Laboratory animals suffer great pain and distress
By law, researchers must work to minimise the suffering of animals in laboratories. This might be by using analgesia or anaesthesia to alleviate pain during or after a procedure, or it could be providing enrichment for animals in order to encourage mental stimulation and prevent boredom. 98% of procedures are classified as sub-threshold, mild or moderate.
It is in researchers’ interests to make sure animals suffer as little as possible; stressed animals are less likely to produce reliable results. All animal research must pass an ethical evaluation which weighs up its pros and cons and decides whether it is justified. The research then has to be approved by Home Office Inspectors, who are all doctors or vets and who ensure that high welfare standards are applied.
