Whiskers are an essential part of an animal's anatomy as they provide them with sensory information about their surroundings. However, some animals are naturally more whiskerless than others. Antonyms for the word "more whiskerless" include "bearded," "hairy," "shaggy," "furry," and "bristly." These words describe animals with long, thick, and abundant hair or fur, including cats, dogs, bears, and many others. While being "more whiskerless" may be an advantageous trait for some animals, having more hair or fur can provide insulation, camouflage, and protection from predators. So, depending on the environment and the animal's lifestyle, being "bearded" or "hairy" can be the better option.
