Types of Pet Rats (2024)

Pet rats are fun, inquisitive, social, clean, and friendly creatures who can make a great addition to families. Pet rats are also known as fancy rats. Humans selectively breed pet rats for specific characteristics—typically physical or behavioral traits, as well as longevity. Breeders even started showing their pet rats as early as 1901. Through this selective breeding, there are now seven different recognized types of pet rats.

While there are more than 60 types of wild rats, all pet rats come from the same species: Rattus norvegicus. Because all pet rats are R. norvegicus, different types are known as varieties—not breeds. Below are the most common varieties, colors, and markings currently recognized by the American Fancy Rat & Mouse Association (AFRMA).

Pet Rat Varieties

• Standard

  • Standard rats have short, smooth, and glossy hair coats. Male rats may be larger and have coarser hair coats than females. This variety comes in many coat colors and is the closest to the wild brown rat. They have no unusual diet or medical needs.

• Rex

  • Rex rats, similar to other Rex pets (cats, guinea pigs, rabbits), have curly fur with few guard hairs. Their whiskers may even be curly. They may feel wooly, especially male rats. Rex rats may lose hair as they get older. Sometimes this variety is also called a Manx.

• Tailless

  • Tailless rats are quite simply named. While most rats have a tail as long as their body, tailless rats are bred to have no tail whatsoever. These rats may be stockier with a rounded rump than other varieties. Breeding tailless rats can result in physical deformities and medical issues. Specifically, this variety can have hind leg and vestigial tail deformities and bladder or bowel problems. A tailless rat may also be referred to as a Sphinx.

• Hairless

  • Hairless rats are also aptly named. This variety does not have any hair at all, with smooth, imperfection-free skin. They may or may not have whiskers. Hairless rats can easily acquire illness and especially need added warmth. Because they often get sick, this variety may have a shorter life span and some breeders are pushing to limit or stop breeding of this variety altogether.

• Satin

  • Satin rats have long, smooth, silky coats. Their whiskers are long until the very end with a tiny curl. Satin rats may come in many colors and markings.

• Dumbo

  • Dumbo rats are one of the more common varieties. They have larger, low-set ears, conjuring images of the Disney classic elephant character. Some rat fanciers believe dumbo rats are more friendly and may even live longer—however, this has never been scientifically proven.

• Bristle Coat

  • As the name implies, bristle coat rats have coarse coats, like a wire brush. Their fur may even feel crunchy, like the coat of wirehair terriers. Young bristle coats may have curly hair similar to a Rex but will change as they mature. They may have curled tips of their whiskers, like satins.
