Will cats eat borax?

Cats are naturally curious animals and may investigate or even taste substances that they shouldn’t. Borax is one such substance that can be dangerous if ingested by cats. Here are the key facts about whether cats will eat borax and what to do if they do.

What is Borax?

Borax, also known as sodium borate, sodium tetraborate, or disodium tetraborate, is a compound made of boron, oxygen, and sodium. It’s a naturally occurring mineral that’s mined from the ground. Borax has been used for a variety of household purposes including as a cleaner, laundry booster, pesticide, and fungicide.

Some common household products that contain borax include:

  • 20 Mule Team Borax laundry detergent
  • Boric acid roach killer
  • Flea powder and carpet treatments

Will Cats Eat Borax?

Cats are unlikely to intentionally eat pure borax. However, they may accidentally ingest it by:

  • Licking their paws or fur after walking on treated surfaces
  • Grooming another pet who has borax residue on their coat
  • Chewing on borax containers or applicators
  • Eating bugs or pests that have ingested borax

Kittens and cats are naturally inclined to put objects in their mouths, so they may nibble on borax out of curiosity. Cats may also walk through spills.

Is Borax Toxic to Cats?

Yes, borax is considered toxic to cats and can cause poisoning if ingested. According to the ASPCA Animal Poison Control Center, the most common symptoms include:

  • Vomiting
  • Diarrhea
  • Loss of appetite
  • Lethargy
  • Tremors and seizures

In severe cases, borax ingestion can cause kidney failure, breathing issues, low heart rate, and death if not treated quickly. The amount needed to cause poisoning depends on the size of the cat and other factors.

Amount of Borax that is Toxic

According to PetMD, the estimated toxic dose of borax for cats is 2.4 to 4.8 grams per kilogram of body weight. This means that a 10 lb cat would only need to ingest around a teaspoon of borax to potentially cause poisoning.

Even small amounts can be harmful, especially if ingested regularly over time. Kittens are at higher risk than adult cats.

Treatment for Borax Poisoning in Cats

If you suspect your cat has ingested borax, contact your veterinarian or the ASPCA Animal Poison Control Center immediately. Treatment may include:

  • Inducing vomiting to remove the borax before it’s absorbed
  • Administering IV fluids to prevent dehydration
  • Medications to control vomiting and neurological symptoms
  • Monitoring kidney function

With prompt veterinary treatment, many cats fully recover from borax poisoning. However, kidney damage or other lasting effects are possible if a large amount was ingested.

Protecting Cats from Borax

To keep curious cats safe, take these precautions when using borax products in your home:

  • Avoid applying borax in areas accessible to pets
  • Carefully sweep up any visible powder or residue
  • Store boxes and applicators out of reach of cats
  • Never leave borax unattended around pets
  • Consider using pet-safe alternatives when possible

Cat-Safe Alternatives to Borax

If you want to avoid exposing your cat to borax, some safer, pet-friendly options include:

  • Baking soda – for cleaning and deodorizing
  • Vinegar – natural disinfectant and cleaning aid
  • Essential oils – some deter insects and rodents
  • Diatomaceous earth – can help control fleas and ants

Check with your vet first before using any product if you have concerns about your pet’s safety.

Conclusion

While not likely, some cats may nibble on or walk through borax out of curiosity. Since borax is highly toxic to cats, even small amounts can cause poisoning. Prevent access to borax products, properly clean up any residue, and contact your vet immediately if ingestion is suspected. With prompt treatment, many cats fully recover. Using cat-friendly alternatives can also help keep your pets safe.
