Types of rats

Before discussing what rats eat, let’s take a look at some types of rats that exist in the world. Rats belong to the genus Rattus, a division of the Muridae family, which also includes mice. But, ‘‘Where do rats come from?’’ It is believed that the rat species origin dates back to contained Asia, although today, they are distributed throughout almost all of the world (except for Polar regions).

In the past, rats were considered wild animals that made up part of the abundant fauna of fields and vegetation. However, with the growth and evolution of humans and space, these rodents are now abundant in cities as well as fauna. Additionally, rats are also now considered a great companion animal, like mice!

In total, there are more than 20 different types of rat species in the world. The most common rat types include:

Brown rat

Rattus norvegicus is also known as the common rat, sewer rat, Norwegian rat, Parisian rat and/or street rat. The brown rat is considered the most abundant of rat species in urban environments and is characterized for its brown coat, short tail and small ears.

This species is known for being more aggressive than other rat types. In the wild, these rats prefer to live near slopes and rivers, and are also considered excellent swimmers.

Black rat

Rattus rattus, also referred to as a house rat, roof rat or ship rat, is very similar to a mouse but larger. The black rat is characterized for its black fur and distinctively long tail. This rat species prefer to live in elevated areas, such as roots and attics.

Both of the above rat species are commonly adopted as pets, and make up part of the list of types of domestic rats. For more about what these rats eat, keep reading below!

Where do rats live?

A rat’s preferred environment will depend largely on the species. Rats are nocturnal animals, so you may not actually see them often. You can find rats in the garden, rats in the house, etc. A commonly asked question which many wonder is, ‘‘Where do rats hide?’’ Again, this will depend on whether or not it is an urban or rural rat. Generally, rats hide in rat nests. If you’re dealing with a rat in the garden, you can assume that it is hiding in a burrow. Because rats have flexible skeletons, they are able to move into tiny spaces, including, cracks in the wall and holes.

What do rats eat?

Be them city rats or wild rats, all rat species follow an omnivorous diet, which means that they consume both plants and animals. In rural environments rats generally eat fruits, leaves, plant stems, fungi, insects, grains, cereals, small mammals, fish, mollusks, eggs, snails and more. Do rats eat seeds? Yes, these are also among their varied diet!

In the wild, rats do not reject carrion and can even resort to cannibalism when desperate. This ability to adapt their eating habits is an incredibly important part of their survival among different environments, which is why they are also able to also live in cities. So, what do city rats eat? City or sewer rats eat all kinds of waste found in drains, rubbish dumps and sewers.

Water intake is also extremely important for all rodents. Generally, rats set up their nests near any any found water source. For this reason, rats also tend to drink poor quality water, which would be considered contaminated by human standard.

How to feed rats

Now that you know what rats eat, let’s analyze how to feed a rat. When feeding your rat, you should consider:

  • When offering your rat meats, this should be offered lightly cooked to avoid the presence of bacteria.
  • All fruits offered to your rat must be peeled, seeds and pips must be removed and it should be chopped well so that the rat can eat it without difficulty. In the case that you want to offer your rat more fiber, make sure to wash the fruit properly and only offer a small piece with skin.
  • Green leafy vegetables, such as spinach, can be offered washed and raw. Carrots should be peeled and chopped. Peas must also be peeled and, most importantly, completely thawed if originally frozen.
  • Corn can be offered raw but rice must be cooked.

As for the proportions of a rat’s diet, it should be based, predominantly, on seeds, fruits and vegetables. We suggest only offering your rat animal protein once or twice a week.

Because rats eat several times a day, we recommend leaving a seed mix in the cage for your rat to nibble on. If you leave your rat fruit and vegetables exposed for too long, it can become contaminated.

Most importantly, don’t forget the importance of changing your rat’s water regularly!

What do baby rats eat?

As mammals, baby rats first feed on their mother’s breast milk until approximately 21 days of age, at which point they begin to eat solid food. If you have found an orphaned baby rat and are wondering what to feed it, we suggest consulting a veterinarian who can offer you a special milk preparation appropriate for baby rats. You should never offer a baby rat cow's milk!

Difference between rats and mice

It’s very easy to confuse rats with mice, but although they are both part of the Muridae family, they are a different species. The most common differences between rats and mice include:

  • Rats can measure up to 30 centimeters in length, while mice only measure 15.
  • Rats have long legs and small ears, while mice stand out for their large ears and tiny legs.
  • A mouse’s whiskers are longer than a rats.
  • Mice usually have a light coat combined with dark tones, such as gray, white and brown. A rat’s coat, however, is mainly black or brown, although they may have white spots (but this is not as common).
  • Mice exhibit tamer behavior, while rats can carry a more aggressive temperament, which can manifested in squeals, ruffled hair and bites.

What do mice eat?

In the wild, mice follow a herbivorous diet and feed on fruits, leaves, stems, seeds, cereals, mushrooms, among others. Over time, mice in cities and urban environments have become accustomed to ingesting a broad spectrum of human waste and can be follow an omnivorous diet.

When it comes to feeding a domestic mouse, you can offer it a commercial mouse feed, small amounts of clean and fresh fruit and vegetable (remove skin and seeds) and some pulses. Make sure your mice have access to clean and fresh water.

Do rats eat cheese?

Rats can generally eat cheese, however, due to the fact that cheese is a very fatty food, we don’t recommend feeding your rat too much cheese. Offering your rat a little cube of cheese as a treat, now and then, is alright. But this consumption needs to be controlled.
