Whisker question?

It's absolutely normal and nothing to be concerned of. Whiskers are very important to a cat because they act as feelers which enable a cat to learn whether a given opening is wide enough to admit the cat, but they also operate as air current detectors, which greatly enhance a cat's ability to hunt at night. Cats are equip with different kinds of whiskers - "eye-whiskers", "chin-whiskers", or "leg-whiskers" and in your cat's case, ear''s whiskers!
