Pet rat names: small animals, big characters
Pet rats, often called fancy rats, are clever, affectionate and quick to learn their names. Many owners find their rats come running when they say the name, especially at treat time. That makes the choice matter more than it does for a fish or a lizard: you will use it every day, and the animal will actually respond.
Rats are social, and most owners keep at least two, so you will probably be naming a small gang. That is where the fun is. A pair of rats can share a food pairing, a set of old-fashioned names, or a joke. Cheese is the traditional joke, since the stereotype is so strong that Gouda and Brie sound like rat names before you have met the rat. The old-fashioned human names, like Winston, Ophelia and Barnaby, exploit the opposite idea: a tiny animal with a very dignified label.
Color and coat help too. Fancy rats come in hooded, berkshire, dumbo-eared and hairless varieties, and the markings suggest names: Pepper for a black hooded rat, Cashew for a fawn, Pip for the smallest of a litter.
Naming a pair or a group
Because rats live in groups, naming them together is a game. Pick a theme, such as cheeses, breakfast foods, poets or gemstones, and use it for every rat that joins the household. If you want the names to read as a set on a cage tag, filter by first letter and choose names that start with the same sound.
Rats live only two to three years, which is short, and the good news is that a short life makes it easier to reuse a theme. Many owners keep a long-running list of names and pick the next one from it. If you are naming a rat for a child, or as a first pet, choose a name that is easy to say and easy to spell.

Tips for naming your rats
- Choose names that sound different. Rats learn sounds, and Pepper and Pip may both come running when you say only one of them.
- Pick a theme that can grow. Cheeses, nuts, breakfast foods and Victorian names all give you a long list for future rats.
- Say the name in a happy voice. Rats respond to tone, so a name that is easy to say cheerfully gets a faster reaction.
- Plan for at least two. Since rats do best in company, choose a matching pair or set from the start.
- Give a shy rat a short name and use it with treats. A one-syllable name like Pip or Fig is quick to learn.
