Whiskers are a sophisticated sensory mechanism. How do bald felines maintain their balance without whiskers?
Sphynxes and other hairless cats can balance without whiskers because whiskers do not regulate balance. Whiskers, however, play a role in several related functions, such as depth perception, proprioception, and even night vision. Bald cats may lack precision and agility in complex situations.
Hairless cats have adapted to living with fine whiskers or without any whiskers at all. However, having few or no whiskers makes it more challenging for cats to orient themselves in unfamiliar environments, especially outside.
Do Sphynxes and Other Hairless Cats Have Whiskers?
Most furry cats have 24 vibrissae, or whiskers, on their faces. They also have finer vibrissae on their paws and chins.
Some Sphynxes and other hairless cats have fine short whiskers. Their whiskers might be brittle and break easily.
If a bald cat has any whiskers, they have a similar function. Many bald cats do not have any vibrissae at all.
How Do Cats Balance?
Like all other mammals, the cat’s ability to balance is primarily regulated by its inner ear, which connects the middle and external ears.
The cerebellum is the structure in the brain that ultimately is the control center of balance and movement.
The tail helps the cat evaluate their surroundings and sense their position relative to other objects.
Do Whiskers Impact Cats’ Balance?
Whiskers do not contribute to balance, so a hairless and whiskerless cat can walk and jump without losing balance.
However, whiskers have related functions that affect the ability to balance in complex situations and navigate the surroundings.
Why Do Cats Need Whiskers? How Do Whiskers Affect Functions Related to Balance?
Each vibrissa performs a sensory function for felines. For that reason, whiskers and eyebrows should never be trimmed.
Cats can balance without them but the perception of depth and proprioception, or the ability to sense their movement and location, are impaired without whiskers and eyebrows.
Although an indoor cat adapts to living without whiskers, all the associated limitations with navigating the environment are a major challenge for outdoor cats.
– Proprioceptor
Cats can sense the vibration from their movement or the objects around them to feel where they are about their surroundings. This is one of the mechanisms that helps these animals maintain precision and grace and survive in a world that requires a quick reaction to any movement around them.
Amazingly, each vibrissa has a proprioceptor – a sensory organ – that perceives information from the environment and delivers it to its area in the brain.
– Night Vision Aid
Whiskers are particularly important at night. Cats can see much better than us in the dark, of course, but their eyes do not perceive depth quite as well without light. Whiskers contribute to the animal’s ability to be aware of the surroundings in the dark.
– Depth Perception
Whiskers also allow the animals to gauge the depth and size of a tight space, in the light and the dark. They help to estimate the surroundings via tactile contact and perceiving vibration.
– Communication
In addition, cats communicate their state with their whiskers, among other body language ways. Their whiskers look relaxed when the cat is calm and sleepy. Any arousal causes the animal’s whiskers to face forward to communicate a range of states, from playfulness to defensiveness.
The VCA Hospital website has a detailed article on the function of cat whiskers.
How Do Sphynx Cats Function Without Whiskers?
For a cat used to living with a full set of whiskers and eyebrows, losing several whiskers affects orientation and perception until the whiskers grow back. It is not the same for cats who never had whiskers because they adapt to living without them.
Sphynxes and other bald cats rely on perceiving the world through other sensory organs. So, they function fine without vibrissae and can certainly balance without them. However, hairless cats still miss out on the functions of whiskers that other sensory organs cannot replicate.
Unlike furry cats, bald cats do not have excellent depth perception and do not react as quickly when they fall because their proprioception is less effective.
Sphynxes and other hairless felines are less adapted to functioning in the dark. Even their daytime vision may be affected since cats use whiskers to study objects near them.
To Sum Up
Having no or having few vibrissae is a characteristic that makes it challenging for bald cats to survive outdoors. Having no fur to insulate and protect them is another, more obvious, feature that makes these pets more vulnerable outside. Sphynxes and other bald feline beauties are not equipped to be outdoor animals.
Living at home, with all the protections available from the great outdoors, enables them to function just fine without whiskers.
