Raising a pet rat can be a rewarding experience, and it’s not very difficult to accomplish. They are opportunistic omnivores that will eat just about anything they can find, but not all foods are equal when it comes to the nutrition they provide your pet. We often get asked about the safety of different vegetables you might grow in the garden, and the one we see most frequently is whether cucumbers are safe to feed rats.

The short answer is yes. You can feed your pet rat cucumber in moderation, but there are some things to consider before making it a regular part of its diet. Keep reading while we look over the benefits as well as potential dangers of feeding cucumbers to your pet rats.


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 cucumber can lead to diarrhea if your pet rat eats too much of it. Cucumber is 96% water, so it won’t take much.

2. Pesticides

Unless you purchase organic 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 the cucumber, so it’s important to wash them well before serving them to your pet. Soaking them for at least 20 minutes in cool water with a few tablespoons of baking soda can help remove the dangerous chemicals before you serve the cucumber 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, as we mentioned earlier. 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 provide vitamins A, K, and a small amount of vitamin C. It also provides potassium, phosphorus, and manganese, as well as antioxidants that can help boost your pet’s immune system and help it fight off disease.

How Do I Feed My Rat Cucumber?

Ten to twenty percent of your pet rat’s diet should consist of healthy vegetables. However, since there are not many nutrients in cucumbers, most experts recommend adding a small amount to a salad of other more nutrient-rich vegetables to help give your pet the nutrition it needs. We recommend removing the skin, even though it’s safe to eat, to reduce the risk of pesticide poisoning and adding three or four half-inch cubes to other vegetables every four or five days. You can also hand-feed small pieces as a treat during your bonding time if your pet enjoys eating cucumbers.

Alternatives to Cucumber

You can use several foods as an alternative to 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 a nutritious addition to its diet. 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 as well. 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 avoid the brine that pickles are kept in, so there is little chance you will get your pet rat to eat enough pickles to worry about the salt content. However, if your pet does enjoy pickles, you will need to provide only tiny portions as an occasional treat.

What Should My Rat Eat?

The bulk of your pet rat’s diet should be commercial rat food. Scientists formulate commercial food to provide your pet with a complete and balanced meal that keeps it healthy and allows it to live a full life. These foods are fairly inexpensive and will last a long time.

Rats can eat 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 some other veggies to help provide a varied diet. However, with so many healthier options like peas, potatoes, and apples available, limiting cucumbers to an occasional treat might be better.
