5 SENSES:

All of the tigers senses are the same as humans (sight, smell, hearing, touch, taste). In their eyes, there are more rods and less cones. Rods deal with visual perception of shapes and cones are responsible for color recognition. Less cones is not a problem for tigers however as they have a structure called the tapetum lucidum which enables them to have heightened vision in the dark and primarily at night. Along with this they have a line of nerve cells  toward the middle of their eye that grants them better peripheral vision. 

 

Tigers use their whiskers as a large part of their sense of touch. There are 5 different types that help the tiger detect sensory information by blood displacement via contact with the root of the whisker. The sensory nerves then alert the brain to discern this sensation. The neurons are extremely sensitive and recognize any change immediately. The 5 different types of whiskers that are scattered across their bodies are cheek, mystacial, carpal, tylotrich, and facial. 

 

Its hearing is more heightened than a humans and can hear more than twice the amount of high frequency noises.

 

Odor detecting cells cover their nose and send signals to the olfactory region of the brain to identify smells. 

 

Their limited amount of tastebuds do not affect their way of life since taste is not as important to them. There is a strategy that tigers use combining their taste and smell senses via the vomernasal organ used for marking territory and intraspecific communication.
