The 6 Health Risks of Keeping a Dirty Litter Box

1. Urinary Tract Infections

When you don’t scoop out your cat’s litter, your beloved kitty may squat directly over top of old urine or feces the next time that they go to eliminate. They may also step in these old excretions. The bacteria in their waste can then travel up your cat’s urethra, leading to a urinary tract infection (UTI). A dirty litter box can cause other health conditions due to the natural fastidiousness of cats; they simply do not want to enter a dirty litter box because it’s gross and makes them feel unclean. Examples of such conditions include Feline idiopathic cystitis (FIC) and feline urethral obstructions (FUO).

Feline bladder stones often form as a result of UTIs and, therefore, are often linked to dirty litter boxes. These stones occur when organic materials accumulate in your cat’s bladder, blocking the urethra and making it difficult and painful for your cat to pee.

Signs of a UTI in cats include:

2. Cat Scratch Disease (CSD)

CSD is a bacterial infection that humans can get from dirty cat litter. It is caused by the Bartonella henselae bacteria and is most often passed to humans via cat bites or scratches; however, CSD can also occur from direct contact with dirty litter boxes.

According to data from the Centers for Disease Control and Prevention, CSD is most common in children under 9 and individuals with weakened immune systems. Those with compromised immune systems are more likely to experience complications from CSD, such as eye infections that can lead to blindness and bacillary angiomatosis, an illness characterized by skin lesions.

Signs of CSD include:

3. Salmonellosis

Like CSD, Salmonella first infects your kitty before spreading to you. Your pet may be asymptomatic, so you might not even know they have the infection.

Signs of salmonellosis include:

Since Salmonella lives in the intestinal tract of animals, it is easy to see how it could be transmitted to you via your cat’s dirty litter. Although Salmonella can be considered normal flora for some cats, certain strains can cause issues in people.

If you need to speak with a vet but can't get to one, head over to PangoVet. It's an online service where you can talk to a vet online and get the advice you need for your pet — all at an affordable price!

4. Overexposure to Ammonia

Your cat’s urine is full of ammonia, which is part of the reason it smells so bad. Cat urine is highly concentrated, so it has a strong odor, leading to eye, nose, and throat irritation and headaches. Long-term ammonia exposure can cause lung irritation, coughing, bronchitis, or pneumonia.

As with CSD, children and individuals with weakened immune systems are more at risk.

5. Roundworms

Your cat’s excrement may be home to several types of parasites. Roundworms can pass from your cat’s feces onto you, causing a host of unfortunate side effects such as diarrhea, nausea, and coughing.

If you believe your kitty has roundworms, visiting the vet is in order. Left untreated, severe infestations of this parasite can cause life-threatening consequences.

6. Toxoplasmosis

Toxoplasmosis is a disease caused by the Toxoplasma gondii parasite. It’s relatively common and is generally mild in cats, but because of its zoonotic potential, all cat owners need to be aware of its health implications.

Signs of toxoplasmosis in humans include:

Final Thoughts

While no cat owner has ever looked forward to cleaning the litter box, it is a necessary evil that you must commit to doing daily. A clean box can not only prevent the above health conditions, but it will also stop your cat from eliminating outside of the box. The cleaner your cat’s litter box is, the happier and healthier you and your pet will be.
