The 2025 FELASA Congress in Athens: From Aristotle to AI

The 16th FELASA Congress took place June 2025 in the cradle of science, Athens. Upon arrival, more than 2,000 professionals from 52 countries were welcomed by “Aristotle the Octopus”, a mascot alluding to Greek scientific heritage, Aristotle’s pioneering zoological observations and the values of intelligence, adaptability and ethics, which are central to laboratory animal science (LAS). The vibrant and friendly atmosphere was fertile ground for discussing advancements in LAS, regulation, education and ethics, but also for catching up with friends and colleagues, exchange ideas and start new collaborations. Having been involved in many aspects of the meeting – chairing sessions, delivering talks and workshops – we will share some insights and personal reflections on the meeting.
