White-throated Woodrat (IMAGE) University of Utah Caption A white-throated woodrat carries a sprig of toxic juniper as it runs among rocks at night. This rat species normally eats several toxic plant species in amounts too small to cause poisoning. University of Utah researchers found that when the white-throated woodrat is given a diet with too much of one toxic plant, juniper, it limits its food intake and drinks more water so it doesn't become ill.
