15 Food and Digestion The crested porcupine is for the most part herbivorous, eating roots, bulbs, crops. But occasionally they do consume insects, small vertebrates and carrion. In order to ingest calcium and sharpen incisors they often gnaw on bones. These animals often travel long distances looking for food. They have high crowned teeth that grind plant cells which are digested in the stomach and the undigested fibers are retained in an enlarged appendix and anterior large intestine where they are broken down by microorganisms (Wikipedia). Reproduction Most of what is known about reproduction in the crested porcupine comes from individuals in captivity. Usually female crested porcupines have one litter every year. One or two very well developed young are born in a chamber within the burrow that is usually lined with grass, but only after a 66 day gestation period, on average. The young weigh about 1000 g at birth, which is about five percent of the mother’s weight. They leave the den after one week. At this time the spines begin to harden. Crested porcupines reach adult weight at one to two years and are often sexually mature just before then (Wikipedia).
