The cats did not lick at spouts containing QHCl significantly less often than they did at spouts containing water at any of the tested concentrations (Fig. 1). Thus, no significant aversion nor preference for QHCl was found in this experiment. The cats both licked at spouts containing QHCl as well as spouts containing water to similar extent throughout the experiment. A small increase in registered number of licks for both QHCl and water was observed at 0.5 µM QHCl but there was still no significant difference between the two.

At the highest tested concentration of QHCl, 50 µM, the cats were observed to perform tongue protrusion gapes significantly more often when located close to a spout containing QHCl compared to water.
