Rabbits
respiratory distress, overdose, seizure
Pre-established criteria for euthanasia of rabbits included the presence of any seizure, severe respiratory distress, and unresponsiveness to touch or external stimuli (moribund). If a drop in hematocrit below 20% was observed, affected rabbits were closely monitored and evaluated by a veterinarian. For euthanasia, rabbits were first sedated with acepromazine (1–6 mg/kg) and then given an overdose of an agent containing pentobarbital.
