The painted spiny pocket mouse (Heteromys pictus) is a type of rodent that belongs to the Heteromyidae family. These small mammals live in Mexico and the northern part of Guatemala. It used to be grouped with other mice in the Liomys genus. However, scientists later found that Liomys wasn't a natural group, so the painted spiny pocket mouse was moved into the Heteromys genus.

Physical Description
The painted spiny pocket mouse is a medium-sized rodent. Its head and body grow to about 12 cm (5 inches) long. Its tail is usually about the same length as its body. Male mice are often a little bigger than females.
Their fur is special because it has a mix of stiff spines and soft, thin hairs. The spines are the most noticeable part of their coat. The fur on their head and back is reddish-brown. Their belly is white. A line of dark or light yellow-brown fur separates the colors on their back and belly. Young pocket mice have gray fur that is mostly soft hairs.
Where They Live and Their Home
The painted spiny pocket mouse can be found in Mexico and Guatemala. They live in areas up to 1,000 meters (about 3,300 feet) high. Their range includes western Mexico, from the state of Sonora down to Chiapas, and also the eastern state of Veracruz. They also live in the very northwestern tip of Guatemala.
These mice typically live in dry forests where trees lose their leaves, or in bushy areas. They often stay near streams in dry places, especially where there are cacti and acacia plants. When their living areas overlap with the Mexican spiny pocket mouse (Heteromys irroratus), the painted spiny pocket mouse prefers wetter, lower places.
Behavior and Daily Life
The painted spiny pocket mouse is active at night, which means it is nocturnal. These mice are usually solitary and live alone. They only come together to breed.
They live in burrows underground. While in their burrows, they do things like taking sand baths to clean their fur. They also collect seeds using their cheek pouches, which are like little pockets inside their cheeks. They store this food for later, a behavior called caching. They also spend time scratching and cleaning their fur.
Their main diet includes seeds, especially larger ones. They also eat green plants and small invertebrates. These small creatures can include spiders, moths, crickets, and beetles.
Reproduction
Female painted spiny pocket mice usually have litters of two to six babies. The babies develop inside the mother for about 25 days before they are born. The young mice might stay together for one to two months. However, they separate when they start to become aggressive towards each other.
Conservation Status
The painted spiny pocket mouse lives across a wide area and is common in many parts of its range. The IUCN (International Union for Conservation of Nature) lists this species as being of "least concern". This means they are not currently considered to be in danger of extinction. Even though their numbers are slowly decreasing because forests are being cleared, they are not declining fast enough to be listed in a more threatened category.
