Opossums, known as possums in some regions, are marsupial mammals that play a vital role in pest control in Quintana Roo. These animals are key to maintaining the ecological balance as they feed on insects and small animals considered pests, such as cockroaches, tarantulas, ticks, horseflies, scorpions, bedbugs, and even venomous snakes. Their role in pest control is essential to the state's ecosystem, helping to manage species that can be harmful to human health and well-being. The presence of opossums can also reduce the need for chemical pesticides, promoting a healthier environment. However, despite their benefits, opossums often face mistreatment and cruelty, primarily due to their appearance.

The Quintana Roo State Animal Protection and Welfare Law protects these animals, imposing severe penalties for acts of cruelty. These penalties can include fines exceeding 21,700 pesos and up to two years in jail.

To report an attack on an opossum, individuals must submit the case to the State Attorney General's Office (FGE). They should provide visual evidence of the attack, the location of the incident, and if possible, the name of the perpetrator. This process aims to deter mistreatment and encourage the protection of these valuable animals.

In January and February of 2024, the state has addressed 65 cases of injured opossums from various municipalities, with 14 instances of extreme cruelty resulting in the death of 12 animals. The attacks have included machete assaults, burns, and hangings. Additionally, 43 opossums have been hit by vehicles, caught in traps, or injured by other animals, such as domestic dogs. Most of these cases were reported in Cancun, with the remainder spread across Puerto Morelos, Solidaridad, and other municipalities.

The association Tlacuatitlán is dedicated to helping these animals. They respond to rescue calls, take the animals to veterinarians, and later release them. Citizens are also encouraged to take injured opossums to a veterinarian. To raise funds for aiding the opossums, the association is planning a bazaar, "Tlacuabazar", on Saturday, July 13th in Puerto Morelos, starting at 14:00. The association's founder emphasizes the need for public education about the importance and benefits of opossums to prevent future acts of violence against them.
