Can Cats Eat Vaseline? Vet-Reviewed Health Facts
Updated on
No home medicine cabinet is complete without the legendary tub of Vaseline. Its uses in the home and on the person seem to be endless! But although it is proven to be safe for many personal human benefits, is it safe for our pets?
Generally, Vaseline (also called petroleum jelly, petrolatum, or white soft paraffin) is not toxic if ingested in controlled amounts. In fact, some hairball products contain petrolatum in their ingredient list. There will be some risks associated with a cat eating Vaseline depending on multiple factors, including the type of Vaseline, your cat’s general health and age, and how the Vaseline is administered.
Read on to delve deeper into this controversial topic so you can make all the best choices for keeping your cat happy and healthy.
Is Vaseline Safe for Cats to Eat?
While Vaseline is a super common household product, how many of us actually know what’s in it?
Vaseline is a type of hydrocarbon (a substance made up primarily of carbon and hydrogen) derived from petroleum distillation. Therefore, the main ingredient of Vaseline is actually petroleum.
Vaseline has a high viscosity, which means it is very thick, and therefore the risks linked to aspiration are very low compared to thinner paraffin products. The main hazard would be the product getting into your cat’s lungs (aspiration pneumonia), which can happen with liquid Vaseline.1
The petroleum in Vaseline is a by-product that is commonly used in human cosmetics and skin products. It has been proven to be safe for external human use.2 However, the risks of chronic exposure in women are being investigated.3 Its chemical composition is helpful as an “occlusive” or, simply put, a moisture barrier.4 It doesn’t actually add any moisture as it does not absorb into surfaces but instead forms an impenetrable protective layer.
Vaseline has no nutritional value and it is minimally absorbed by the gut. Vaseline given by mouth is used as a laxative because it lubricates stools and the intestinal lining. It is considered safe for cats if taken in limited amounts and in the right formulation. You should never attempt to give liquid paraffin to your cat because the risk of aspiration pneumonia is very high. Paraffin as a laxative can also be given rectally if indicated by your vet. Using this route, the risk of aspiration is minimal. However, the risk of digestive upset is still present if the dose is not adequate.
Vaseline as a Treatment for Hairballs
If you’ve owned furry friends for an extended period, then you will know there’s a lovely time of year when your home will be inundated with cat hair. Cats shed their coat twice a year, during spring as they lose their winter coat in preparation for summer, and in fall when they lose their summer outfit to fluff up for winter.
Cats can be prone to getting hairballs any time of the year, but these times of heavy shedding will increase that risk as there is simply a lot more fur about for them to ingest. Smaller amounts of ingested hair will often pass through their digestive tract without a hitch. Still, more significant amounts can cause irritation and conglomerate together as a hairball.
Usually, hairballs will not get too far and be regurgitated back up. But on occasion, they will make their way past the stomach and into the intestines, where they can cause some severe issues if they become impacted and cause a blockage.
While there are some ways to avoid excess hair ingestion and reduce the risk of hairballs there is also a range of internal treatments for further down the line. Vaseline as a dietary additive is one of them. Recommended by a few vets, Vaseline can assist by acting as a digestive lubricant. Its oily and barrier-like properties can help impacted hairballs move along the digestive tract and either be passed through the other end or successfully vomited back up.
It is also featured as a home remedy for constipation in cats for these same reasons. Vaseline is not the only product with this effect; natural oils can also offer the same benefit. While there seems to be some ground that Vaseline can be an effective treatment for cat hairballs, you should exercise some natural caution as an owner.
Risks of Vaseline for Your Cat
Diarrhea
Along with the benefits of a digestive lubricant, there come some risks. Given its laxative properties, if too much Vaseline is given, your cat is at risk of developing diarrhea, and prolonged diarrhea can cause dehydration and anal irritation.
One accidental consumption of Vaseline or one day of consumption as a hairball supplement should not have any extreme ill effects on a healthy cat. Exceptions will be cats that are already ill in some way. For example, cats with chronic kidney problems that might already be slightly dehydrated can get very sick if they lose further body fluids.
Longer-term Vaseline treatment can be especially harmful to elderly cats or kittens who will lose their body condition a lot quicker than a healthy adult.
Aspiration Harm
As a mineral oil, there are also some associated risks regarding aspiration of liquid Vaseline. Cats are particularly susceptible to aspiration pneumonia. This occurs when this oily substance gets to your cat’s lungs rather than their digestive system. It creates a serious problem that can be fatal.
If using Vaseline as an oral supplement for your cat’s hairballs, then ensure that you never force-feed it into their mouths. If you ever use it on your cat’s skin, make sure you apply a very thin layer and try to avoid your cat licking it off. However, do not panic if it is a one-off situation as this should not harm your cat.
Conclusion: Always Consult Your Vet
Suppose your cat has accidentally gotten into your Vaseline tub. In that case, there is not too much to worry about—just keep an eye out for irritation! If you are tossing up the use of Vaseline for other purposes such as external treatments or a hairball remedy, then we strongly advise you to contact your vet for professional advice.
As you can see, there is a range of things to consider for your cat’s health with using Vaseline orally. It’s no wonder it’s contested both between cat owners and veterinarians alike. While some home remedies may be suitable for your cat, you should always consult your vet before using any!
