The 3Rs – the ambition to where achievable decrease, refine, and, swap the use of animals – are recognized and accepted worldwide as the best framework for governing animal-dependent science, playing an integral purpose in guaranteeing superior criteria of moral consideration although also maximizing the opportunity for high-good quality science (Kirk, 2017).
