What happens if a human eat cat whiskers?

If a human eats cat whiskers, they are unlikely to experience serious harm, as whiskers are made of keratin, the same protein that forms human hair and nails. However, consuming them is not advisable, as they can be indigestible and may cause discomfort or gastrointestinal issues. Additionally, there is no nutritional benefit to eating whiskers, so it's best to avoid them entirely.
