Miralax Dosage Chart for Cats: Risks, Side Effects, Dosage, and More

Constipation happens. Sometimes, it’s a prescription medication that has your kitty all backed up. Sometimes it’s an illness like kidney disease and sometimes it’s diabetes. Other times hyperthyroidism could be the culprit. The point is that sometimes your cat has trouble going potty, and Miralax is an over-the-counter solution that could help. Learn about the Miralax dosage for cats as well as any risks and side effects associated with its administration.

When Do Cats Need Miralax?

A cat might need Miralax if they are having trouble with bowel movements. You might have noticed that your cat is going to the litter box but not emptying its bowels. They might try to dig, they might whine, and they may even lose their energy. With a full belly, it’s hard to keep an appetite so you may notice that there is a loss of appetite as well.

If there is vomiting, it could also be a sign of constipation. That’s where Miralax comes in. This is a laxative that helps to soften your cat’s stool so that it can pass more easily. You can administer it as a powder either in their drinking water or mixed in with their preferred food.

Side Effects of Miralax on Cats

Vets may recommend you purchase over-the-counter laxatives for your cat, or they may suggest a prescription option. However, you should not administer a laxative unless your veterinarian recommends it. Miralax does not have any flavor so your cat won’t pick up on anything different, but it could have some side effects. The main side effect is dehydration. The way that Miralax works is by keeping water inside your cat’s gut. What this means is that the rest of your cat’s body isn’t absorbing any water.

When administering Miralax, it’s vital that you ensure proper hydration. Adding broth, encouraging drinking with a fountain, or even adding water to their wet food can help increase their hydration while they take Miralax. Miralax is a laxative, after all. But that might result in stool that’s a bit too loose and watery: diarrhea.

Signs of Miralax Overdose/Allergies in Cats

If you’ve ever taken a laxative, you probably know that a little too much can cause cramping, nausea, vomiting, and the kind of diarrhea that’s a bit explosive. The good thing about Miralax is that it’s not deadly. However, you should refrain from administering too much at a time.

Be sure to follow your veterinarian’s recommendations when administering Miralax and let the laxative do its work. If your cat’s stool is much too impacted, they may require an enema. Miralax isn’t the end-all-be-all treatment for constipation in cats. Too much or long-term use of Miralax can not only cause dehydration but can also lead to high potassium levels and low sodium levels, which can lead to complications.

Risks To Consider

Cats usually tolerate Miralax well and it’s considered safe but there are some risks. None of the risks are life-threatening but they are worth mentioning. Along with dehydration and diarrhea, your cat may experience increased flatulence and uncomfortable cramping. In high doses, it just makes your cat feel worse. Be sure to communicate with your veterinarian if you notice that Miralax isn’t working as intended. Your cat may need a different type of treatment.

When Is Miralax Not An Option For Your Cat?

If your cat has too much impacted stool, your veterinarian may recommend an enema. At this point, Miralax may not be as effective as it could be with a milder case of constipation. Make sure you connect with your vet to make the right decision for your kitty’s well-being.

How to Treat Miralax Overdose in Cats

Although Miralax is generally safe and doesn’t pose any life-threatening risks, if you notice that your cat is in distress after administration of Miralax, connect with your veterinarian right away. You can’t know exactly what’s going on in your feline friend’s body unless your veterinarian takes a look. It could be dehydration, or it could be something else. It’s always best to rush your kitty to the vet or your nearest animal hospital if you are concerned about their reaction to the administration of any laxative or medication.
