Why Trap Vasectomize Return and Trap Vasectomize Hysterectomize Return are Better Than Trap Neuter Return
The reason trap-vasectomize-return (TVR) and trap-vasectomize-hysterectomize-return (TVHR) are better than trap-neuter-return (TNR) is because the latter exacerbates the issue of too many feral or free roaming cats if there too many. Cats in the wild form colonies, and those colonies have ranks. Castrated and spayed cats lose their rank and cause the fertile cats to make more babies to compensate for the cats that have been gonadectomized. Desexed or eunuched non-human animals, including cats and dogs, are often treated poorly by other members of their families or groups.
Because gonadectomized cats returned to the colony cause the fertile cats to make more babies than if the colony were just left alone (no cats TNRd or killed), castration and spaying may even make the issue of overpopulated free roaming cats worse than if they were just left intact.
Cats who have had vasectomies, tubal ligations, and ovary sparing spays however, give other cats the illusion that they’re fertile. They can sense when another has no hormones. So when they have had vasectomies, tubal ligations, and ovary sparing spays, they maintain their ranks and they are at the same time infertile. In other words, they can still attempt to breed but they fail to do so. This helps to reduce the numbers much better than castration and spaying does.
