This is an extra chapter at the end of either the Neko Neko darling or Neko Neko Neko honey series.
They are both related series that follow members of a family that transform into cats when they get emotional.
Neko Neko darling follows the younger brother and is the first series.
Neko Neko honey follows the older brother and gives insight into other family members. If I remember correctly this is the extra chapter that finishes this series.
