This is a very interesting website that shows the achievements of the National Committee for the Protection of Animals Used for Scientific Purposes. The link is: http://english.ncadierproevenbeleid.nl. They have created very useful guidelines on pain detection, genetically modified animals and alternatives to standard methods of killing.
Very active Committee!! ...whose website is worth visiting

RABBIT GRIMACE SCALE AS INDICATION OF PAIN

Another grimace scale has been recently published by the NC3Rs to help in the determination of distress and pain. In this case the focus is on rabbits.

Please check this link for further information: https://www.nc3rs.org.uk/rabbit-grimace-scale. Also note that posters will be displayed in the units as a reminder.
