Porcupines are mammals from "The Cat in the Hat Knows a Lot About That".
Porcupines are rodents with spiky quills, which are very sharp modified hairs. The rodents can weigh from 12-35 pounds.
Porcupines are herbivores, which means they eat fruits and grass. They mainly come out at night, which means they're nocturnal. Porcupine needles can pierce the flesh of an attacker, and these wounds could even be fatal. Only New World porcupines that come from North America and South America can climb trees. Porcupines can be considered pests and are often hunted for meat, but they're not endangered.
