Famously, birds of prey feed on mice and rats. Raptors, including hawks, owls, eagles and falcons, are common predators. Red tail hawks, found across most of North America, and American kestrels, the smallest falcon in North America, will hunt rats by day.
The northern spotted owl is the main predator of the rat. It lives in the forests of North America and preys on a variety of small animals, including rats. The owl has excellent hearing and can easily find and capture it. This predator will also eat the young rats, which helps to keep the rat population under control.
Rats are afraid of human activity, mostly because humans are so much larger than they are. Rats also fear predators such as hawks, eagles, and other birds of prey. Other animals that rats are afraid of include your cat as well as rat terriers and other dogs that hunt rodents.

It turns out that baking soda catalyzes some form of reaction inside the rat's stomach. Baking soda combines with the stomach acids to produce carbon dioxide gas which rats are unable to tolerate. In turn, it builds up within their system and eventually causes internal blockage and rupture.
Failing to report a rat infestation is not wise – they do not disappear of their own accord and they will likely spread.
These experiments establish that rats can communicate fear and induce specific odor fear learning via pheromone information.
“An adult rat is a formidable opponent for a cat, so most pet cats won't go near them — only cats that were trained by their mothers how to deal with a rat,” he says.

Rats and mice are nocturnal with most activity taking place between approximately one half hour after sunset to about one half hour before sunrise.
In autumn and sometimes even late summer, rats become more active. In this time of high activity, they gather and store as much food as they can in their burrows for the upcoming winter. Though they do not hibernate, they stockpile on food to reduce the need to leave the warmth of their burrows.
And they can, in fact, rise up from the sewers. VIDEO: WATCH OUT! A rat's super swimming ability and flexibility enable it to make its way easily from the city streets to your toilet. See how they do it.
