If you live with a cat, baking soda is probably already in your home. It is commonly used for cleaning, deodorizing carpets, or controlling odors in litter boxes. Because it is often described as natural, many cat owners assume it must be safe. The reality is more nuanced.
Baking soda is not classified as a poison for cats, but it is also not harmless. Whether it is safe depends entirely on how a cat is exposed to it.

Is Baking Soda Safe for Cats
Veterinary sources do not classify baking soda as a toxic substance like antifreeze or certain plants. Small accidental exposure is unlikely to cause life threatening poisoning.
However, baking soda is sodium bicarbonate, an alkaline salt. Cats are much smaller than humans and far more sensitive to changes in electrolytes and acidity. Because of that, baking soda can still cause digestive upset, irritation, or more serious symptoms if a cat eats it or comes into repeated contact with it.
So while baking soda is not deadly in tiny amounts, it should not be freely used around cats without care.
Why Baking Soda Can Be Risky for Cats
Cats groom themselves constantly. Anything that touches their fur or paws is likely to be ingested later. Baking soda that seems harmless on a surface can end up inside a cat’s body.
Veterinary pharmacology sources explain that ingestion of sodium bicarbonate can disrupt acid base balance and electrolyte levels in animals with small body weight. Even amounts that seem minor to humans may be significant for cats.
Cat owners often assume that everyday household items are harmless, especially when they are described as natural. However, just like some common houseplants like aloe vera or even decorative flowers like carnations, baking soda can still cause problems for cats if they come into direct contact with it.
Different Ways Cats Come Into Contact With Baking Soda
Understanding how exposure happens is more important than the baking soda itself.
Accidental Eating or Licking
Cats may lick baking soda from floors, carpets, or countertops. They may also step in it and ingest it while grooming.
Veterinary reports note that ingestion can lead to drooling, stomach irritation, vomiting, diarrhea, gas, and lethargy. In larger amounts, sodium imbalance may cause tremors or weakness. These reactions are usually mild but should not be ignored.
Smelling Baking Soda During Cleaning
Baking soda does not release toxic fumes. However, cats have an extremely sensitive sense of smell. Strong odors can cause sneezing, avoidance behavior, or visible stress.
Good ventilation and keeping cats out of the area during cleaning usually prevents this discomfort.
Skin Fur and Paw Contact
Direct contact with baking soda can irritate a cat’s skin or paws, especially if it is damp. Because cats groom afterward, this increases the risk of ingestion.
This is why veterinary sources advise against applying baking soda directly to a cat’s body.
Baking Soda in Cat Litter Boxes
One of the most common questions is whether baking soda can be added to cat litter to control odors.
Veterinary guidance does not recommend adding loose baking soda directly to a litter box. Cats may inhale or ingest it, or it may cling to their paws and fur.
Some commercial litters contain baking soda, but these products use controlled amounts and specific formulations designed for pet safety. This is very different from pouring household baking soda into a litter box.
Symptoms of Baking Soda Exposure in Cats
Most reactions are mild, but symptoms can include:
- Vomiting or diarrhea
- Drooling
- Lethargy
- Increased thirst
- Abdominal discomfort
More serious symptoms such as muscle tremors, confusion, or weakness require immediate veterinary attention.
What To Do If a Cat Eats Baking Soda
If a cat consumes a small amount and shows no symptoms, monitoring may be sufficient. Do not induce vomiting unless directed by a veterinarian.
If symptoms appear, or if you suspect a larger ingestion, contact your veterinarian or an animal poison helpline promptly. Early advice can prevent complications.
Can Baking Soda Be Used Safely Around Cats
Baking soda can be used cautiously for household cleaning if basic precautions are followed.
Dilution with water, thorough rinsing of surfaces, allowing floors to dry completely, and keeping cats away during cleaning significantly reduces risk.

Why Baking Soda Should Not Be Used as a Home Remedy for Cats
Online advice often promotes baking soda for fleas, skin issues, or odors. Veterinary sources do not support these uses.
Applying baking soda directly to a cat’s skin or coat increases irritation and ingestion risk. Proven veterinary treatments are always safer and more effective.
Safer Alternatives in Cat Homes
If odor control or cleaning is the goal, pet safe cleaning products and litters designed specifically for cats are a better choice. These products are formulated to reduce irritation and accidental ingestion risks.
Final Thoughts From a Veterinary Perspective
Baking soda is not a poison, but it is also not risk free for cats. Most problems occur through ingestion or repeated contact, not from brief exposure.
Many household risks for cats are not obvious at first glance. Products and plants that seem safe to people, including things like decorative flowers such as carnations, often require extra caution when cats share the same space.
In my experience working with cat health and safety topics, issues usually arise when household products are used casually without considering how cats interact with their environment. Prevention and informed use remain the safest approach.
