A pet yukkuri making children without her owner's permission, either between 2 pets or between a pet and a stray. Tag is also used for stray yukkuri who's stated or implied to be abandoned pets who was abandoned because they refreshed without permission.
Most pet yukkuris are sternly taught by the shopkeeper and their owner that they are forbidden from having children. However yukkuris view their children as angels and as such some pets would breed anyways believing that once their owner sees how easy their children are, they will be forgiven. This of course is not true and it often leads to either abandonment or abuse where their children is tortured and killed in front of them.
