Rats are omnivorous scavengers that have evolved to survive in diverse habitats with varied diets. Their diet may differ based on their location, but certain behaviours remain consistent. Rats need to nibble on unfamiliar foods to gauge their safety, and they exhibit distinct preferences based on their environment. In natural settings, a rat's diet consists of grains, seeds, nuts, fruits, plants, and occasionally smaller animals or insects. Urban rats, on the other hand, scavenge garbage, meat, pet food, and human leftovers. Rats require stimulation and enjoy the company of their owners. They need a fresh, healthy, and balanced diet with food provided in ceramic bowls to avoid ultrasound noise. Pellet diets are commonly recommended, but they should be rat-specific and include at least 16% protein and 4-5% fat content. Rats also benefit from eating vegetables, fruits, and other fresh foods in small amounts to avoid diarrhoea.

What You'll Learn
Rats need a nutritionally balanced diet
Rats are omnivores, which means they eat a variety of foods, including fruits, vegetables, grains, seeds, and meats. A rat's diet should be nutritionally balanced and complete to maintain optimum health. The basis of a rat's diet should be commercially available pellets or lab blocks made specifically for rats. These should be given to them in open ceramic bowls, which allow them to carry and handle their food.
Pellets or lab blocks should make up the majority of a rat's diet, but they can also be offered a variety of fruits, vegetables, small amounts of cooked egg or lean meat, and occasional whole grains such as bread, cereal, and cooked pasta and rice. It is important to ensure that the rat pellets have at least 15%-16% protein content and 4%-5% fat content for a balanced rat diet.
Rats are prone to obesity, so it is important to control their caloric intake and couple it with stimulating activity. Rats commonly overeat when they are bored, so it is important to provide them with a variety of food options to keep mealtime interesting. It is also recommended to give them puzzles to solve for their food, put them in multi-level cages, or let them run around in a safe environment to keep their weight under control.
In addition to the right balance of fiber, protein, and fat, rats need the appropriate balance of vitamins and minerals. Vitamin D is crucial as it allows rats to process dietary calcium. B vitamins help with neurological functions, and vitamin C helps keep their immune system strong. Rats also need to eat fresh faeces to absorb all the nutrients and minerals they need to stay healthy.

Pellets or blocks are a good staple
Rats are omnivores with a very high metabolism, which means they need to eat frequently and require a balanced diet. Pellets are a good staple food for rats because they are formulated to provide all the nutrients that rats need. They are also convenient for owners, as they can be left in a rat's cage and will keep for a long time.
The best rat pellets are those that provide a balanced diet. Pellets should have at least 16% protein content and 4-5% fat content. It is also important to vary the size of the pellets to avoid difficulties in eating habits, especially for young rats. Bigger-sized pellets can motivate rats' natural eating behaviours, which are observed in the wild. Rats in the wild tend to gnaw on larger food sources, and bigger pellets require more chewing, aiding in the maintenance of their teeth.
There are many good commercial pellet options available, such as Oxbow Essentials Adult Rat Food, which cuts out unhealthy ingredients while satisfying a rat's omnivorous palate. Mazuri's Vegetarian Rat and Mouse Diet is another good option, as it uses much larger pellets or "blocks", which are better for rats' teeth. However, these blocks tend to get dustier and shed more crumbs.
It is important to note that rats also need food enrichment and variety in their diet. Pellets should be supplemented with small amounts of fruit, vegetables, cooked egg, grains, and seeds. These should be given as part of their daily food allowance, not in addition to it, or it could cause obesity or health problems. Rats also enjoy holding and manipulating food in their paws, so it is a good idea to encourage their natural foraging behaviour.

Obesity is common in rats
Rats are omnivores, meaning they eat a combination of fruits, vegetables, and meats. A healthy rat diet consists of mostly fresh fruits and vegetables, plus a small portion of rat pellets or rat cube food daily. It is important to offer your rat a diverse diet to meet nutritional requirements and provide enrichment.
To prevent obesity in rats, owners should feed them a limited quantity of nutritionally balanced rat pellets supplemented with small amounts of vegetables and fruit. Rats should work for some of their food, and food can be offered as a reward at the end of a maze or at the top of a multilevel cage. This encourages exercise and provides mental stimulation.
Rats should be fed twice a day – in the morning and evening – as they feed mainly at dawn and dusk. Their diet should include insoluble fibre, which passes through the digestive tract relatively unchanged, promoting gut motility and supporting overall gut health. It is also important to provide a continuous supply of fresh, clean drinking water, in bottles rather than bowls to avoid contamination.

Rats need variety in their diet
Rats are omnivores, which means they eat a variety of foods, including fruits, vegetables, grains, seeds, and meats. A rat's diet should be varied and include a mix of fresh, whole foods and commercial rat food.
Commercial rat food, such as pellets or lab blocks, is designed to provide rats with the nutrients they need. These foods are typically fortified with vitamins and minerals and can be left out for rats to eat at their leisure. However, it's important to read the ingredient list and guaranteed analysis to ensure the food is of good quality and meets the rat's nutritional needs.
In addition to commercial rat food, rats should also be offered a variety of fresh, whole foods. This can include vegetables such as broccoli, carrots, and kale; fruits such as apples, bananas, and berries; and small amounts of cooked egg, lean meat, and whole grains. Rats also enjoy manipulating food with their paws, so offering them foods that encourage natural foraging behaviour, such as seeds or nuts in the shell, can provide mental and physical enrichment.
It's important to offer rats a variety of foods to ensure they get the nutrients they need and to keep mealtime interesting. Rats can be picky eaters, so a slow introduction to new foods is key. Additionally, rats are prone to obesity, so it's important to control their caloric intake and provide stimulating activities to keep them active and healthy.
Overall, by offering a variety of commercial rat food and fresh, whole foods, rat owners can ensure their pets are getting the nutrition they need while also providing enrichment and mental stimulation.

Rats need constant access to fresh water
Rats are prone to obesity, so it's important to monitor their food intake and provide a balanced diet. The basis of a rat's diet should be commercially available pellets or lab blocks made specifically for rats. These can be left available to your rat at all times and will provide the protein, fat, fibre, vitamins, and minerals they need.
In addition to rat pellets or blocks, it's important to offer your rat a variety of fresh foods to ensure they get enough nutrients. Rats are omnivores, so their diet should include a combination of fruits, vegetables, and meats. However, be mindful of the serving sizes as rats only need small amounts of food.
Some good options for fresh foods include:
- Vegetables: broccoli, carrots, kale, parsley, squash, etc.
- Fruits: apples, bananas, berries, melons, etc.
- Lean meat: boiled chicken, cooked lean red meat (steak, pork, lamb), etc.
- Eggs: boiled or cooked.
- Whole grains: bread, cereal, cooked pasta, and rice.
It's important to avoid feeding rats certain foods that may be harmful, such as onion, citrus fruits, grapes, chocolate, and high-fat or high-sugar foods.
