Figure 3.

Mice prefer demonstrated food containing warfarin to novel food without the rodenticide. C57BL/6J mice (n = 10) were demonstrated a food odor paired with 50 nM UG. On Day 1, mice preferred food containing the demonstrated over food with a novel odor, although both foods contained warfarin (0.025%). On Day 2, these mice continued to prefer food containing both the demonstrated odor and warfarin even though the other food choice contained a novel odor but no warfarin. One-Way ANOVA [F_{(1, 19)} = 10.1, P < 0.005], followed by Tukeys post-hoc test (^*P < 0.01). Dashed lines, no preference. Error bars, standard error of the mean.
