New Cat Birth Control Shot: A High-Tech, Non-Surgical Alternative.

Scientists at the Cincinnati Zoo & Botanical Garden have conducted a three-year study that used anti-Mullerian hormone (AMH) gene therapy to prevent pregnancy in female cats. The treatment, administered as a single injection, raises AMH levels, which prevent pregnancy. The study observed six female cats who were given the AMH gene therapy treatment and three female cats who were not. None of the treated cats became pregnant and, after three years, did not show any negative side effects. This is the first non-surgical permanent option for female cats and could eliminate the need for spaying.
