What is a rat’s natural diet? Despite the common thinking, rats, even though invading mostly unsanitary places, have a very sophisticated and “clean” nutritive needs. Their strong natural immune system protects them from contracting any illness, but rats choose mostly natural, fresh and nutritive food. Rats feed depending on the capacity of their environment to produce food. This means that rats might raid dumpsters, farms, sewage pipes and even households.
The types of rat most common in United States are Black Rat (more rare), and the most common Brown (Norwegian rat). Both types have similar nutritive needs, but feed accordingly to environment they live in. In general, rats are omnivores, which means they will eat almost anything. Their diet may vary depending on the location they are inhabiting.
Most rats prefer consuming meat, dairy-based products and vegetables. They tend to avoid fruit and food containing sugar. When it comes to consuming vegetables, Black rat tends to raid fields and frequently eats corn and wheat. This food is also present in the diet of the Brown rat, though this type, as being more widely spread (the species inhabits both America and Europe), doesn’t tend to have a predominant eating preference. Black rat is known for invading farmer’s estates all over the west coast of United States, hunting for birds, and often poultry. When invading households Black rats tend to damage field and kill poultry, as well as smaller farm animals. Brown rat will often hunt as well, and it is known to hunt birds, smaller animals and even fish.
In urban areas, both species of rat will most likely provide themselves with food from garbage sources, like household trash cans and dump yards. They will, however, choose fresh and good-quality food remains. They will most often opt-in to eat dairy products, vegetables, meat and wheat’s. In diet of both of these species, and rats in general, food containing sugar will cause obesity. In the wild, rats will hunt for their own food, and are capable to subdue pray a lot larger than their natural size. They will also eat any other food they can get a hold of.
However, if they are inhabited near people, they will tend to feed on remains of human food. Still, rats will choose good-quality and fresh pieces to snack. The amount of nutrients that rats need on a daily basis is considered to be larger than other animals people keep as pets, so the owners are advised not to feed their rats with cat, dog or hamster good, because it will not be as nutritive as to fulfill the needs of a rat.
