1. The psychophysical spectral sensitivity of cats was assessed using a two‐choice visual discrimination task by determining increment thresholds and critical flicker frequency on white and chromatic backgrounds. 2. For large increments, on 0.0, 0.3 and 3.0 cd/m2 white backgrounds, the cats were most sensitive to 497 nm indicating that these backgrounds are scotopic. On 30 and 300 cd/m2 white backgrounds, the cats were most sensitive to about 454 and 561 nm indicating that these backgrounds are photopic. Sensitivity to intermediate wave‐lengths indicated independent action of 'blue' and 'green' cones. 3. For large increments, thresholds on photopic yellow and magenta backgrounds indicated the additive influence of 'blue' and 'green' cones. 4. Spectral sensitivity functions obtained with a critical flicker frequency criterion of 10 Hz on a 30 cd/m2 white background reflected only the activity of the 'green' cone while at 20 Hz the function reflected an additive contribution of both 'blue' and 'green' cones. 5. For small increments, on a 30 cd/m2 white or 96 cd/m2 orange background, sensitivity reflected only the activity of the 'green' cone. 6. The cat's photopic spectral sensitivity is influenced by the psychophysical test upon which it is based in a manner that is similar to what has been found for other vertebrates. No evidence was found for a 500 nm mechanism active at photopic levels.
