Cats, Toxoplasmosis and Pregnancy

Many well meaning people have told me that once I get pregnant I will (1) have to stop cleaning the litter box and (2) possibly get rid of my cats.

Neither need to happen nor are going to happen.  First of all, it would not work with our lives and the fact K travels Monday-Thursday and second of all, these concerns about toxoplasmosis don't really apply for women with INDOOR CATS. 

Read on.....

If you're expecting a baby, you may have heard of toxoplasmosis because it can cause serious birth defects. A woman who acquires toxoplasmosis during pregnancy can transmit the infection to her unborn child. And a congenital toxoplasmosis infection in utero can lead to miscarriage or an array of malformations at birth. Because one of the ways to become infected is through contact with the infected feces of cats, many pregnant women try to lower their risk of acquiring toxoplasmosis by giving their cat away or putting the cat outside.

Thankfully, you can easily avoid contracting toxoplasmosis from cat feces without giving up your beloved feline "baby." Cats acquire toxoplasmosis from eating contaminated raw meat, birds, mice, or soil. While cats are the only species of animal to shed the infectious stage in their feces, other animals can disseminate toxoplasmosis if their infected meat is eaten without proper cooking.

Likelihood of Contracting Toxoplasmosis

Because it's difficult for cats to transmit toxoplasmosis directly to their caregivers, a pregnant woman is generally unlikely to contract the disease from her pet cat. Several factors keep the chance of such transmission low.

First of all, only cats who ingest tissue cysts acquire infection. Within the feline population, this would be limited to outdoor cats who hunt and eat rodents, as well as cats who are fed raw meat by their owners. In addition, only after a cat is first exposed to T. gondii does he typically excrete oocysts, and he does so for only two weeks. An outdoor hunting cat is often exposed to the disease as a kitten and is, therefore, less likely to transmit the infection as he ages.

Secondly, because oocysts become infective only after one to five days, exposure to the disease is unlikely as long as the cat's litter box is changed daily.

Finally, since oocysts are transmitted by ingestion, in order to contract toxoplasmosis, a woman would have to make contact with contaminated feces in the litter box and then, without washing her hands, touch her mouth or otherwise transmit the contaminated fecal matter to her digestive system.

Reducing Your Risk of Toxoplasmosis

Even though it is unlikely that a woman will contract toxoplasmosis from her cat, it's a good idea to err on the side of caution. The following recommendations will help cat owners expecting a child to reduce their risk of contracting toxoplasmosis.

  • Avoid undercooked meat.
  • Wash all uncooked vegetables thoroughly.
  • Be certain to wash all cutting boards and utensils that may have come in contact with meat before using them to prepare other foods.
  • Wear gloves when working in soil. If gloves are not worn, hands need to be washed thoroughly following soil contact.
  • Ask a spouse, friend, or neighbor to help out with litter box duties while you're pregnant.
  • If you don't have help to keep the litter box clean, wear rubber gloves when changing the litter and thoroughly wash your hands afterwards.
  • Change your cat's litter on a daily basis.

Hey. :D

Thanks for your comment. A lot.

And I agree with you, but on the other hand, we live in a rental house, and the guy before us had some trouble with rodents (though we haven't seen any) so we're playing it safe. (It helps that I have bad knees, and the litter box is in the basement. Heh.)

But my co-worker (who's in the hospital RIGHT NOW possibly having her baby) lives alone, and cleaned it with no problem, but she wore gloves and a dust mask for "just in case."
