If you have a cat, you know that one of the least appealing aspects of pet ownership is dealing with their litter box. However, the litter box is one of the most important pieces of equipment in a cat owner’s home, and it’s essential to get every aspect right. That means choosing the right box, mat, and litter for your cat. If you get this combination wrong, it is unpleasant, and the smell can be unbearable.

From sprays and gel beads to powders, multiple deodorizing products on the market are designed to help with unpleasant odor issues. Since there are so many brands of cat litter deodorizers, it is important to do the research to find the best type for your cat.

It is a powder that you sprinkle underneath and on top of the litter, and it is supposed to absorb odors and keep the area smelling fresh. In this article, we look at this product in-depth and see if it lives up to the hype.

Contains Arm & Hammer Baking Soda

Arm & Hammer Baking Soda has a long and storied history. The company has been around for over 150 years and was founded by James A. Church, who developed the process of extracting sodium bicarbonate from brine. The product was an instant success, and Church’s company quickly became the leading producer of baking soda in the United States. Since then, it has continued to be one of the most popular brands of baking soda on the market.

Baking soda is a naturally occurring compound known as sodium bicarbonate and an effective way to neutralize cat pee odors. When it comes into contact with an acidic substance, such as cat pee, it neutralizes the acid and creates a neutral solution. In terms of odors, baking soda acts to neutralize both acidic and basic odors. Baking soda is a mild alkali itself and creates a reaction with the molecules that are responsible for creating those odors, thereby rendering them inactive. When baking soda is present, it neutralizes both acidic and basic odors.

Safely Deodorizes Instantly

The baking soda in Arm & Hammer Cat Litter Deodorizer Powder is a powerful odor absorber. When it comes to removing odors, baking soda is fast-acting and can absorb odors within minutes. This is due to its large surface area, which enables it to quickly and easily absorb odors. Additionally, baking soda is safe and non-toxic when used as directed, making it a great option for those looking for a natural way to remove odors. However, if your cat ingests a lot of baking soda, they may experience vomiting and diarrhea, so make sure you keep the box secure if you have a kitty with an adventurous palate.

Is available in Multiple Sizes

Arm & Hammer Cat Litter Deodorizer Powder is available in multiple sizes: 20 ounces and 30 ounces. It is also available in multipacks. The 20-ounce size is great for single-cat homes, and the 30-ounce size is perfect for homes with multiple felines.

One reason it is not available in bigger sizes is that baking soda is hygroscopic, meaning it absorbs moisture from the air. If it’s exposed to moisture, it can clump and become hard to use. That’s why it’s important to store baking soda in an airtight container in a cool, dry place. If you live in a humid climate or your kitchen is particularly moist, you might want to keep it in the fridge. If your Arm & Hammer Cat Litter Deodorizer Powder has absorbed moisture and clumped together, you can still use it; just break up the clumps first.

Has an Overpowering Scent

When it comes to finding a cat litter deodorizer that actually works, many pet parents turn to Arm & Hammer. The brand’s Cat Litter Deodorizer Powder is a popular choice, but some users find the scent to be overpowering. If you’re looking for a cat litter deodorizer that won’t leave your home smelling like a perfume factory, you may want to try another product. While Arm & Hammer Cat Litter Deodorizer Powder does a great job of masking litter box odors, the fragrance can be too strong for some people.

How is this product different from the Arm & Hammer Baking Soda Double Duty Cat Litter Deodorizer?

You can use either of these deodorizers to refresh your cat’s litter, but in comparison to the Arm & Hammer Baking Soda Double Duty Cat Litter Deodorizer, this product seems to be less effective at combating odors.

Is this powder safe for kittens?

This powder is made with natural ingredients that are safe for kittens and cats of all ages.

Do some cats hate the scent?

This is a product that some cats and their owners love, while others can’t stand. Some cats are more sensitive to smells than others. If you’ve got a cat that is particularly finicky about smells, they might not be a fan of this product.
