Love them or hate them, mice are quite common in nature. In fact, there are over 1,100 species worldwide. Of those, 200 call North America home. Many of these have adapted to living among humans and may even be nesting somewhere in your home.

Don’t worry, these critters are far less likely to be hanging with you in your living room than a basement or attic. In fact, most mice do their best to avoid people unless there’s no alternative source of food, warmth, and shelter.

However, when they do move in, knowing the particular species of mouse can help you figure out what attracted them and what (if any) health concerns they’re bringing with them.

Note that we will be covering species found primarily in the US here, as an international list would require a small book.

Aw, Rats! Is it a Mouse or Not?

Mouse vs Rat

mouse vs rat

The only actual difference between rats and mice is the size. Members of the superfamily Muroidea that exceed a certain size are referred to as rats, while smaller species are referred to as mice. This means the terms are somewhat interchangeable. However, all members of the genus Mus are considered to be mice.

Types of Mice

#1 – Coarse-Furred Pocket Mouse (Chaetodipus)

These critters have tails generally between 4 and 4.75 inches long, often with crests and bodies ranging from 3 to 3.75 inches in length. Their elongated, narrow hind feet have bare soles and allow them to jump longer distances.

Native to desert climates, they tend to spend the winter hiding in their burrows and are excellent diggers. Pocket mice prefer rocky to sandy soil.

Coarse-Furred Pocket Mouse Breeds and Habitat:

  • Bailey’s Pocket Mouse (Chaetodipus baileyi): Southern Arizona and Southwestern New Mexico to Northwestern Mexico
  • Baja Pocket Mouse (Chaetodipus rudinoris): Southeastern California to Northwestern Mexico

  • San Diego Pocket Mouse (Chaetodipus fallax): East California to Western Utah and Northwest Arizona
  • Spiny Pocket Mouse (Chaetodipus spinatus): Southern California

#2 – Deer Mouse (Peromuycus)

Very similar in size and shape to the common house mouse, deer mice are a little larger and strictly nocturnal. Their large eyes and ears are designed to give them superior sensitivity in low light conditions. They don’t like clement weather and will normally hide in their nests when a storm approaches.

Average body lengths for deer mice and their subspecies range from 2.75 to 3.75 inches in body length with tails roughly the same length or slightly closer to 3 inches. The biggest exception to this is the pinion mouse, whose body and tail are each an impressive 4 to 4.75 long.

The tails are generally bicolored with light hair with the exception of the deer mouse whose tail has heavy fur. Some species also sport a tuft on the tip.

#6 – House Mouse (Mus musculus)

Sometimes referred to as true mice, the house mouse gets its name because it’s most often found cohabiting with humans. In fact, it’s actually the second most common mammal in the world after Homo sapien.

House mice are infamous for leaving women on chairs and brown cupcake sprinkles all over the countertops. This type is often responsible for that dead mouse smell in the garage. However, despite their shy nature, these little guys can be quite friendly and tend to make great pets.

One subspecies, Mus musculus Disnicus, is a rare, highly developed breed that tends to walk on its hind legs and averages approximately 2 feet, 3 inches high and 23 to 30 pounds. The breed was first discovered in 1928. There are only a handful of known examples of this curious subspecies, however they are well cared for and at low risk of extinction.

#7 – Jumping Mouse (Dipodidae and Zapus)
