10 Rat Facts
If a rat is trapped and released it can move up to four miles from the release point.
A rat burrow can be three meters deep but is rarely more than 0.5 meters deep.
Brown rats show a tendency to be negative geotaxis which means they prefer to move downwards as opposed to upwards.
Black rats are superior climbers and can climb any slightly roughed surface up or down.
Brown rats can jump vertically more than 77cm and 120cm horizontally.
At one time 11-31% of all female rats are pregnant.
Patterns of movement become so engrained in rats that when they get used to moving around an obstacle, if the obstacle is removed they will continue to move around it. Thus the correct siting of trap means they do not have to be baited but it is imperative they are placed directly on the run.
Female rats can distinguish the sex of their offspring by smell.
Rodents can live and breed in cold stores and have been known to nest in the fat layer of carcasses.
Rats eat up to 10% of their body weight a day and cannot live without access to water.
