Cat Litterbox Spray to Remove Smell

What to Consider When Purchasing Cat Litter

Buying litter for your cats depends on how many cats you have, whether you need one box or more, and which types of litter you require. Many types of litter are available, like clay, silica-gel, pine, and others.

Some people prefer scented litter, as they can function as cat deodorizers. However, many cats might not like the smell of scented litter.

How Many Cats You Have

In multi-cat homes, it might take a while to understand what types of litter work best. Since there are so many options available and cats tend to be choosy, it might take some trial and error to figure out which types of litter are best suited for your cats.

How Many Litterboxes are in the House

If you have more than one cat, it is always a good idea to have more than one litter box at home. This way, there won’t be crowding in a single box. This also prevents an overpowering smell and excessive use of one litter box.

However, sometimes even one cat can be fussy and need more than one box. Placing the boxes throughout the house is a good idea in this case.

Location of the Litterboxes in the House

Ideally, litterboxes need to be placed throughout the house in different locations. Cats like to do their business in private areas, and placing any litterbox out of the way will help them use the boxes in peace.

It is also important to note that if you have more than one cat, it is preferable to spread the litterboxes in all the different rooms of the house.

What Kind of Litter You Use

Most owners prefer the traditional clay litter, which has a tendency to cake and clump. However, you can try different types to find out which one is preferred by your cats [1].

Ideally, good litter is low-dust, highly absorbent, masks odors, and is easy to clean and maintain.

How to Get Rid of Smelly Cat Litter

Important Features To Consider

Some factors have to be taken into account when choosing the best litter box deodorizer.

A good one is moisture absorbent, masks all unpleasant smells and does not lose potency quickly. There are many forms available- granules, sprays, powders, and more.

Granules mix in with the litter keeping it fresh for a long time. Whereas, sprays are used topically or around the box. Although their potency varies.

Here are few features:

Your Own Allergies to Certain Ingredients

Some ingredients used in deodorizers can cause allergies. Selecting deodorizers with natural ingredients like baking soda can help avoid this.

Many elements also act as irritants for pets and can make them averse to using the litterbox. The solution for this is to choose deodorizers that are safe and non-toxic for animals.

Moisture Absorbency

Moisture absorbent properties in deodorizers are vital to absorb urine. This also increases the masking of odor and ease of cleaning. Zeolite is one of the commonly used components as it is highly absorbent and effective.

Moisture absorbency also helps prevent bacterial or fungal growth in litterboxes as bacteria and fungi thrive in damp spots.

Deodorizing Strength

Buying a product with an overpowering scent is not recommended as it can act as an irritant for your cat, besides triggering allergies. Nevertheless, it is important to get deodorizers potent enough to mask the odors of a litterbox.

If you prefer, you can even use an unscented product that works well without being too intense for your liking.

Duration of Deodorizing Effect

Deodorizers need to last long, especially in multi-cat homes. Recurrent usage of the box can result in overwhelming smells, and a product with weak potency will not mask any odor properly.

If you have only one cat, a combination of regular cleaning and a good deodorizing agent can help augment the deodorizing effect.

What Are Natural Options to Litter Deodorizers?

Several natural solutions are available for those looking to combat odor from cat waste. Baking soda, charcoal filters, and regular upkeep are just a few of the ways you can control odor from cat waste.

Natural options are a good choice for fussy pets, allergic owners, or those who do not want to use scented odor control methods.

Here are a few more natural options:

Baking Soda

Baking soda is a great natural alternative for deodorizers. A thin layer of baking soda at the bottom of the box will help absorb any foul odor.

Baking soda has the additional advantage of being cat-friendly. It will not repel your cats due to it being odorless. A little goes a long way, and even better, if you use baking soda you will not have to worry about running out of deodorizers.

Charcoal Filters

Charcoal filters come built into some litterboxes to combat odor and mask unpleasant smells. This is an easy way to keep your cat’s box fresh without adding anything extra.

Purchasing a box with charcoal filters also makes cleaning convenient, and reduces clumping and caking.

Regular Cleaning

Often, the issue is irregular cleaning, especially for houses with more than one cat. To remedy this, set a schedule for cleaning out your cats’ litterboxes. This prevents crowding and gets rid of lasting smells.

Dirty litterboxes can also make your cats anxious and unwilling to use the box.
