Castration using a chip in tomcats
Microchip castration—also called "chemical castration," "hormone chip," or "Suprelorin implant"—is a reversible alternative to surgical castration in male cats. A tiny implanted chip continuously releases a GnRH analogue, which severely reduces the body's own testosterone production. The result: The male cat becomes temporarily infertile, and typical sexual behavior (territorial marking, roaming, territorial fights, heat stress) decreases or disappears completely.
