Raising a pet rat can be a rewarding experience, and it’s not all that difficult to accomplish. These rodents are opportunistic omnivores that will eat just about anything that they can find. However, not all foods are equal when it comes to the nutrition that they provide your pet. You might wonder about the safety of the different vegetables that you grow in your garden, including whether cucumbers are safe to feed to rats.
The short answer is yes. You can feed cucumbers to your pet rat in moderation, but there are a few things to consider before making these fruits a regular part of their diet. Keep reading as we look over the benefits and potential dangers of feeding cucumbers to your pet.
The 2 Reasons Cucumbers Are Bad for Pet Rats
1. Water Content
While rats do require plenty of fresh water in their diet, the high water content in a cucumber can lead to diarrhea if your pet rat eats too much of it. A cucumber is 96% water, so it won’t take much.
2. Pesticides
Unless you purchase pesticide-free cucumbers from the grocery store or grow them in your garden, there is a good chance that there will be pesticides on the skin of a cucumber, so it’s important to wash it well before serving it to your pet. Soaking it for at least 20 minutes in cool water with a few tablespoons of baking soda can help remove any dangerous chemicals before you serve the fruit to your rat.

The 2 Reasons Cucumbers Are Good for Pet Rats
1. Low in Calories and Fat
The cucumber has 45 calories in an 11-ounce serving, so you won’t need to worry about your rat gaining weight or developing diabetes from eating this food. The primary reason for the low number of calories is that it’s 95% water. It also contains no fat that could potentially cause health problems for your pet.
2. Vitamins and Minerals
Cucumbers do not contain a lot of nutrients, but it does have vitamins A, K, and a small amount of vitamin C. It also provides potassium, phosphorus, and manganese, along with antioxidants that can help boost your pet’s immune system and help it fight off disease.

How Do I Feed My Rat Cucumber?
Around 10% to 20% of your pet rat’s diet should consist of healthy vegetables. However, since there are not many nutrients in cucumbers, most vets recommend adding a small amount of other, more nutrient-rich vegetables to help give your pet the nutrition that they need. We recommend removing the skin of a cucumber, even though it’s safe to eat, to reduce the risk of pesticide poisoning and adding 3 or 4 half-inch cucumber cubes to other vegetables every 4 or 5 days. You can also hand-feed small pieces as treats during your bonding time if your pet enjoys eating cucumbers.
Alternatives to Cucumber
You can substitute several foods for cucumbers or create a salad to accompany them. Examples include peas, potatoes, cranberries, blueberries, apples, rice, and dates. Any of these foods will provide your pet with nutritious additions to their meals. We recommend creating a salad with at least two of these vegetables, plus a bit of cucumber, for a healthy and varied diet.

Can Rats Eat Pickles?
Since you make pickles from cucumbers, it makes sense to wonder if your pet rat can eat this food too. The short answer is yes; like cucumbers, your pet rat can eat pickles in small amounts. However, unlike cucumbers, pickles contain a lot of salt, which can cause your pet to retain water and cause other health problems down the road. Most animals tend to dislike the brine that pickles are kept in, so there is little chance that you will get your pet rat to eat enough pickles to worry about the salt content. However, if your pet does enjoy pickles, you should provide only tiny portions as occasional treats.

What Should My Rat Eat?
The bulk of your pet rat’s diet should be commercial rat food. Scientists formulate commercial animal food to provide pets with complete and balanced meals that keep them healthy and allow them to live full lives. These foods are fairly inexpensive and will last a long time.

Summary
A pet rat can eat a cucumber without worry, but it won’t provide your pet with much nutritional value, and it could lead to diarrhea due to the high water content. If you are growing it in the garden or your rat has expressed a desire for it, you can feed your pet small pieces of cucumber every few days mixed with other veggies to help provide them with a varied diet. However, with so many healthier options like peas, potatoes, and apples available, limiting cucumbers to occasional treats might be better.
