Which behavior is reduced by neutering male animals?

  1. Decreased bonding

  2. Increased aggression

  3. Marking behavior

  4. Increased hunting instinct

The correct answer is: Marking behavior

Neutering male animals is particularly effective in reducing marking behavior. This behavior, which often includes urinating in various locations to establish territory, is closely linked to testosterone levels. When a male animal is neutered, the production of testosterone is significantly decreased, resulting in a reduction of behaviors driven by this hormone, including the urge to mark territory. This can lead to a cleaner living environment for both the animal and their owners and typically promotes more socially acceptable behavior within the household. By tackling the underlying hormonal impulses, neutering directly addresses this specific behavior, leading to its reduction.
