As mammals, young pocket mice subsist on their motherвЂ™s milk for about 30 days. Newborn Pacific pocket mice are less than one inch in length and one gram in weight. Some females, however, produce two litters per year depending on environmental conditions. Typical females produce one litter annually, sizing from about two to eight pups. Unlike other species of the rodent family, Pacific pocket mice do not reproduce offspring in large quantities or at a fast rate. The gestation period is about 22 to 23 days. The breeding season of Pacific mice is April to July, but can vary depending on temperature, availability of food and water, and the quantity of habitat vegetation. Interestingly, the Pacific pocket mouse has a very high metabolic rate, so it needs a constant supply of food while active. It conserves water, amazingly, by concentrating its urine and reducing evaporation. It has a large mouth pouch where it can temporarily store food for later use. The mouse gathers its food during the night.

Seeds are the main food of the Pacific pocket mouse, but it can also feed on small insects and vegetation. To preserve body heat and food, they hibernate during the winter season. They live in sandy coastal soils, where adequate vegetation is found, and create underground burrows as shelter. Pacific pocket mice are found in California in the United States, and Baja California in Mexico. LetвЂ™s find out the answer to the question, вЂњis the pocket mouse an endangered species?вЂќ Habitat and Diet

To avoid being seen by predators such as feral cats, it mimics the color of soil. The mouseвЂ™s dorsal color is an adaptation for protection from predators. The dorsal side of the mouse is pinkish and brown, while the ventral side is usually white. A mere 4.25 inches to 5.2 inches in length, and 0.25 oz to 0.33 oz in weight, its body is entirely covered by silky fur. The Pacific pocket mouse is one of the smallest and lightest rodent species.
