Cats are wonderful animals, but many owners complain about their smelly litter boxes. While many brands claim to eliminate the odor, some use a fragrance that smells almost as bad and might cause your pet to stop using it. One popular remedy is baking soda, which is fragrance-free and great at absorbing odors, but is it safe for cats?

The answer is no; baking soda should not be the first choice when trying to solve a smelly litter box. Keep reading to learn why adding baking soda to your cat’s litter box should be avoided.

The 4 Potential Risks of Using Baking Soda in Cat Litter

Baking soda is commonly used in baking as a rising agent in muffins, cupcakes, and cookies. Some people also use it to reduce food odors in their fridges. This is probably why people think (and hope!) that baking soda would take the edge off a pungent little box. But there are several reasons why this is not a safe idea.

1. Allergies or Sensitivities

Some cats may be allergic or sensitive to baking soda. Watch for adverse reactions in your cat, such as sneezing or excessive grooming, and discontinue use if you notice any.

2. Ingestion Risk

Cats are known for their curiosity and may ingest small amounts of litter. While baking soda is safe in small quantities, eating large amounts can be harmful, so discontinue use if you notice your cat using it as a snack. Plus, there is insufficient research on the long-term effects of ingesting baking soda.


3. Respiratory Issues

Baking soda dust can become airborne when your cat digs in the litter box, irritating your cat’s respiratory system. Always maintain good ventilation in the litter box area, which will also help disperse fumes.

4. Litter Type Compatibility

Some types of cat litter may not work well with baking soda. For example, clumping litter with moisture-absorbing properties may not benefit from additional baking soda.

The 3 Alternatives to Baking Soda

1. Regular Cleaning

Don’t want the litter box smelling? Scoop your cat’s litter box daily, and replace the litter regularly to prevent odors from building up. Being diligent about cleaning is the most effective way to keep odors away.


2. Choose High-Quality Litter

Invest in a high-quality cat litter designed for odor control and moisture absorption. Many premium litters use special ingredients that work to neutralize odors effectively.


3. Ventilation

Maintain good ventilation in the area where the litter box is in order to reduce odor concentration.

Conclusion

Baking soda might seem like a quick solution to litter box odors, but it is not the best solution for that problem. It is unclear how cats will react to baking soda if it is ingested. We do not want to put our cats at risk over something that can be solved with everyday cleaning. It won’t be pleasant, but your home won’t have a lingering odor. And a clean litter box is healthier for your cat!
