In the previous paper the writer reported preferences of the domestic cat for Menyanthes trifoliata (Motomura 1966). For the present observation the writer tested the reaction of the cat to other species of the same family Gentianaceae, and found that some of them induced a remarkable preference reaction in the cat. The reaction of the cat to the plant was observed on fresh, half dry, or completely dry, materials. Further, it was noticed that the dry distillate of the plant was more effective in comparison with the plant itself or with water extracts. This shows the effective ingredient is volatile or sublimating one. It was shown that many species of gentianaceous plants contain a substance or substances preferred by the cat. Among 14 species used, Fauria crista-galli and Menyanthes trifoliata showed the strongest effect on the cat. To those plants the cat showed a strong "dancing" reaction. The phenomenon was found in many species of Swertia and Gentiana to a lesser extent.
