Cats use their whiskers, also known as vibrissae, to sense and navigate their surroundings by detecting changes in their environment. Whiskers are highly sensitive tactile hairs that can detect even the slightest movements and changes in the air. This helps cats to determine the size, shape, and texture of objects around them, as well as to gauge distances and navigate in low-light conditions. Whiskers also provide cats with information about the space around them, helping them to avoid obstacles and hunt prey effectively. If a cat's whiskers are damaged or trimmed, they may have difficulty navigating and may become disoriented.
