Rats are social animals and having the companionship of a littermate is good for them, we think. It doesn't take much handling to get them used to being touched. Rats are the furtive invaders who hide in the dark, dank spaces of our buildings and towns, emerging en masse after dark to feed on garbage and food scraps. They can carry disease, either directly or via the insects that feed on them (such as the fleas whose bite spread the bubonic plague). Rats are considerably smaller than dogs but are at least as capable of thinking about things and figuring them out! And, while rats are much smaller than elephants, they have excellent memories.

Rats are normally lifted by grasping the whole body with the palm over the back, with forefinger behind the head and the thumb and second finger under opposite axilla. This extends the rat's forelimbs so that they may be controlled (future picture). Rats are indigenous to almost all areas affected by land mines, and are thus less prone to tropical diseases than non-native mine detection dogs. In addition, the cost of training and upkeep is less for rats than dogs. Rats are absolutely fascinating (and fantastic!). I've adopted many throughout the years as companions.

Rats are carriers of many different diseases, they contaminate food, and sometimes bite. Rats are primarily nocturnal. Rats are clean, intelligent, affectionate animals which bond to their human companions in much the same way that dogs do, and with the right care should provide a comparable level of companionship. They are the same species as the wild brown rat, Rattus norvegicus , but have been selectively bred for looks and temperament for at least the last century and are now quite different in temperament from their ancestors. Rats are social animals that are happiest when kept as same sex pairs who are familiar with each other. You may also house together a pair that has been spayed and neutered.

Rats are found worldwide in almost every type of environment. They are related to mice , but are usually larger. Rats are and always have been a problem underground, and with trash collection posing problems for the MTA, rats live the good life. Corrigan claimed that trash storage areas where garbage may site for a few days are breeding grounds for the rodents. Rats are also quite clean, and can even be litter trained if you start when they're little.

Rats are very intelligent and can be taught simple tricks, such as stay and sit and will often learn their name. They can also be litter box trained. Rats are wary animals and can be frightened easily by unfamiliar sounds or sounds coming from new locations. Most rodents, however, can quickly become accustomed to new sounds heard repeatedly. Rats are expert climbers, so they could be getting in under the eaves of your roof.

Rats are omnivores (and not very picky ones). They have terrible vision, and they’re colorblind, so they rely on their fine sense of smell and whiskers for touch. Rats are typically distinguished from mice by their size; rats are generally large muroid rodents, while mice are generally small muroid rodents. The muroid family is very large and complex, and the common terms rat and mouse are not taxonomically specific. Rats are known to grind their teeth so as to sharpen their incisors against one another. All rodents need to gnaw and chew frequently to keep their incisors from overgrowing.

Rats are the most beloved animal of most toxicologists, you see. More compounds have gone through rat tox than any other species, so there's a large body of experience out there.

TELLTAIL SIGNS OF RATS 

Rats constantly leave droppings in areas that they frequent. Fresh droppings are dark in color and soft in texture. After 3 days, they harden and lose their dark color.

Rats urinate in areas that they frequent. Since urine gives off a fluorescent glow under ultraviolet light, a blacklight can be a useful tool for locating areas of rat contamination.

Rats always travel the same runways and leave smudge marks- a buildup of dirt and oil from their fur-along walls, pipes, gnawed openings and particularly and rafters for roof rats.

Rats keep indoor runways, or well-used paths, free of cobwebs, debris, and dust. Norway rats’ runways are usually well-defined paths at floor level next to walls and other vertical surfaces. Roof rats’ runways are above on rafters, pipes, etc.

Outside, roof and Norway rats’ runways appear as narrow paths through vegetation.

Rats are noisy and you can hear them when climbing, gnawing, clawing, moving and chattering to each other.

Footprints and tail drags can be seen in dusty locations.

Gnaw marks are a sure sign of rats. Their teeth grow continuously and they must gnaw on everything in order to survive.

Rats produce a distinctive musky odor.

Norway rats usually burrow, but nests under concrete slabs, in rag piles or in lumber piles are not unusual.

Roof rats’ nests are usually up high and are often difficult to find. Sometimes nests are similar to tree squirrels’ nests, consisting of leaves, twigs and vines. 

Light Infestation (less than 20)

A few fresh droppings found in out of the way areas. Fewer than 30 droppings can be found in any one place, and the number of droppings is less than 6. 

Medium Infestation (20 to 50)

Fresh droppings seen in 20 to 30 locations. Old droppings and fresh gnawing found. One or more rats seen at night; usually no rats observed during the day. 

Heavy Infestation (more than 50)

Fresh droppings seen in numerous locations along with old droppings of various sizes, indicating an increasing population. Fresh track, gnawing, smudge marks and 3 or more rats noticed at night or rats seen during the day. 

Rodent Removal / Rat Trapping / Diseases

Humans and our pets are at risk whenever we breathe uncirculated air that contains dust particles from rodent droppings or areas with a heavy presence of urine. It is very common in attics, basements, storage rooms, and garages to find dried feces and rodent urine, which may contain germs that can cause disease. Human influenza pandemics have happened several times in the 20th century, including 1918, 1957, and 1968.

Symptoms do not manifest for two to four weeks after exposure to the organism, and the wound through which it entered exhibits slow healing and marked inflammation . The fever lasts longer and is recurring, for months in some cases. Symptoms include poor body condition, rough hair coat, reduced growth rate and rectal prolapse. Infection with pinworms has a negative impact on gastrointestinal, growth, behavioral and immunology studies.

Generally, these lines are not transgenic, however, because the easy techniques of genetic transformation that work in mice do not work for rats. This has disadvantaged many investigators, who regard many aspects of behavior and physiology in rats as more relevant to humans and easier to observe than in mice, but who wish to trace their observations to underlying genes. Generally, if a rodent can squeeze it's head through an opening, (most rodents heads are the size of a quarter or smaller), it will eventually get through. This is why your strategy for rat or mice control always starts on the outside of the structure. Generally it is best to not use beddings with additives. Chlorophyll bedding has chlorophyll added to give it a clean, fresh aroma.

Genetically mice are classified as random-bred, inbred, or F1 hybrids. Generally, if a rodent can squeeze it's head through an opening, (most rodents heads are the size of a quarter or smaller), it will eventually get through. Generally, rats are more harmful to humans than mice.

Gene knockouts have proven to be revolutionary in understanding gene function, but have been mostly restricted to mice and simpler model organisms.

Mice as laboratory animals. Rats as laboratory animals. Mice also are used to test new procedures and drugs for safety, as required by an array of federal regulations. Another primary use of mice is for the production of biological reagents, such as monoclonal antibodies and vaccines. Mice and rats with this problem must have their overgrown incisors trimmed periodically by an experienced veterinarian or veterinary technician.

Mice and rats cannot be acknowledged as useful pets and live within the community . Bacteria, vermin and pests cannot be tolerated . Mice kept on pine shavings for 8 months developed abnormally enlarged livers. This same study found that mice housed on pine shavings also had a decrease in reproduction rate.
