Brown rats are often viewed purely as pests but are sentient animals capable of suffering. Humane pest management that minimises suffering is an ethical requirement.
Rats killed by anticoagulant rodenticides experience prolonged suffering. Children rats separated from mothers by trapping face starvation. While rat population management is sometimes necessary for human health and safety, methods should minimise suffering. Exclusion and snap trapping cause less prolonged suffering than anticoagulants.
