PT journal article

AB AIM: To assess the sickness behaviours of possums after eating a lethal dose of potassium cyanide. METHOD: Spontaneous behaviour and the time to loss of physical responses were examined. RESULTS: Cyanide ingestion caused a short-lasting period of mild respiratory stimulation. There was no salivation, retching or vomiting. Convulsions occurred in 73% of the possums. After the ingestion of cyanide, the average time to onset of ataxia was 3 minutes, the average time to overall loss of consciousness was 6.5 minutes, and the time to cessation of breathing was 18 minutes. CONCLUSION: Cyanide is a rapid-acting toxin with few undesirable signs from the welfare perspective.
