What is a zoonotic disease?
Zoonotic disease or zoonoses are terms used to describe an infection or disease that can be transmitted from an animal to a human being.
Am I at risk for contracting a zoonotic disease from my cat?
Current evidence supports the fact that pets pose a minimal zoonotic risk to their human companions. Cats kept indoors are exposed to fewer diseases that could be transmitted to humans. Your risk may be slightly higher if you fall into one of the following groups:
If you fall into one of these categories, it doesn't mean you have to give up your pet! It simply means that you should take some basic precautions such as not contacting your cat's feces directly, monitoring for any signs of illness in your cat and washing your hands after extensive handling of your cat.
It is important to keep in mind that numerous studies prove that the benefits of having a pet far outweigh the risks. Sharing your home with a pet is often just what your doctor ordered!
What are the most common infections I could contract from an animal?
While the risk of contracting any of these illnesses is low, here is a list of common zoonotic diseases. Note that many of these infections are the result of ingesting undercooked meat, fish and poultry or involve exotic animals and travel.
Ciguatera Fish Poisoning
Colorado Tick Fever
Domoic Acid Poisoning (Amnesic Shellfish
Echinococcosis (Hydatid Disease)
Encephalitis (specify etiology)
Escherichia coli 0157:H7 Infection
Food borne disease
| Lymphocytic Choriomeningitis
Paralytic Shellfish Poisoning
Plague, Human or Animal
Rabies, Human or Animal
Rocky Mountain Spotted Fever
Salmonellosis (Other than Typhoid Fever)
Scombroid Fish Poisoning
Swimmer's Itch (Schistosomal Dermatitis)
Viral Hemorrhagic Fevers (e.g., Crimean-Congo, Ebola, Lassa and Marburg viruses)

What can I do to reduce the risk of contracting a disease from my cat?
Proper litterbox cleaning is the most effective way to reduce the risk of contracting a disease from your cat. Here are simple guidelines you should follow if you fall into a risk category:
Place your litterbox away from the kitchen and other areas where you prepare or store food
If possible, have someone who is not at risk clean the litterbox. Otherwise, clean the litterbox daily, since the organism that causes Toxoplasmosis takes at least twenty-four hours to become infectious.
Use disposable litterbox liners and change them each time you clean the litterbox.
Don't dump the litter. If you dump litter, you could potentially aerosolize an infectious agent and inhale it. Be sure to slowly pour the litter or simply twist and close the litterbox liner.
Clean the litterbox at least twice a month with hot water, letting the hot water stand in the box for at least five minutes. This simple cleaning technique will kill the Toxoplasma organism.
Wear disposable gloves and discard them after each use. Thoroughly wash your hands after cleaning the litterbox.
In addition to Toxoplasmosis, is there anything else I can get from my cat's feces?
Cats can occasionally be the source for intestinal ailments including some bacterial infections (Salmonella and Campylobacter) and some intestinal parasites (Giardia, Cryptosporidium, and roundworms.) These diseases can be spread to people by direct contact with the feces of an infected cat or by contact with soil that has been contaminated by the feces of an infected cat. Many other animals also carry these infections. Salmonella and Campylobacter are most often spread through undercooked meat or improperly prepared food.
How do I know if my cat has a zoonotic disease?
Cats that are carrying one of these infections will sometimes, but not always, have loose stools or diarrhea. All newly acquired cats are at a higher risk and should have their feces tested by your veterinarian as soon as possible.
What will happen if I get one of these diseases?
This group of bacterial and parasitic infections will usually only produce temporary symptoms in someone with a healthy immune system. For people who are immunocompromised, however, these infections can be life-threatening. Ringworm can be a stubborn infection but is curable with persistent treatment.
How can I prevent my cat from getting bacterial infections and intestinal parasites?
Preventing these diseases is easier than you think. Somesimple guidelines to keep your cat healthy are:
