Why Cat Litter Smells Like Ammonia if your cat’s litter box smells bad, it’s likely due to the ammonia in their urine, a result of their evolution as desert animals with highly concentrated pee. While this natural adaptation helps their bodies conserve water, it leads to stronger odors in a domestic setting. With the right maintenance, like frequent cleaning, choosing an effective litter, and monitoring your cat’s habits, you can manage the odor and keep your home smelling fresh. Spayed or neutered cats also tend to have less strong-smelling urine, making them easier to care for.

What Causes Urine Smells Like Ammonia So Bad?
Cat litter often smells like ammonia because your kitty’s pee contains urea, which bacteria break down into ammonia during decomposition. This process, combined with mercaptans—a sulfur compound released over time—creates the characteristic strong, skunky odor. Factors like unneutered males marking territory, unspayed females in heat, or older cats with less efficient kidneys can amplify the smell. To manage it, clean the litter box often, use litter that traps and seals odors, and avoid letting it sit too long, as this prevents gases from building up and keeps your home free from unpleasant smells.
Dealing with Smelly Ammonia Odors from Your Cat’s Litter Box
- Smelly ammonia odor in your cat’s litter box often comes from urine and feces buildup.
- Control odors by scooping diligently every day and doing a complete monthly change.
- Dump old litter, wash the plastic box with warm water, mild soap, and baking soda to neutralize and offset acidic smells from pee.
- Dry thoroughly and refill with new litter for better results.
Choosing the Right Litter
- Not all litters are created equal for controlling odors.
- Opt for absorbent litter with strong clumping power that absorbs urine faster and forms harder clumps.
- Look for natural ingredients like baking soda or pH-neutralizing agents to further neutralize smells.
- If you prefer fragrance, choose a light scent to avoid irritating your cat

How to Get Rid of the Ammonia Smell in the Litter Box
Here are some of these suggestions given below to Get Rid of the Ammonia Smell in the Litter Box.
Teach Your Cat to Toilet Outside
If your cat’s litter box smells strongly of ammonia, teaching them to use a designated outdoor spot can drastically reduce the odor and improve indoor air quality. Gradually move the litter box closer to the door and then outside to ease the transition. Ensure the outdoor spot is safe and clean, avoiding areas prone to ammonia buildup. While this approach reduces the need for frequent cleaning and keeps your home fresher, it may not suit cats with mobility issues or health concerns. Maintaining cleanliness around the litter box is still essential to prevent marking and lingering odors.
Use Plastic Litter Trays, Replace Them Every Year
Replace plastic litter trays every year to prevent odor buildup from scratches that trap bacteria. Even with regular cleaning, worn-out trays can retain smells, turning white in some areas. Prolonged use may discomfort your cat and lead to accidents outside the box. Regular replacement keeps your home fresh and your pet happy.
use an Enzymatic Cleaner
If your cat litter smells like ammonia, an enzymatic cleaner like Simple Solution Extreme Pet Stain and Odour Remover is the ultimate fix. Unlike regular cleaners, it breaks down ammonia at its source using active enzymes, neutralizing odours completely instead of masking them. This powerful solution tackles stubborn pet stains and ensures a fresher, cleaner home.
Scoop the Litter More Often
If your cat litter smells like ammonia, it’s likely due to the bacteria breaking down urea in the litter tray. To keep things fresh and avoid that smelly odor, you’ll need to scoop the box at least twice every day. This simple routine is better for both you and your cats, as it mimics the cleanliness they instinctively prefer. Regular scooping not only helps fix the problem but also keeps the tray from turning into a toilet no one wants to use. Remember, cleaning every other day just isn’t enough—being more consistent will make all the difference.
Use More Than One Litter Box
It may seem counterintuitive, but adding more litter boxes for your cats can greatly reduce the strong smell of concentrated cat pee. Instead of relying on a single box, you should provide the correct number of litter trays, which is typically one per cat, plus one extra. This gives them all the space they need and lowers the chances of waste building up in just one spot. Scoop and clean the litter often, as a well-maintained litter tray is far less likely to develop overpowering odors. By giving your cats options, you use their natural habits to keep things tidy and odor-free!
Conclusion
In conclusion, managing the ammonia smell from cat litter boxes is achievable with a combination of regular cleaning, high-quality litter, and attentiveness to any potential health concerns and use product ARM & HAMMER Cloud Control Clumping Cat Litter for removing ammonia odor.
