Cats are the most popular pets in the United States. According to the latest version of the U.S. Pet Ownership & Demographics Sourcebook (2002 Edition) there were almost 70 Million pet cats in the United States. Why are cats so popular? There are as many answers to this question as there are cat owners, but the low health risks cats pose to their owners is certainly near the top of this list. Even though the potential health risks cats pose to people are small, it is important that cat owners are aware of these risks and understand how to reduce them.
The majority of all risks stemming from cat ownership are associated with the cat litter box and/or cat feces. There are two categories of risks. The first category contains health risks posed by bacteria and parasites to both cat owners and their cats. The second category contains injuries resulting from an automatic litter box or self cleaning litter box.
Primarily the health problems experienced by cat owners or their cats come from the first category and the most significant of these risks is called Toxoplasmosis. Toxoplasmosis is an infection caused by a tiny parasite called Toxoplasma gondii which can be found in raw or undercooked meat, unwashed fruits and vegetables, dirty cat litter boxes and outdoor soil where cat feces can be found. According to the Center for Disease Control and Prevention (CDC) more than 60 million people in the United States may be infected with the Toxoplasma parasite(1). Fortunately, hairless car for sale very few people ever experience any symptoms because a healthy person’s immune system usually keeps the parasite from causing illness. However, pregnant women and individuals who have compromised immune systems, such as individuals infected with the HIV virus, are at risk and should take precautions to avoid being infected by the parasite. For people in this group a Toxoplasma infection could cause serious health problems to the individual or to a pregnant woman’s unborn child.
Again, most of the 60 million plus American’s infected with Toxoplasmosis parasite will never experience any symptoms. Most of those who do experience symptoms will simply think they have the Flu as the most common symptoms include swollen glands, fever, headache, muscle pain, or a stiff neck. For those in the high risk group, Toxoplasmosis can cause damage to the brain, eyes and internal organs. According to the US Food and Drug Administration, children born with Toxoplasma gondii can suffer from hearing loss, mental retardation, and blindness with some children developing brain or eye problems years after birth(2). The CDC estimates that 400-4000 fetuses are infected with the Toxoplasma gondii parasite each year and as many as 80 infants die from Toxoplasmosis annually(2).
So how does an individual contract Toxoplasmosis? A Toxoplasmosis infection is caused by ingesting the Toxoplasma gondi parasite. Most cat owners are infected with the parasite by accidentally ingesting infected cat feces. This happens when a person touches their mouth after handling a cat litter box, working in a garden or sand box or touching anything that has come in contact with cat feces(3).
People in the high risk group may wonder whether or not they should give up their cat to avoid infection. According to the CDC, it is not necessary for cat lovers to give up their cats, but it is important for them to protect themselves from infections. The USFDA makes the following recommendations for avoiding infections(2):
1) If possible, have someone else change the litter box. If you have to clean it, wear disposable gloves and wash your hands thoroughly with soap and warm water afterwards.
2) Change the litter box daily. The parasite doesn’t become infectious until one to five days after the feces are deposited in the litter box.
3) Wear gloves when gardening in a garden or handling sand from a sandbox because cats may have excreted feces in them. Be sure to wash your hands with soap and warm water afterwards.
