Many countries continue to allow the use of non-domesticated animals, such as tigers, in travelling circuses, as introducing legislation or bans often requires sufficient scientific evidence that the environment negatively impacts animal welfare. Whilst we know that larger territorial animals are least suited to captive environments, to date there has been very limited investigation into the welfare of tigers in travelling circuses. By reviewing the scientific evidence available on the topic, this paper suggests that the travelling nature of a circus often negatively impacts on the suitability of the physical environment for tigers, as well as their nutrition, health, and mental state. However, training for performances could positively impact welfare, dependent on the techniques used. Nevertheless, the preponderance of the scientific literature supports additional nationwide bans on the use of tigers in travelling circuses internationally, due to animal welfare concerns.
