Can a dirty litter box make you sick? Yes, living with a dirty litter box can lead to a host of unpleasant illnesses such as these:
Cat Scratch Fever
Just one of the bacterial infections humans can catch from dirty cat litter, Cat Scratch Fever infects about 10,000 people each year, according to the Centers for Disease Control (CDC), and about 500 of those people spend time in the hospital. Children under age nine and people living with weakened immune systems are at a particularly high risk of this disease. You can only get cat scratch fever from a cat, not from another person.
Like Cat Scratch Fever, salmonellosis first infects the cat, which may or may not show symptoms, before getting into the human being during the litter box cleaning process. Symptoms include diarrhea, fever, abdominal cramps, and vomiting. Salmonellosis affects about 200,000 people in the U.S. each year.
Overexposure to Ammonia
Breathing in cat urine can actually make you sick. Cat pee is full of ammonia, a toxic gas that can cause headaches, trigger asthma attacks, and even result in serious respiratory illnesses such as pneumonia. Children, older adults, and people with weak immune systems are at particular risk of illness due to overexposure to ammonia.
Parasites make their home in cat excrement. Roundworms, for instance, can pass from cat poop to humans, causing their new host to experience diarrhea, coughing, weight loss, nausea, and more. If you suspect your cat has roundworms, make an appointment with the vet right away, and be extra careful when cleaning out the box.
Your cat is the one actually staying inside the litter box long enough to conduct business, so it's no surprise that she's likely going to be the first one to get sick. Dirty litter boxes can cause kidney, bladder, and urinary tract diseases in cats. When a kitty squats over a pile of feces, bacteria can travel up the urethra, wreaking havoc all along the way. And since UTIs are often asymptomatic in cats, your kitty could be sick a long time before you know to get treatment for her.
Have you ever visited a public restroom so nasty that just the idea of parking your bare behind on the toilet seat grossed you out? Then you know how your cat feels when he steps inside an unclean litter box.
By nature, cats are fastidious animals who obsess about keeping their fur and paws clean. So the idea of using a filthy restroom is just as repulsive to them as it is to us. Besides, cats have a sense of smell 20 times stronger than a human's so...you can do the math on that one.
Will a cat use a dirty litter box? Maybe once or twice, but cats regularly forced to use a dirty litter box will soon take their business elsewhere — your bed, your laundry hamper, or your couch being top options.
One of the most serious dangers cat litter poses to humans comes from toxoplasmosis. Cats can harbor the toxoplasma gondii parasite and excrete it in their feces. If you touch that feces, which you probably will if the litter box is full, you could become infected. Most people show no symptoms, but a few people will experience something like the flu. And pregnant women can experience miscarriage or stillbirth as a result of toxoplasmosis.
Moldy cat poop doesn't smell good, and the odor will leak throughout the house. A covered box helps a lot, but it doesn't substitute for regular scooping and cleaning. You may not notice the scent yourself after a while, but it's almost guaranteed that your guests, neighbors, or landlord will.
So stay safe and keep your cat's litter box clean. Scoop daily. Change the litter twice a week. Wash the box with soap and warm water weekly. For a more earth-friendly litter box cleaning hack, try mixing vinegar and water instead of using soap. And consider adding a Modkat Odor Filter Kit to keep unpleasant smells to a minimum.
Cleaning the litter box when your eyes, nose, or calendar tells you to is an important part of keeping yourself and your cat in great shape. 🖤🐈
