How many quills does an adult porcupine have?

It's impossible to give an exact number for the amount of quills an adult porcupine has. The number can vary significantly depending on the individual porcupine, its age, and even its health.

However, a general estimate is that an adult porcupine can have anywhere from 30,000 to 50,000 quills.

Keep in mind that these are just estimates, and the actual number could be higher or lower for any given porcupine.
