My neighbour brings back every stray he traps with a small notch cut in one ear, and it’s not from an old fight
That small triangular nick in a rescued cat’s ear isn’t a wound—it’s an internationally recognised surgical mark called ear-tipping. It signals that a cat has been neutered, vaccinated, and returned to the streets as part of a Trap-Neuter-Return programme, preventing unnecessary re-trapping and stress.
