Rats make wonderful pets, but it’s important to feed them the right diet to keep them healthy. Many rat owners wonder if it’s okay to feed their pet rats cat food. After all, rats are known to eat almost anything. However, cat food is not a good choice for rats, even though they may like the taste. Let’s explore why.
Can Rats Eat Cat Food?
The short answer is no, rats should not eat cat food on a regular basis. While rats can eat small amounts of cat food occasionally without major problems, a diet of cat food does not provide the right nutrition for rats.
There are a few key reasons why cat food is not suitable for rats:
- Cats are carnivores, while rats are omnivores
- Cat food is high in protein and fat
- Cat food lacks essential nutrients rats need

Cats are Carnivores, Rats are Omnivores
One of the biggest differences between the dietary needs of cats and rats is that cats are obligate carnivores. This means they require animal protein to survive. Their bodies are designed to get most of their nutrients from meat.
In contrast, rats are omnivores. While they do need some animal protein in their diet, they also require plant-based foods like grains, vegetables, and fruits. Rats cannot thrive on the high protein, meat-based diet that cats need.
Cat Food is High in Protein and Fat
Because cats are carnivores, commercial cat foods are formulated to be very high in animal protein and fat. This is too much for rats.
Rats do need some protein and fat in their diet, but in much lower amounts than cats. Feeding rats a diet that’s too high in protein and fat can lead to obesity and other health issues over time.
Cat Food Lacks Essential Nutrients for Rats
Not only does cat food contain too much of certain nutrients like protein and fat, it also lacks other essential vitamins, minerals, and fiber that rats need to stay healthy.
Rats require a balanced diet with the right mix of nutrients. Commercial rat food and rat blocks are specifically formulated to contain everything pet rats need. Cat food just doesn’t measure up.
What Happens if a Rat Eats Cat Food?
If a rat sneaks a bite or two of cat food, it’s usually not a big deal. Eating cat food occasionally or in small amounts is unlikely to harm a healthy rat.
However, if a rat eats too much cat food, especially over a long period of time, it can lead to health problems such as:
- Nutritional Imbalance: Cat food does not provide the balanced nutrition that rats need.
- Obesity: High protein and fat content can lead to weight gain and related health issues.
- Vitamin Deficiency: Lack of essential vitamins and minerals can cause deficiencies.
- Digestive Issues: High protein and fat can be hard for rats to digest, leading to gastrointestinal problems.
Rats have sensitive digestive systems that are designed for an omnivorous diet. The high protein and fat content in cat food can be difficult for their bodies to process in large quantities.

The best option for feeding pet rats is commercial rat food, specifically formulated to meet their nutritional needs. These foods provide a balanced diet with the right amounts of protein, fat, vitamins, and minerals.
Fresh Foods
Rats benefit from a variety of fresh foods. Here are some safe options:
- Fruits: Apples (without seeds), bananas, berries, melons
- Vegetables: Carrots, broccoli, peas, sweet potatoes (cooked)
- Proteins: Lean meats, eggs, beans (cooked)
Rat blocks or pellets should make up the biggest part of a pet rat’s diet. These are nutritionally complete and balanced to meet rats’ needs. Supplement the blocks with small amounts of fresh foods for variety.
Treats are fine to give rats sometimes, but should only make up a small part of their overall diet. Avoid high-fat, sugary treats.

Storing Rat Food Safely
In addition to choosing the right food for pet rats, it’s also important to store their food properly to keep it fresh and safe. Follow these tips:
- Keep dry food in an airtight container
- Store food in a cool, dry place away from sunlight
- Refrigerate fresh foods and use within a few days
- Throw away any moldy or spoiled food
- Clean food bowls and containers regularly
Proper food storage helps prevent rats from getting sick from spoiled or contaminated food. It also keeps their food tasting and smelling appealing so they’ll want to eat it!
The Bottom Line
While rats may like the taste of cat food, it’s not a suitable diet for them. Rats are omnivores with specific nutritional needs that are different from cats.
To keep pet rats healthy, feed them a balanced diet that includes:
| Rat Food | Amount |
|---|---|
| Commercial rat blocks/pellets | Unlimited, as main diet |
| Fresh veggies and fruits | Small amounts daily |
| Lean protein like egg or meat | Occasional small amounts |
| Healthy treats like seeds or nuts | Limited, occasional treats |
Avoid feeding rats cat food or dog food on a regular basis. If you’re unsure about what to feed your pet rats, ask a veterinarian who is knowledgeable about rats for advice.
With a nutritious, rat-appropriate diet, your pet rats will thrive! Provide them with the right balance of nutrients in foods they enjoy to keep them happy and healthy for years to come.
