Listen. Unlike cats and dogs, whose whiskers are made of hair, catfish have special whisker-like feelers made of skin. These sensitive feelers are called â barbels .. Each barbel is loaded with tiny taste buds and special olfactory sensors to help the fish smell.arbels help the fish search out food using their senses of touch and taste. Though it may seem obvious how the catfish got its name, these barbel whiskers are not the only reason. When caught, catfish make a noise that sounds a bit like a cat purring.
On the muzzle, there are four rows of whiskers on each side. The top two rows can move independently from the bottom two rows. The whiskers above the eyes help when the cat is hunting in grass or bushy areas. They trigger a protective eye blink if thereâs a branch or some brush that might get into the catâs eyes. The whiskers also help during contact with other animals (including us) and if touched, they cause an eye blink.
