Salt is a mineral that most mammals need. But, what about your fur babies? Do guinea pigs need salt licks?

Typically, guinea pigs don’t need salt licks. As long they’re fed a high-quality, well-balanced diet, they’re getting enough minerals and salt from what they eat. Which means, they donā€™t need salt licks. In extreme cases, if a guinea pig’s diet isn’t good enough to offer them the minerals they need, a vet might recommend a salt lick.

By the end of this article, you’ll know everything there is to know about whether guinea pigs need salt licks or not. But, first let’s begin with…

What’s A Salt Lick, Anyway?

A salt lick is a mineral deposit that animals eat to improve their nutrition. Salt licks usually come in the form of a block, and they are made out of either salt deposits or purified sources.

Salt licks have a lot of benefits for animals. One example is that it helps keep their hydration levels healthy.

It is also important for restoring electrolytes after they have been lost during exercise or a lot of movement. Electrolytes are minerals that help with muscle function and fluid balance in the body.

Salt licks can also help with digestion and nutrient absorption in some cases.

In other words, salt licks are generally good for some animals. But, slow down before you offer one to your guinea pig. Let’s dive into…

Why Don’t Guinea Pigs Need Salt Licks?

a tip about guinea pigs needing salt licks

Guinea pigs don’t usually need salt licks because they can get the sodium they need from their food. If they eat too much salt, it can cause health problems like dehydration and high blood pressure.

Sodium is an essential mineral for guinea pigs. It helps with fluid balance, muscle contractions, and maintaining a healthy nervous system.

But, you know that too much of anything is usually not good. The same goes for sodium. When guinea pigs eat too much sodium, their bodies have a hard time getting rid of it.

Itā€™s getting a bit technical, right? Let me break it down a little more.

You see, guinea pigs use their kidneys to remove surplus sodium from their systems. When they eat salt licks, they may end up with more sodium than they actually need.

The high amount of sodium forces the kidneys to overwork. That’s when kidney damage or failure can occur.

So, to avoid trouble, don’t offer salt licks to your guinea pig – well, unless recommended by the vet. As long as your pet is enjoying a healthy diet, the amount of sodium from the food is enough. So, they donā€™t need a salt supplement.

What’s a Mineral Wheel? 

A mineral wheel is a block of salt and other minerals that guinea pigs can nibble on for minerals. It’s much like a salt lick, but it has other minerals that guinea pigs need like calcium and phosphorus.

As the name suggests, a mineral wheel takes the shape of a wheel. It usually comes with a hole in the center. That makes it easy for guinea pigs to grab and nibble on it.

Do Guinea Pigs Need Mineral Wheels? 

Typically, guinea pigs don’t need mineral wheels either. They can get all the minerals they need from their food. The only time a mineral wheel might be necessary is if your guinea pig isn’t getting a well-balanced diet. If that’s the case, your vet might recommend one.

You might have seen your friend’s pigs nibbling on mineral wheels. But that doesn’t make it necessary for your guineas. Remember that all guinea pigs have unique needs. So, don’t offer mineral wheel to your pet unless they actually need it.

Mineral wheels are only necessary for guinea pigs with mineral deficiencies. A few signs should give you a clue that your pet has mineral inadequacy. They include:

  • weight loss
  • sluggishness
  • lack of appetite.

However, these symptoms might not always mean that you have a mineral deficiency problem.

To be sure, you should bring your guinea pig to a vet. The expert will do some tests to find out the exact problem. Then, they will prescribe what they think is best for your guinea pig.

How Much Salt Do Guinea Pigs Need? 

Guinea pigs only need a small amount of salt in their diet. In fact, the quantity they need is too little that they can get enough supply from their natural food. A lot of salt may cause your little friends more harm than good. 

Having low levels of sodium can lead to a number health problems. However, this doesn’t mean that the more salt your pig gets, the healthier it will be.

To put things into perspective, a human only needs about 2000mg of sodium daily. Cavies only need a teeny – tiny fraction of that.

Can Salt Hurt Guinea Pigs?

Do Guinea Pigs Like Salt? 

a funny meme about guinea pigs needing salt licks

Guinea pigs generally like the taste of salt. But, that doesn’t mean they need it or that you should offer it to them as a treat.

A lot of guinea pigs will try to nibble on anything they can get their teeth on – even salt licks. They’re just natural gnawers. So, if you offer them a salt lick, there’s a good chance they’ll try to chew on it.

Did you know? Guinea pigs have teeth that never stop growing. That’s why they need to gnaw on hay constantly or something hard occasionally to keep their teeth in check.

Why Does Your Guinea Pig Lick You? 

Your guinea pig licking you is usually a sign of affection or cry for attention. It can also mean that your little friend likes the way you taste. Sometimes it can be that they like the saltiness of your skin.

In some cases, your guinea pig might be trying to tell you that they’re hungry. So, if you notice your guinea pig licking you more often than usual, it might be time to feed them.

Other than that, guinea pigs usually lick their owners to show affection or as a way of begging for food.

In most cases, the message is of how much they feel close and bonded to you. But if you haven’t spent a lot of time with your cavy, licking could mean that they want more of your time.

Do Baby Guinea Pigs Need A Salt Lick Or Mineral Wheel?

Baby guinea pigs usually don’t need a salt lick or mineral wheel. Salt licks and mineral wheels are appropriate when your pet’s mineral levels need a boost. Otherwise, don’t offer it to your youngster pig.

Like adult pigs, baby guinea pigs should get everything they need from their diet. So, unless confirmed by the vet, don’t introduce mineral wheels and salt licks to them.

Do Pregnant Guinea Pigs Need A Salt Lick Or Mineral Wheel?

a tip about guinea pigs needing salt licks

Pregnant guinea pigs don’t need a salt lick, and they don’t need a mineral wheel. Like normal pigs, pregnant guinea pigs can have all the minerals they need from their food. So, unless the suggestion is from the vet, don’t offer your pet salt lick or mineral wheel.

Pregnant guinea pigs need more minerals and vitamins than average pigs. However, that does not mean that they need mineral supplements. You don’t want your pig to have too much of one mineral in their system because it could lead to health problems, some of which can be fatal.

So, unless your guinea pig has a mineral deficiency or your vet tells you to, don’t give them any supplements. Only focus on providing them with a balanced and healthy diet, and they’ll be fine.

How Do Guinea Pigs Get Bladder and Kidney Stones?

Bladder and kidney stones are hard deposits that form in your pet’s urinary tract. They are usually made up of minerals and other substances found in your pet’s urine.

Guinea pigs can form urinary stones when they eat food with minerals (like calcium) that make stones. These minerals end up in their urine. If the concentration of these minerals in their urine is too high, they can form crystals.

Sometimes, the crystals that form in your guinea pig’s urine will clump together to form bladder or kidney stones. In most cases, these stones will not cause any problems. However, in some cases, the stones can grow large enough to block your pet’s urinary tract.

What Should You Not Buy For A Guinea Pig? 

You shouldn’t buy a guinea pig any processed food. That includes pellets, seeds, nuts, and crackers – to mention but a few. These foods are high in salt, sugar, and other unhealthy ingredients.

They can also contain harmful chemicals that can be dangerous for your guinea pig. So, it’s best to avoid them altogether. In fact, unless your vet confirms something to be safe for your guinea pig, it’s always best to steer clear of it.

Final Thoughts

Guinea pigs need sodium in their diet. But they usually get enough from their food, so they don’t need a salt lick or mineral wheel. If they have too much sodium in their diet, it can harm their health.

You don’t need to give your little friends supplements, unless it has a medical condition that needs them. If you give your pig a healthy and balanced diet, everything else will fall into place.
