Rats as a pet

Before knowing what rats eat, it is very important to know how to differentiate these small mammals from other domestic rodents such as hamsters. This is because although they have a similar appearance and diet, they are completely different species. Here are some general characteristics of rats:

  • Rats are generally slender with a pointed head, large eyes, and prominent, thinly furred ears.
  • They have moderately long legs and long, sharp claws.
  • The bald soles of their narrow hind feet possess fleshy pads of variable size, depending on species.
  • Domestic rats live an average of 2-3 years.

Rat digestive system

Now, focusing on the digestive system of mice, which is what will allow us to know what they eat, we can say that they are mainly herbivores, so their digestive system is adapted to consume plant matter. However, today they can be considered omnivorous animals since in the wild they will occasionally feed on insects.

After food is eaten, it is broken down and digested by the rat's stomach and digestive system. Vegetable matter is degraded in the cecum, but it does not absorb the resulting proteins and vitamins. Lastly, the waste is expelled through the anus.

Rat teeth

On the other hand, it is important to note that their incisor teeth grow continuously, so they must be filed through food intake or through chewing. If your rat cannot wear down these teeth, they can develop pain and mouth problems that will prevent the animal from eating and, therefore, can die from extreme physical weakness.

To avoid this, we will need to provide our pet rat with safe elements for them to chew and gnaw, such as:

  • Cardboard
  • Coconut shells
  • Hay cubes
  • Unbleached loofah
  • Pumice stone
  • Seagrass

What domestic pet rats eat

What do pet rats eat? Pet rats eat a mainly plant-based diet with a variety of fruits and vegetables. Many rat caregivers will also provide their pet rat with mouse/ rat pellets.

How much does a rat eat in a day?

Rats will eat between 12 to 20g of dry mix a day. However, if you feed them lots of protein and carbohydrates, you will need to reduce this amount. Vegetables can be fed freely as they have low calories and provide great nutritional value for your pet rat.

Since rats are very small animals, it's best to feed them small amounts of food several times a day. For better guidelines, be sure to ask the adoption centre or breeder you get your rat from. This is because there are many different types of domestic rats, some smaller than others. Also, if your rat is pregnant, nursing, or still growing, their food intake needs will likely increase.

In regards to their nutrition, rats generally need their diet to be about 75- 80% carbohydrates, 12 - 20 % protein and around 4 - 6% of fat. Keep in mind that too much protein can cause your rat to itch, causing scabs.
