许多猫视网膜神经节细胞(X、Y和W型)有来自三个独立视锥系统的输入。那些峰值灵敏度在450纳米和555纳米的已经被展示出来了。峰值灵敏度为500纳米的伽马最大锥体可以通过光谱敏感度与其他锥体区分开来，也可以通过感受场差异(高于杆饱和水平)和暗适应曲线中的锥杆断裂来区分。猫的三锥体视网膜与恒河猴黄斑外视网膜的相似性表明，猫可能具有明视三色视觉。
Many cat retinal ganglion cells (types X, Y, and W) have inputs from three separate cone systems. Those with peak sensitivities at 450 and 555 nanometers have been previously shown. A gamma max cone with a peak sensitivity of 500 nanometers can be differentiated from other cones by spectral sensitivity and from rods by receptive field differences, functioning above rod saturation levels, and by cone-rod breaks in the dark-adaptation curves. The similarity of the three-cone cat retina to the extramacular retina of the rhesus monkeys suggests that the cat may have photopic trichromatic vision.
