Cat semi-owners" might refer to individuals who have a relationship with a cat but don't have full ownership responsibilities. These individuals may care for a cat temporarily or occasionally, providing some care or companionship without being the primary or permanent caregiver. For instance, someone might frequently feed and spend time with a neighbor's cat, offer occasional pet sitting, or assist in caring for a friend or family member's cat without having the formal title of an owner. These semi-owners might not be responsible for all aspects of the cat's care, such as veterinary visits or major decisions, but they still play a role in the cat's life and well-being.
