Can Rats Eat Cheese? (Read This First!)

Can Rats Eat Cheese

Cheese is a dairy product made from the curdled milk of cows, goats, sheep, or other mammals. The basic process involves coagulating the milk, separating the whey, and then allowing the curd to ripen and mature. The variety of cheeses available is vast, ranging from soft and mild to hard and sharp, with different flavors, textures, and nutritional profiles.

And they are extremely delicious and cheesy!

But can rats eat cheese too?

Yes, rats can indeed eat certain types of cheese in moderation. Many rats enjoy cheese, and it can be a source of protein, fat, and calcium in their diet. However, it’s crucial to offer cheese as an occasional treat rather than a primary food source. High-fat and high-calorie foods like cheese can contribute to health issues such as obesity if overfed.

So, should you feed cheese to your rats or not?

Let’s find out!

Can Rats Eat Cheese?

Yes, rats can eat cheese in moderation.

Many rats enjoy cheese, and it can be a good source of protein and fat for them. However, it’s important to provide cheese as an occasional treat and not as a staple in their diet.

But cheese is high in fat, and while rats need some fat in their diet, too much can lead to health issues such as obesity.

Limit the amount of cheese you give to your rat and offer it as an occasional treat.

Rats require a balanced diet that includes a mix of fresh fruits, vegetables, grains, and proteins. Cheese can be part of this variety, but it shouldn’t replace other essential components of their diet.

Some cheeses are better than others for rats. Stick to milder cheeses, as highly processed or very strong cheeses may be too rich for them.

Cottage cheese, mild cheddar, or mozzarellas are good choices.

So, yes rats can eat cheese but in moderation!

Are Rats Lactose Intolerant?

Rats are generally not lactose intolerant. Unlike some mammals, such as certain adult humans, many adult rats can digest lactose without any issues.

Are Rats Lactose Intolerant

Lactose is the sugar found in milk and dairy products.

Rats are born with the ability to digest their mother’s milk, which contains lactose. As they grow, they continue to produce the enzyme lactase, which is needed to break down lactose. This enzyme helps them digest lactose throughout their lives.

While most rats can tolerate lactose, it’s essential to offer dairy products in moderation. Excessive consumption of high-fat and high-calorie dairy products, like cheese, can lead to health problems such as obesity.

Additionally, individual rats may have varying tolerances to different foods, so it’s always a good idea to introduce new items into their diet gradually and observe their reactions.

Is Cheese Healthy for Rats?

Cheese can be a healthy addition to a rat’s diet when offered in moderation. While it should not replace a balanced and varied diet, cheese can provide some nutritional benefits for rats.

A typical serving of cheese may (28 grams) contains:

  • Calories: Approximately 110 calories
  • Protein: About 7 grams
  • Fat: Around 9 grams
  • Calcium: Roughly 200 milligrams

Other benefits of cheese may include:

Protein Source

Cheese is a good source of protein, which is essential for the growth, maintenance, and repair of tissues in a rat’s body.

Protein is crucial for overall health and helps support muscle development.

Calcium Content

Cheese contains calcium, which is important for maintaining strong and healthy bones.

Rats, like all animals, require a sufficient amount of calcium for skeletal integrity.

Caloric Density

For rats that may have higher energy needs, cheese can serve as a calorie-dense snack.

This can be beneficial for growing rats, pregnant or nursing females, or rats with increased energy requirements.


Many rats find cheese to be palatable, and using it as a treat can encourage them to consume other essential nutrients when combined with a well-balanced diet.

Risks of Overfeeding Cheese to Rats

Risks of Overfeeding Cheese to Rats

While cheese can be a tasty and nutritious treat for rats when given in moderation, overfeeding can lead to various health risks.

Here are some of the risks of involved:


Cheese is high in fat and calories. Overfeeding can lead to obesity in rats, which poses various health risks.

Obese rats may experience difficulty moving, grooming, and engaging in normal physical activities.

Digestive Issues

Too much fat in the diet, especially from rich foods like cheese, can lead to digestive issues such as diarrhea and stomach upset.

Rats may also experience discomfort and a decreased appetite.

Dental Problems

Rats have continually growing incisors, and a diet high in sticky or sugary foods, such as some types of cheese, can contribute to dental problems.

Over time, dental issues can affect the rat’s ability to eat and lead to pain.

Heart and Cardiovascular Issues

High-fat diets can contribute to heart and cardiovascular problems.

While small amounts of fat are necessary for a rat’s diet, excess fat intake from overfeeding on cheese can be detrimental to their cardiovascular health.

Thus, it’s important to offer cheese as an occasional treat, not a staple in the rat’s diet.

Additionally, provide a well-balanced and varied diet that includes fresh fruits, vegetables, grains, and a nutritionally complete rat pellet or block.

How Much Cheese Can Rats Eat?

The amount of cheese that rats can eat depends on various factors, including the size, age, and overall health of the rat.

For example, a small piece is generally sufficient as a treat for a rat.

Rats are small animals, so even a small amount of cheese can be a significant portion of their daily caloric intake.

Cheese should be considered a treat rather than a mainstay in a rat’s diet, as it is high in fat and can lead to health issues if consumed excessively.

Also,pay attention to how your individual rat responds to cheese. Some rats may be more sensitive to dietary changes than others.

If you notice any digestive issues or changes in behavior after introducing cheese, consider adjusting the amount or frequency.

Can Rats Eat All type of Cheese?

Can Rats Eat All type of Cheese

While rats can eat many types of cheese, it’s important to be selective and cautious about the types offered.

Not all cheeses are suitable for rats, and some may pose risks due to their composition.

Here are some types of cheese rats can eat:

Mild Cheeses

Mild cheeses like cheddar, mozzarella, Swiss, and mild varieties of other cheeses are generally safe for rats.

These cheeses are not overly processed or strongly flavored, making them more suitable for rats.

Avoid Strongly Flavored or Processed Cheeses

For example, Blue cheese, feta, and heavily processed cheeses.

Strongly flavored cheeses may be too intense for rats, and highly processed options can contain additives that may not be suitable for them.

High Salted Cheese

Some aged or hard cheeses with high sodium content are not ideal for rats.

Excessive salt intake can be harmful to rats, leading to health issues.

Choose low-sodium or moderate-sodium options.

Avoid Moldy Cheese

Avoid cheese with visible mold growth.

Mold can be toxic to rats, so it’s essential to avoid any cheese with mold. Stick to fresh and mold-free options.

Always introduce new types of cheese gradually and in small amounts. Observe your rats for any adverse reactions, such as digestive issues or changes in behavior.

Can Rats Eat Cheddar Cheese in Small Amounts?

Yes, rats can eat cheddar cheese in small amounts as an occasional treat. Cheddar cheese is a good source of protein and fat, and many rats find it palatable.

However, it’s important to keep the serving size small and offer it in moderation.

For example, a small amount or a tiny cube is generally sufficient as a treat for a rat.

Avoid overfeeding; rats should receive it as an occasional treat, perhaps a couple of times a week at most.

While cheddar cheese contains beneficial nutrients such as protein and calcium, it’s not a complete and balanced diet on its own.

Remember that the key is moderation.

What Other Dairy Products Can Rats Have?

Rats can eat a variety of dairy products, but it’s important to offer them in moderation as treats rather than as the primary component of their diet.

Here are some dairy products that rats can have in small amounts:

  • Yogurt: Plain, Unsweetened Yogurt: This is a good source of probiotics, calcium, and protein. Choose plain varieties without added sugars or artificial sweeteners. Probiotics can contribute to a healthy digestive system.
  • Cottage Cheese: Low-Fat Cottage Cheese: It is a good source of protein and calcium. Opt for varieties with lower fat content to avoid excessive fat intake.
  • Milk: Lactose-Free Milk: While rats can digest lactose, offering lactose-free milk may be easier on their digestive system. Milk can provide additional calcium and protein.
  • Cheese: Mild Cheeses: In addition to cheddar, rats can also have small amounts of mild cheeses like mozzarella or Swiss. Avoid highly processed or strongly flavored cheeses.
  • Buttermilk: Low-Fat Buttermilk: It contains less fat than regular milk and can be a source of protein and calcium. However, offer it in moderation.

Note – choose products without added sugars, sweeteners, or artificial additives, as these can be harmful to rats.

It’s essential to remember that while these dairy products can be included in a rat’s diet, they should not replace the core components of their nutrition.

Final Thoughts

To sum up, rats can indeed eat cheese in moderation, and it can serve as a tasty and nutritious treat for them. Cheese provides a good source of protein, fat, and calcium, contributing to their overall diet.

However, it’s crucial to emphasize moderation, as overfeeding can lead to potential health risks such as obesity, digestive issues, and nutrient imbalances.

When offering cheese to rats, choose mild varieties like cheddar, mozzarella, or Swiss, and provide it in small portions, perhaps a small amount, a couple of times a week.

Remember, every individual is different, so respect their choices!
