Wild Cats in Latin America Threatened by Domestic Pet Diseases

Diseases carried by domestic dogs and cats are increasingly endangering wild felids such as jaguars, pumas and ocelots across Latin America. Researchers have identified viral, bacterial and parasitic infections—including canine distemper, sarcoptic mange, feline leukemia and panleukopenia—spreading from unvaccinated pets to wildlife, especially where human settlement, roads and stray animals encroach on protected habitats.

The problem has been documented in several countries, including Mexico, Costa Rica, Ecuador, Bolivia and Colombia. Experts say that, beyond habitat loss and illegal hunting, these health threats could cause severe declines in already vulnerable predator populations. They recommend expanding vaccination and health monitoring of pets, preventing abandonment in rural and protected areas, and strengthening wildlife surveillance programs to curb disease transmission.
