A cat in heat screams due to hormonal estrus cycles, and the most effective long-term solution is spaying, which eliminates the behavior entirely. For immediate relief, provide extra play sessions, calming pheromones, or a warm compress to soothe her. If you're also exploring new pets, note that gatitos siberianos disponibles are a breed known for their affectionate, quieter nature, though they still require spaying to prevent heat cycles. Never use human medications or scold her, as this worsens stress. Consult your vet about temporary hormone treatments if surgery must wait.
