Pet Rat Facts

  • Average lifespan of a pet rat is two to three years.
  • Most pet rats are actually a type of rat called a Norway rat (Rattus norvegicus). Other names for a Norway rat are common rat, brown rat, street rat, sewer rat, Hanover rat, Norwegian rat, or wharf rat.
  • A Norway rat body is typically nine to eleven inches long with their tail being an additional seven to nine inches long.
  • Rats are nocturnal so they will be most active at night.
  • Male rats are called bucks, females are does, and babies are pups.
  • Rats are social creatures so they do best if kept with another rat (or group of rats).
  • Rats reach puberty very young at six to eight weeks of age. They shouldn't be bred this young though, so make sure males and females are separated before they reach this age.
  • Females go into heat every four or five days (for about 24 hours) once they reach puberty and may seem agitated or restless during this time. This is why it is so easy to breed rats.
  • Rats have a wide range of markings as well as breed varieties (e.g. standard/smooth, rex, hairless, tailless).\
  • As a rule, males are larger, somewhat lazier than females, and have a coarser coat. Females are smaller and tend to be more active and playful than males.

Rats as Pets

Rats are intelligent and social animals that can make wonderful pets. They are also easily tamed so they are especially great for someone who likes to handle their pets.

Pet rats are relatively easy to care for but that doesn't mean they are low maintenance pets. They require a fair amount of attention and exercise time outside of their cages (at least an hour a day is ideal).

Since rats are very social they should never be kept alone. Same sex pairs or groups are ideal and males usually get along fine with other males especially if introduced at a young age or if they are litter mates.

Keeping rats in groups does not make them more difficult to tame if they are handled from a young age so you won't have to worry about creating a bond with your pet, even if you have several of them. Many rat owners love the curiosity of their pets and compare the companionship of a rat to that of a dog.

Where to Get a Pet Rat

A few options exist to you if you are searching for a new pet rat. While the obvious option, a pet store is only a good option for getting a pet rat if the staff is knowledgeable about caring for rats. Look to see if they keep them in appropriate and clean housing with a good diet and handle them regularly. Also, look for stores that house males and females separately to avoid a surprise litter.

Breeders (ratteries) are the best option for finding a well socialized young rat. A good breeder will make sure the babies are socialized and handled from an early age. Also, a breeder is probably your only option if you are looking for a particular coat type or unique color of rat.

Shelters should always be considered if you'd like to rescue a rat in need of a home. Check with local shelters or rat specific rescue groups. Choose a rat with a good temperament but keep in mind that rescued rats may be a little skittish or shy at first but you can usually overcome this shyness with some patience.

Avoid rats that are aggressive though, as this is harder to overcome and most rats are not naturally aggressive.

Choosing a Pet Rat

When choosing a pet rat, try to avoid ones that are panicky when handled, especially if they do not relax quickly. On the opposite end of the spectrum, also avoid those that are overly quiet and calm as they may be ill. Often a good choice is a rat that is curious enough to approach you.

Rats should be alert and active when observed. Their body should be firm and well rounded but younger rats are likely to be on the lean side. The nose, eyes, ears, and rear end should be clean and free from discharge. The coat should be clean and well groomed (healthy rats spend a lot of time grooming). The skin on the ears and tail should be clean and pink, not red or brown, and free of sores, redness, and dandruff.

Lice is common in pet rats so also check behind the ears where there is less fur for nits. Watch the rat's breathing to make sure it is not labored and make sure the rat is not sneezing or having discharge from its nose or eyes (all of these things can be signs of respiratory disease which is fairly common in rats). Watch for drooling or wetness around the mouth which can be a sign of dental problems.

If you are observant in your selection, you'll be quite happy with your new companion and have a couple of years of fun.
