If you’ve got a cat at home, you’re well aware of just how much the litter box can be a source of unpleasant odours. In fact, cat droppings, laundry residues and limescale can encourage the growth of bacteria and mold, giving off an unpleasant odor. Fortunately, there are simple, natural solutions to eliminate litter box odors and make your home more pleasant. In this article, we’ll explain where bad litter odors come from, how to get rid of litter odors, which products to use against bad cat litter odors, how to remove litter odors in the home and which litter to choose to avoid odors.
What causes litter box odors?
Litter odors are caused by a number of factors:
- Litter quality: some litters are more or less absorbent, clumping or scented. You need to choose a litter adapted to your cat’s needs and your budget.
- Cleaning frequency: you need to scoop out the cat’s droppings every day, and change the entire litter box about once a week. The box should also be cleaned with soapy water and disinfected regularly.
- Where to place the tray: Place the tray in an airy, dry place, away from heat sources. Avoid placing it near water or food sources, which can attract insects or rodents.
- Your cat’s diet: you need to feed your cat a diet suited to its age, health and activity. Make sure your cat always has access to fresh, clean water.
How to avoid litter box odours?
1. Use good litter
To avoid litter box odors, you need to choose the right litter for your cat. There are different types of litter on the market:
- Mineral litter: this is the most common and least expensive. It’s made of clay granules that absorb liquids and odors. It can be clumping or non-clumping. The agglomerating version forms compact balls with urine, making clean-up easier. The non-clumping version needs to be changed more often.
- Plant-based litter: this is an ecological, biodegradable alternative. It’s made from plant fibers such as wood, corn, hemp or straw. It is highly absorbent and limits the formation of bacteria. It can be flushed down the toilet or composted.
- Silica litter: this is a highly absorbent, deodorizing litter. It’s made up of synthetic crystals that trap liquids and odors. It lasts longer than other types of litter, but is more expensive and dustier.
2. Clean litter regularly
To avoid litter odors, clean litter regularly. Here are a few tips:
- Remove cat droppings daily with a scoop and dispose of them in a closed waste garbage can, or in the toilet if you’re using plant-based litter.
- Change the entire litter box about once a week, or according to the manufacturer’s instructions. Empty the tray, clean it with soapy water and dry it well before refilling it with new litter.
- Disinfect the tray once a month with a suitable product or white vinegar. Rinse well and dry before refilling with new litter.
3. Buy covered litter
To avoid litter odors, you can also opt for a covered litter box. This is a box with a lid and hinged door, which limits the spread of odors in the room. However, you need to make sure your cat accepts this type of litter, which may be perceived as too confined or too dark. Covered litter also needs to be cleaned more often, as it retains more moisture and bacteria.
4. Install a carbon filter
To avoid litter odors, you can also install a carbon filter on the tray. A carbon filter is a device that absorbs odors and noxious gases. It’s usually attached to the lid of the covered litter tray, but there are also models that fit under the litter or in the tray. The charcoal filter must be changed regularly to maintain its effectiveness.
5. Check your cat’s diet
To avoid litter box odors, you should also check your cat’s diet. Certain foods can cause digestive problems or urinary tract infections in cats, which can increase litter box odors. It’s important to feed your cat a diet suited to its age, health and activity level. You should also make sure your cat always has access to fresh, clean water.
Products to combat unpleasant litter box odors
1. Baking soda
Baking soda is a natural, economical product with absorbent and deodorizing properties. It eliminates litter box odors by neutralizing the acids present in cat urine. To use, simply sprinkle a layer of baking soda on the bottom of the litter tray before adding the litter. You can also mix baking soda with white vinegar to form a paste that you can apply to dirty or moldy parts of the litter tray.
2. White vinegar
White vinegar is a natural, versatile product with cleaning, disinfecting and deodorizing properties. It dissolves limescale, descales machines and neutralizes odors. You can pour a glass into the product container or directly into the drum, then run an empty cycle at 60°C or higher. You can also add baking soda to reinforce the vinegar’s effect.
3. Use a cleaner
You can also use a cleaner specially designed to eliminate cat litter odors. This is usually a spray or gel that you spray or spread on the litter box or area. The cleaner contains enzymes or bacteria that break down the organic matter responsible for odors. Leave the product to work for a few minutes, then wipe off with a clean cloth.
4. Use a disinfectant
You can also use a disinfectant to clean and sanitize your cat’s litter box. Disinfectant is a product that eliminates germs and bacteria that can cause infection or illness in you or your cat. It’s important to choose a disinfectant that’s suitable for pets, and that isn’t toxic or irritating to them. You can pour it into the tray after you’ve emptied and washed it, then rinse thoroughly with clean water.
5. Use an odour destroyer
You can also use an odor destroyer to eliminate odors from your cat’s litter box. This product neutralizes odor molecules and releases a pleasant scent. There are different types of odor destroyers, such as sprays, candles, diffusers or granules. You can place them near the litter tray or in the room where the litter is kept. It’s important to choose a pet-friendly odor eliminator that’s not too strong or allergenic.
How can I remove the smell of litter in my home?
If, despite these solutions, you still smell litter in your home, you can try these tips:
- Air your home every day for at least 10 minutes to renew the air and remove odors.
- Use an air purifier or fan to improve air circulation and filter odorous particles.
- Place depolluting plants in your home, such as ivy, palm or ficus. They will absorb toxins and odors and produce oxygen.
- Use natural products to perfume your home, such as essential oils, citrus or spices. You can spray them into the air, place them in bowls or heat them in a pan.
Which litter to choose to avoid odours?
To avoid litter box odours, you also need to choose a litter adapted to your cat and your needs. Here are a few criteria to consider:
- Absorption: choose a litter that absorbs liquids and odors well, to prevent the box from becoming too damp or dirty. Clumping or silica litters are generally more absorbent than mineral or vegetable litters.
- Clumping: choose a litter that forms compact balls with the cat’s urine, to make cleaning and changing the litter easier. Clumping or vegetable litters are generally more clumping than mineral or silica litters.
- Fragrance: choose a litter that has a pleasant scent for you and your cat, without being too strong or too artificial. Vegetable or scented litters are generally more fragrant than mineral or silica litters.
- Dust: choose a litter that doesn’t produce too much dust, to prevent your cat from inhaling harmful particles or soiling your home. Silica or vegetable-based litters are generally less dusty than mineral or clumping litters.
