Rats Sense Of Smell

This sense is one of the highly developed senses in rats and mice. They can sense all sorts of different smells which are not noticeable to the human sense of smell. 1% of their total DNA has been assigned to their olfactory receptors. They have another special organ to receive pheromones secreted by them in their urine. These help the other rodents to know about each other’s age and sex. Vomeronasal organ is the name given to it, and it is located just off the nasal cavity. Rats sense of smell is so strong that it is hard for a human being to imagine what sorts of different smell signals a rat’s brain might be receiving at one time. This is one of the main reasons that rats love to live around human habitation.

Sense Of Touch

Rats and mice have a highly developed sense of touch. Unlike humans who can feel things through their fingers, the rats have whiskers on their muzzle and eyebrows which help them to get a clear idea about the environment around them. As these rats and mice are nocturnal and move around at night time in dim lights  their whiskers  constantly vibrate and sense the surroundings. These stiff hairs can help them to sense movements, textures, and vibrations. These rodents depend more on their sense of touch rather than the sense of vision to move around. The bend in the Vickers sends a message to the brain about the possible obstacle in their way. 

There is another adaptive behavior of rats that they tend to move along the junction or vertical walls and floors; this is due to the fact that they want to protect themselves from one side. Thigmotaxis is a name given to this behavior of rats and mice. It is believed that they do this to prevent themselves from predators.

Sense Of Sight

Out of all other senses, this is the less developed sense compared to human senses where rats and mice win over humans in all other senses development but their sense of sight is a blur. They can not see as in-depth and far as humans can. They also can only see green and blue colors and red is the color they can not distinguish. They can detect UV light. Their sense of sight only gives them a rough idea of the shape of the object. Their sense of sight is enough for them to provide the idea of the environment they live in. 

Sense Of Hearing

Rats have excellent hearing capabilities. They can detect up to 900,000 Hz of sound waves. On the contrary humans can only listen up to 200,000 Hz. They can communicate with each other also in ultrasonic waves. They use them to warn their friends and siblings of any potential danger. They can hear A lot more moving waves of sound than us, so they can listen to us coming towards them before we even reach near.

Sense Of Taste

Rats and mice have all sorts of taste buds; they can taste sweet, bitter, sour, salt, and savory flavors. They are omnivores,so they can eat anything which is non-hazardous to them and is edible. Their sense of taste is mainly transferred from the mother, and they can inherit the preferences through their mothers. Yet again, they discover new contrasts of flavors and try different foods all their life.
