FAWI – about Cats With No Names
Currently, there are no injectable or oral contraceptives that are safe, affordable and effective to decrease fertility in cats.
Thus far, Dr. JSF has been in contact with USDA regarding a promising immunovaccine in cats, GonaCon, and possible field application in Curacao (Animal Aid Curacao) following the excellent work of Dr. Julie Levy at University of Florida.
Until such a vaccine is commercially available, we recommend TNR-F programs (Trap Neuter Return – Follow up) to help stabilize feral cats populations and their wellbeing.
