Wildlife trade, exploitation in research, animal farming or the use of animals for entertainment are all threats to the physical and mental wellbeing of animals [1-4]. Welfare standards, when it comes to the treatment of animals, vary depending on geography and context and are highly debated amongst animal welfare groups, academics and legislative bodies [5,6].
Although most people can agree that animals should be treated humanely, the description of “humanely” varies for everyone, making global animal treatment monitoring a complex issue.
Disturbing reports of the cruel treatment of animals are still frequent. As well as inhumane treatment of animals that might be considered “normal” in mainstream society.
