Fancy Rat - Rex
Other name: Rattus, Norway Rat
Scientific name: Rattus norvegicus
Country / Place of origin: Europe
History:
Pet rats are descended from their wild cousins, the Brown / Norway Rat (Rattus norvegicus). Rats were prolific in England in the 1700s and were mentioned in American books in the 1920s. The Mouse and Rat Breeders Association was formed in 1978, while the American Fancy Rat and Mouse Association was established in 1983.
Appearance: Fancy Rats average 14 to 18 inches (35 - 46 cm.) in length including the tail. They have long lean bodies with large eyes and ears, and a long tapering tail. The head is also long and triangular with a somewhat pointed snout.
The The American Fancy Rat and Mouse Association (AFRMA) classifies fancy rats by variety and sections. The Standard Variety of Fancy Rat has a short, dense fur that is smooth and with a natural glossy shine. Males tend to have a longer and less smooth coat.
Each Fancy Rat Variety is divided into Sections defined by colors and body markings. The American Fancy Rat and Mouse Association (AFRMA) lists 33 distinct colors. The six recognized Sections are: Self, AOC (Any Other Color), AOCP (Any Other Color Pattern), Silvered, Marked, and Odd Eye.
Within the Marked Section of Fancy Rats, the recognized patterns are Bareback, Berkshire, Capped, Dalmatian, Essex, English Irish, Irish, Hooded, Masked, and Variegated.
Average weight: 300 - 800 grams
Lifespan: 2 - 3 years
Grooming: Rats normally do not require grooming by their owners. They self-groom areas of the body by scratching with their claws or nibbling with their teeth. They “wash” themselves by licking their fur or spreading saliva on their paws and rubbing them against their faces or fur. Sometimes they groom each other as part of their social activities, as a sign of friendship, or to convey dominance.
In cases when the pet rat is soiled or extremely dirty, a gentle bath may be required, using a mild shampoo recommended for kittens.
Diet: The recommended food for Fancy Rats are called “lab blocks” or laboratory pellets specifically formulated to give rats and other pet rodents the balanced nutrition they require as well as the gnawing experience that keeps their teeth from growing too long. Some dry mixes are good as well, though they allow the rats to potentially become picky eaters. Natural foods like fruits, vegetables, nuts, seeds, pasta, grain mixes, low-sugar cereals, plain popcorn, and wheat bread are well accepted and should be given as frequent treats.
Fresh water should always be available and refreshed and the bottle cleaned daily. Water is best provided in hanging gravity bottle feeders installed with gnaw-proof attachments.
Housing: Fancy Rats are best housed in a medium to large wire cage or aquarium with a screen lid. The enclosure should be large enough to allow the rats to explore and exercise.
Rat cages should be provided with non-toxic bedding like torn unprinted newsprint, tissue paper, or clean hay (though hay may bring mites into the habitat). Hide-aways, hammocks or sleeping boxes should also be available. Exercise furnishings like large PVC pipes, cardboard or wooden boxes, shelves and ledges, mazes, and a large wheel (which must be safe for long-tailed rodents), are recommended. Gnawing toys like wood blocks, rawhide, and soup bones help the rats pare down their fast-growing teeth.
Fancy Rats are social animals and best housed in same-sex pairs or groups, unless breeding is intended. Even in case of breeding, between litters, both the male and female should be housed in a minimum of same-sex pairs. Only in very rare cases is it required for certain rats to spend their life alone. A rat keeper should only come to this conclusion after having tried to pair up said rat with several different potential cage-mates. Rats should not be housed with other species of small mammals.
Health issues: Fancy Rats are hardy but can also be prone to ailments like: skin parasites (fleas, ticks, lice, and mites); respiratory conditions such as colds and pneumonia; tumors; constipation (not enough greens); diarrhea (too much fruits and vegetables); occlusion (from overgrown teeth); and obesity (leading to cardiovascular diseases, diabetes, and arthritis). Females are highly prone to developing mammary tumors from about 1.5yrs old. Most of these tumors are benign and can be easily removed by an experienced small animal / exotics vet. Ensuring a healthy environment and proper diet prevents most of these ailments. Persistent problems are best handled by veterinarians.
Behavior / Temperament / Activity level: Fancy Rats are naturally inquisitive and active. They can be good pets, especially for children, if tamed through gentle handling and daily interaction. They can be taught simple tricks through repetition and rewards.
