Part 2. Why Is the Litter Box Stinky

The cat’s urine and poops are culprits of the smelly litter box. Aside from that, the litter box will contribute to long-lasting odor.

Cats’ pee smells stronger than other animals because it contains a high level of uric acid and urea, which can last in the litter box for years 😂

Note: If you notice a pungent odor coming from litter box, it may be a sign of health issues, such as a urinary tract infection. In that case, you should take your cat to the vet.

Cats are carnivores. Their food often contains rich proteins. The high protein content of your cat's diet causes it to defecate foul-smelling stool.

Hint: Drinking plenty of water is beneficial to the cat's diet and helps to reduce the waste smell.

Bitter boxes should not have plastic linings, since they can absorb urine and leak it into the box, causing the odor to last longer.

Part 3. Tips to Get Rid of Litter Box Odor

Having cats or rabbits does not imply that their litter box must stink up the entire house. The stench of a litter box can be controlled with the following simple tips, keeping your home smelling fresh 24/7.

Scoop litter boxes daily. The best way to reduce litter box odors is to scoop the stinky stuff (cat's poops) at least once a day (preferably twice), preventing odors from accumulating.

Replace all the litter and clean the box thoroughly every two weeks. Your litter will absorb the smell of the pee and poop in the box. You should change it every two weeks to avoid the unpleasant odor from accumulating.

Replace the boxes once a year. As your cat buries their waste, the boxes may become scratched. These scratches are ideal place for bacteria to hide and reproduce.

Change your cat’s diet. If your cat's waste smells worse than usual, it could be a dietary problem. Their food may contain something that bothers their digestive tract. Changing your cat’s diet may reduce the amount of odor they produce.

Add more well-sized boxes. If you have more than 2 cats, you should make sure that each cat has a well-sized litter box because cats don’t like to go where other cats have gone.

Use pet odor eliminators in the litter box. You can spray the litter deodorizer to neutralize the ammonia odor in your cat litter. Deodorizers are usually made of baking soda or enzymes. You can spray them on top of the litter to mask odors.

Use baking soda. Baking soda can absorb odors and keep the litter box odor-free. You can add a small amount of baking soda to the bottom of the litter box or simply place it near the litter box to absorb odors.

Put your litter box in a well-ventilated area. Moving the litter box to an area with better ventilation will help the odors disperse before they can make your litter box too smelly.
