playing it.
The cat in this video is "ネコのペンおき", which is sold in Japan.
The cat in this video is not a promotion for a company, but I used it because I like it.
