Levels of Suffering
Articles explain how animal welfare is measured and categorised during testing procedures. Topics cover assessment methods and the four official severity classifications.
Animal Suffering Categories: Mild
UK animal testing in the mild category covers basic procedures like blood samples and minor biopsies designed to minimise animal suffering.
Animal Suffering Categories: Moderate
UK animal testing regulations classify over half of experiments as moderate suffering, with public opposition rising sharply as pain levels increase.
Animal Suffering Categories: Substantial
Animal testing in the UK is categorised by suffering levels, with the substantial category covering about 2 percent of tests but involving significant.
Animal Suffering Categories: Unclassified
UK animal testing rules classify projects by suffering levels, with unclassified meaning animals are killed under anaesthetic without waking.
Assessing Animal Suffering
The UK uses a four-point scale to measure animal suffering in research, from mild procedures like blood tests to substantial interventions.
