Intermittent gnawing activity, paralysis, urine incontinence, convulsions and panting were observed in the gray red-backed voles after consumption of rodenticide pellets weighing 0.167g and containing 1% zinc phosphide. When the voles ate 1.0-2.7 pellets, their haunches were paralyzed 2.2h later at the earliest. They then suffered considerable locomotion ataxia. Death occurred after 4-6h.
