Wild animals in travelling circuses face significant welfare challenges from transportation, confinement, performance training, and inability to express natural behaviours.
Circus animal welfare failures arise from the fundamental incompatibility between the animals' needs and the travelling circus environment: transport confines animals for days, venues provide minimal space between performances, and training for unnatural acts causes stress and sometimes injury. The UK ban represents recognition that these welfare compromises cannot be justified by entertainment value. International campaign work to extend bans globally continues, as animals in circuses in many countries still experience these harms.
