The law defines the levels of severity animals experience as:

1. Subthreshold: where the animals do not suffer from an intervention.

2. Mild: causes short-term mild pain, suffering or distress. Breeding and behavioural assessments qualified in this category.

3. Moderate: causes short-term moderate pain, suffering or distress or long-lasting mild pain, suffering or distress.

E.g. administration of substances, breeding GM animals or surgical procedure with recovery.

4. Severe: animals are likely to experience severe pain, suffering or distress, or long-lasting moderate pain, suffering or distress.

This section includes the animals which may have unexpectedly died.

5. Non recovery. The animal is placed under general anaesthetic before the start of the procedure, and is humanely killed without ever regaining consciousness.
