GnRH Immunocontraception for Humane Control of Feral Cats
Feral cats are a worldwide problem and are frequently controlled by euthanasia. Non-surgical sterilization offers the promise of a low-cost humane solution that does not require the cats to undergo surgery. The purpose of this study is to investigate the effectiveness of a GnRH-based vaccine for contraception in female cats. This study is still in progress. So far a single dose of vaccine has prevented pregnancy in 73% of cats for 27 months and 40% of the cats for 48 months. This vaccine has the potential to improve feline welfare by increasing access to humane population control options throughout the world.
This study is being conducted by John Friary and is funded by Morris Animal Foundation.
