African green monkeys (Chlorocebus sabaeus) were introduced to Saint Kitts in the 17th century and have proliferated across the island. With an estimated population of 35,000-50,000 — outnumbering humans — they create significant agricultural damage and human-wildlife conflict. Management approaches have historically included culling, creating welfare concerns.
The Behavioural Science Foundation (BSF) on Saint Kitts conducts biomedical research on the vervet monkey population, raising ongoing ethical and welfare debates about the appropriate use of these animals in research contexts. International welfare organizations have engaged with the BSF on improving research animal welfare standards.
The Prevention of Cruelty to Animals Act provides basic welfare protections for companion animals and domestic livestock. The legislation does not specifically address the complex welfare and management issues posed by the feral vervet monkey population. The Ministry of Agriculture works with affected farming communities on human-wildlife conflict mitigation.
Saint Kitts and Nevis beaches provide nesting habitat for hawksbill, leatherback, and green sea turtles. The Saint Christopher Heritage Society and other organizations conduct monitoring programs. Traditional sea turtle harvesting has historical roots, with conservation efforts focused on shifting practices toward observation-based tourism.
The Ross University School of Veterinary Medicine on Saint Kitts operates one of the Caribbean's most significant veterinary training institutions, providing some veterinary capacity for the local animal welfare system. The university conducts outreach programs including spay/neuter campaigns for local companion animals.
The waters around Saint Kitts and Nevis support diverse marine life including sea turtles, reef fish, and occasional marine mammal visitors. Recreational and sport fishing intersect with marine welfare, with reef protection regulations providing indirect welfare benefits to marine populations.
