Revolutionary contraceptive injection offers non-surgical solution for managing cat populations.

Scientists at the Cincinnati Zoo & Botanical Garden have developed a single-dose contraceptive injection for female cats that could help control the 480 million population of feral or stray felines worldwide. The treatment involves the Anti-Müllerian hormone (AMH), which connects to receptors in the ovary and helps regulate ovulation. The injection is administered into the animal's thigh muscle while they are awake and could be used on other species in the future. The researchers hope to help alleviate the strain caused by the estimated 480 million domesticated cats across the world who are feral or strays.
