In Havana, there are so many unsterilized dogs and cats that some people try to kill them just to try to keep down their populations. But some of these dogs have been adopted by various public buildings and areas. They wear laminated name cards around their necks that say, “Estoy esterilizado,” which translates as “I am sterilized,” meaning that they have been spayed/neutered. The tags also tell where they live and say, “No me maltrates,” which means, “don’t mistreat me.”
