A pack rat, often referred to as a hoarder, is someone who collects and keeps items that may seem unnecessary or worthless to others. This behavior can stem from various psychological factors, including anxiety or a fear of losing important possessions. Pack rats may struggle to discard items, leading to cluttered living spaces filled with various objects. Hoarding can impact a person's daily life, making it difficult to navigate their home or find essential items. It is recognized as a mental health condition, often requiring intervention or therapy to help individuals manage their collection habits and improve their living conditions.
