Eartipping is an effective and universally accepted method to identify a spayed or neutered and vaccinated feral cat. It is the removal of the distal one-quarter of a cat’s left ear, which is approximately 3/8 inch, or 1 cm, in an adult and proportionally smaller in a kitten.
This procedure is performed under sterile conditions while the cat is already anesthetized for spay or neuter surgery. There is little or no bleeding, it is relatively painless to the cat, and the eartip does not significantly alter the appearance or beauty of the cat.
