Rats' Diet: What Do They Eat?

Rats are omnivores, meaning they eat a variety of foods, including vegetation, seeds, grains, and occasionally invertebrates and animal proteins. In the wild, they are opportunistic feeders, consuming anything from fallen fruit to carcasses. As pets, they require a balanced diet of commercial food pellets, fruits, vegetables, and other fresh foods. Proper nutrition is essential to prevent diseases and ensure they get the necessary nutrients and minerals.

Rats are omnivores

As pets, rats should be fed a diet that meets their nutritional requirements and provides enrichment. A good baseline diet for pet rats consists of a high-quality, fortified pellet or rodent block that ensures their protein, fat, fiber, vitamin, and mineral needs are met. Rats also need mental and physical enrichment, so it is important to provide them with a variety of appropriate food options to stimulate them and allow them to manipulate their food with their paws. Suitable foods include seeds, nuts, cooked eggs, grains, and small amounts of fresh fruit and vegetables.

It is important to note that rats should not be fed certain foods, such as onion, citrus fruits, walnuts, rhubarb, grapes, raisins, chocolate, avocado, garlic, coffee, tea, and alcohol, as these can be harmful or toxic. High-fat and sugary treats, such as nuts, seeds, and honey sticks, should also be limited, as rats can easily gain weight and are prone to health issues such as heart disease, liver disease, and tumour formation.

To encourage natural foraging behavior, rat food can be scattered around their cage and exercise area, and hidden in safe places for them to find. Rats also enjoy digging and chewing, so providing them with items like cardboard tubes, untreated softwood branches, and loose hay can help keep them mentally and physically enriched.

Proper nutrition is vital

Commercial food pellets designed specifically for rats can be a good option, as they contain the necessary balance of nutrients. These should be supplemented with fresh foods to provide additional micronutrients and keep mealtime interesting. Rats tend to prefer high-fat, high-calorie foods, so it is important to limit these in their diet to prevent obesity and health problems. Instead, offer a variety of low-calorie, low-fat options, such as apples, cherries, bananas, and other berries.

It is also important to provide multiple food options and hide food items in their cage to encourage natural foraging behaviour. Rats are social creatures, so it is recommended to keep at least two together, and it is important to provide enough food for all, as they will share with their companions.

In addition to a healthy diet, rats need mental and physical enrichment. This can come in the form of toys, such as natural chews or cardboard boxes, or loose hay, which provides an outlet for physical enrichment through play.

By providing proper nutrition and enrichment, you can help prevent diseases such as heart disease, liver disease, and tumour formation, and ensure your rat lives a long and healthy life.

Rats are social eaters

Rats are omnivores, so their diet can consist of a variety of foods. In the wild, they are both prey and predator, consuming a diverse omnivorous diet, including vegetation, seeds, grains, and occasionally invertebrates and animal proteins. They are also opportunistic feeders, feeding on carcasses and fallen fruit. This means that pet rats can be fed a variety of appropriate food options, including commercial food pellets, fruits, vegetables, seeds, grains, and nuts. Rats also enjoy the stimulation of being given whole or intact food, such as a cooled, unpeeled boiled egg, which they can work out how to break into.

It is important to note that rats have individual preferences for particular foods, and they can be neophobic, meaning they are sometimes hesitant to try new foods. Therefore, it is important to introduce new foods carefully and slowly over several days to avoid upsetting their stomachs. Rats also have a tendency to preferentially consume high-fat, high-calorie foods, so these should be limited and used as occasional treats rather than part of every meal.

Rats also enjoy natural foraging behaviour, so it is beneficial to scatter their food around their cage and exercise area instead of feeding them from a bowl. This encourages them to hold and manipulate their food in their paws, which they enjoy. Additionally, providing food hidden in safe places, such as in sand or gravel trays or inside cardboard tubes, can be enriching for rats.

Rats eat faeces

Rats are omnivores, meaning they eat a wide variety of foods, including vegetation, seeds, grains, and occasionally invertebrates and animal proteins. They are also known to eat faeces, a behaviour called coprophagy.

Coprophagy is a natural behaviour for rats, and they do it to absorb all the nutrients and minerals they need to stay healthy. Rats will regulate the amount of faeces they eat according to their nutritional needs. For example, they will eat more faeces when fed a nutritionally incomplete diet or when they are pregnant and have increased nutritional needs. Rats eat between 0-11% of their own faeces when fed a nutritionally complete diet.

Preventing rats from eating their faeces can lead to deficiencies of vitamin K, complex B vitamins, and biotin and can cause other vitamin deficiencies to develop. Rats need to eat fresh faeces, and if they are unable to, they can experience stunted growth. Rats excrete two types of faeces, similar to rabbits. One type, hydrous faeces, is not found in the cages of free-moving rats as it is usually eaten directly from the anal orifice. This type of faeces is believed to be covered with a mucus membrane that, once in the stomach, slows digestion and promotes fermentation, allowing a more effective breakdown of nutrients.

Rats should be fed a diet that meets their nutritional requirements and provides enrichment. A well-balanced, uniform, fortified pellet or rodent block free of artificial flavours, colours, and preservatives can form the largest part of a rat's diet. Rats also need mental and physical enrichment, which can be provided through play and toys such as natural chews, toilet paper rolls, cardboard boxes, and loose hay.

Rats enjoy foraging

Rats are omnivores, which means they eat a wide variety of foods. In the wild, they are both prey and predator, consuming a diverse diet of vegetation, seeds, grains, and occasionally invertebrates and animal proteins. They are also opportunistic feeders, consuming anything from fallen fruit to carcasses.

Rats are highly intelligent and social animals, and they enjoy the thrill of the hunt. They would naturally spend a lot of time foraging and searching for food. As pets, they can be encouraged to engage in natural foraging behaviour. This can be done by scattering their food around their cage and exercise area, rather than feeding them from a bowl. Rats enjoy holding and manipulating food in their paws, so they will appreciate having to work a little for their meals. Food can be hidden in safe places, such as in cardboard tubes or under gravel, to simulate a natural foraging experience.

Rats also enjoy variety in their diet. They can be particular about their food, developing individual preferences. A mix of food items can be offered, and these can be changed regularly to keep mealtimes interesting. Rats can eat commercial food pellets, which are formulated to meet their nutritional requirements. However, these should be supplemented with fresh foods such as fruit, vegetables, cooked egg, grains, and seeds. Rats also enjoy whole or intact foods, such as unpeeled boiled eggs, which provide them with the challenge of breaking into their meal.

Rats are naturally attracted to sweet and fatty foods, but these should be limited to occasional treats as they can cause health problems if consumed in excess.
