Truthfully, rats can eat just about anything! As opportunistic omnivores, many foods are safe for them to eat, but there are still some foods that are off-limits to them.
Pickles also fall in the “best avoided” category. You shouldn’t give them to your rat due to the high amounts of salt that they contain. However, they aren’t toxic. Your rat will be okay if they get a bite or two of a pickle. Read on to learn more about rats and pickles.
Why Pickles Are Not the Best for Rats
We don’t recommend adding much pickle to your rat’s diet. High salt levels can cause some issues; excessive sodium can strain a rat’s kidneys and cause dehydration or electrolyte imbalance. Many pickles also contain vinegar and spices that may irritate a rat’s gastrointestinal system.
Moreover, rats will rarely eat pickles. Their pungent smell turns off many rats. As a species, they tend to dislike strong-smelling foods. This behavior is partially evolutionary. Many strong-smelling foods are toxic to rats, like onions and garlic. Therefore, they evolved to avoid things that smelled particularly strongly.
The Potential Problems With Pickles
There are many types of pickles out there and quite a few ways to make pickles. Not all these types and methods are necessarily safe for your rat.
Often, pickles are made with primarily salt as the pickling agent. If you want to make pickles, you have to add salt—it’s in the definition of a pickle.
Salt
Some pickles have more than others. Therefore, it is essential to check the ingredient list and see exactly how much salt a particular pickle brand has.
Preferably, you want to feed your rat as little sodium as possible.
While they do need some sodium, they don’t need nearly as much as we humans do. After all, rats are incredibly tiny compared to us. Therefore, they don’t require as much salt to stay functional.
The amount of salt added to human foods (including pickles) is often far too much for most rats, although rats are a bit more tolerant of extra salt than other animals. Still, problems can develop over the long term if rats are fed high-sodium diets.
Similar to people, rats have been found to develop hypertension and renal injury if fed too much salt over their lifespan. Of course, this study used a large amount of salt — a small piece of pickle will not cause renal failure. Your rat would need to eat salt for days.
This study should make you think twice about regularly feeding pickles to your rat, though.
Sugar
Salt is the primary method of making pickles. However, sugar can also be added. You always have to add a decent amount of salt to make pickles, but some of this salt can be replaced with sugar.
This method creates a slightly sweeter and slightly less healthy pickle for your rat.
Excess sugar can cause many problems for our rodent friends. For instance, it can affect our rats’ molars and lead to tooth decay. A rat’s incisors are renewed throughout their lifespan, but not their molars. Once they’re affected by sugar, there is little that you can do about it. There aren’t many rodent dentists out there, after all.
Sugar can cause changes in gut flora. Many of the good bacteria in a rat’s stomach don’t eat sugar. But many of the harmful bacteria do. Therefore, a diet high in sugar can lead to excesses of certain gut flora.
Overconsumption of sugar has also been linked to aggression, mainly when consumed at a young age. This phenomenon likely occurs due to the dysregulation of the immune system, leading to increased inflammation throughout the rat’s body.
Some types of sugar are suitable for rats in small amounts, such as the sugars found in fruits. Berries are nutritious, for instance.
However, pickles do not fall into this category. The sugar found in pickles is added sugar, not the natural sugar found in fruit. It’s often refined and not healthy by any means.
What Type of Pickle Should I Choose?
We recommend choosing pickles that are moderately low in sodium and contain little sugar.
You don’t want to choose the pickle containing the most sodium, but you also don’t want to pick one that replaces some sodium with sugar.
Sugar is much worse for rats than sodium, especially at higher levels. Therefore, it is best to choose a moderately salty pickle rather than one utilizing sugar as the pickling agent.
When you head to the store to pick out pickles for yourself, knowing you may wish to share a tiny piece with your rat, this is what we recommend doing:
- Eliminate the pickles containing excess sugar. Carefully read the ingredient list to find the pickles that utilize sugar as a pickling agent. Immediately eliminate these from the possibilities.
- Check for extra ingredients. Look at the ingredient list. If the pickle is flavored or has extra ingredients, it may not be the best choice for your rat. You’re looking for plain pickles here, not jalapeño pickles, for example.
- Choose the pickle with the least sodium. Select the pickle with the least sodium. Again, this one should include little to no added sugar.
Can Rats Eat Flavored Pickles?
Once upon a time, there were only plain pickles. Then pickle companies realized that the people would pay good money for fancy pickles. This discovery led to the creation of flavored pickles. Now, even if you just like eating pickles straight out of a jar, you can find a whole host of options. Some of these taste good on a hamburger, too.
However, just because we enjoy flavored pickles doesn’t mean we should share them with our pet rodents.
The main problem with these pickles is that they include a wide variety of different ingredients. Different pickles have different flavorings added. Some of these are entirely safe, but others are not.
Either way, none of them are particularly healthy. Many flavored pickles have added sugar, which can be troublesome for rats.
Therefore, we recommend avoiding flavored pickles. Choose plain pickles only.
Flavored pickles probably won’t kill a rat, but they aren’t the best options either.
Can My Pet Rat Eat Dill Pickles?
Well, dill pickles present a different challenge for rats. They are primarily fermented in vinegar, not salt. However, they still have a small amount of salt added. Vinegar is acidic and may irritate your rat’s gastrointestinal system. Besides, dill pickles often contain garlic, which is toxic to rats, and spices, which may cause further gastrointestinal issues.
Sour pickles are much higher in salt, on the other hand. They don’t utilize vinegar as a fermenter, so they need more salt to compensate.
Sweet pickles are just what they sound like: sweet. They’re made with extra sugar, which is a poor option for your rat.
This is why, in general, we classify pickles as best avoided for rats. Each kind has a different downside, and there are not many benefits to make up for the risks.
Moreover, dill pickles often have a more pungent smell due to the vinegar. Many rats don’t like this and refuse to eat them.
There is no reason to force your rat to eat pickles, though. Therefore, we typically don’t recommend searching out pickles that are easier on their noses. Usually, the pickles that they’ll find the tastiest are also the ones that are unhealthy, such as sweet pickles.
Conclusion
Pickles are best avoided when it comes to something to share with your rat. There are different kinds of pickles, and each kind has potential problems for your rat. They can be high in sugar and salt, neither of which is suitable for rats. You’ll need to read the ingredient lists before choosing a pickle to give to your rat. Some may even contain garlic or onion, which are toxic to your rat.
Furthermore, many rats won’t eat pickles. They usually don’t like strong-smelling foods. Many of the foods that are toxic to rats also smell strong, like onions. Therefore, their dislike of strong-smelling foods helps keep them safe. While the pickles themselves are not toxic, many rats will avoid them just because they smell weird. So just enjoy your pickle, and offer your rat something else as a treat.
