The sterilization of an animal.

Removal of genitals from the animal.

Desexing an animal by surgical removal of the reproductive organs

an operation that stops an animal from reproducing

Male castration involves removal of the testicles. Un-neutered males not only father unwanted kittens, they also mark their territory with offensive-smelling urine, and get involved in cat fights with other toms, spreading infectious diseases. The operation is simple, painless and safe, and results in a much calmer and affectionate cat.

Neutering, from the Latin neÅ­ter (of neither type), is the removal of an animal's reproductive organ, either all of it or a considerably large part of it. It is the most drastic surgical procedure with sterilizing purposes. The process in males is also referred to as castration, or gelding; while the process in females is also called spaying.
