24. Minks

Minks are semi-aquatic predators known for their agility and strong territorial instincts.
In captivity, they often display aggressive and destructive behaviors, making them difficult and even dangerous to manage. Minks require highly complex environments with access to water and ample space to thrive—needs that are nearly impossible to meet in a household.
As National Geographic points out, the American mink is not suitable for domestic life.
