"If you see a stray cat with a cleanly clipped ear tip do not take it to a shelter. Either take it home to live with you or leave it on the street.

Clipped ears mean they were caught, neutered/spayed by the city/county, and released. This is a way to control cat populations and, over time, protect wildlife. They compete for resources with fertile cats without adding to the population.

In many cities, stray cats are more likely to be adopted from the street than in the shelter. If the cat is taken to a shelter they cannot legally release it because it is now abandoning the animal. That cat will be euthanized, or at best absorbs resources until it finds a home."
