Eartipping is the universal sign of a cat that has been spayed or neutered. The procedure involves removing a very small piece of the tip of the cat’s left ear in a straight line cut. This is done while the cat is anesthetized for spay/neutering and healing is rapid.
The procedure allows those that TNR the ability to identify if a cat has been spayed or neutered without having capture them.
“Trap-Neuter-Return, commonly referred to as “TNR,” is the only method proven to be humane and effective at controlling feral cat population growth. Using this technique, all the feral cats in a colony are trapped, neutered and then returned to their territory where caretakers provide them with regular food and shelter. Young kittens who can still be socialized, as well as friendly adults, are placed in foster care and eventually adopted out to good homes.”
“TNR has many advantages. It immediately stabilizes the size of the colony by eliminating new litters. The nuisance behavior often associated with feral cats is dramatically reduced, including the yowling and fighting that come with mating activity and the odor of unneutered males spraying to mark their territory. The returned colony also guards its territory, preventing unneutered cats from moving in and beginning the cycle of overpopulation and problem behavior anew. Particularly in urban areas, the cats continue to provide natural rodent control. ”
