Male Cat Behavior Before Neutering. Their hormonal changes urge them to spray in order to mark their territory, welcoming females and setting boundaries for rival males. Some cats can still carry around a cranky attitude even after neutering, requiring some determination to find the cause and solution.
However, proper behavior training is still needed. Another unwanted behavior that is associated with intact male cats is territorial marking or spraying. A neutered cat will be less likely to develop these behavior problems.
