Fancy rat

The fancy rat is the domesticated form of Rattus norvegicus, the brown rat, and the most common species of rat kept as a pet. The name fancy rat derives from the use of the adjective fancy for a hobby, also seen in "animal fancy", a hobby involving the appreciation, promotion, or breeding of pet or domestic animals. The offspring of wild-caught specimens, having become docile after having been bred for many generations, fall under the fancy type.

Life Span 3-8 years
Weight 0.5-2 kg

What to Know Before Buying a Fancy rat

Finding a responsible Fancy rat breeder requires more than browsing classified ads or responding to social media posts. The USDA requires any breeder who sells small mammals commercially — especially those selling online or through third-party dealers — to hold a federal license and submit to regular inspections. A legitimate breeder should be willing to provide their USDA license number, invite you to visit their facility, and show you where the animals are housed and socialized.

Before committing to a purchase, ask the breeder for veterinary health records, vaccination documentation, and any genetic testing results relevant to the Fancy rat. Reputable breeders will also ask you questions in return — about your living situation, experience with animals, and ability to provide long-term care. A breeder who asks no questions and is eager to ship an animal immediately is a significant red flag.

Use the search tool below to check whether any USDA-licensed facilities breeding Fancy rats appear in our database. If they do, review their inspection history carefully. Look for patterns of violations, pay attention to severity levels, and compare their compliance grade with other breeders in the same state. This due diligence takes minutes and can save you from supporting a facility with documented animal welfare problems.
