is it true that cats carry....

Hi there...what you may have heard about is the parasite toxoplasmosis gondii (T Gondii). all mammals can be carriers of this parasite. T. Gondii comes from various sources such as uncooked/raw meat, uncleansed fruits and vegetables, unpasterized milk, ground soil, etc. T Gondii doesn't cause loss of fertility rather it affects the unborn fetus in a pregant woman which can result in a birth defects, miscarriage, premature birth, still birth, etc. Ideally, anyone owning a cat should ask a spouse clean the litter box or wear mask and gloves if doing this themselves since cat feces can contain the T. Gondii parasite. Here's a web article about T. Gondii: http://www.peteducation.com/article.cfm?cls=1&cat=1359&articleid=770

I dont know how true this is but I know alot of women who have become pregnant and do own a cat or two. I think its more of a wives tale.

I was told during my pregnancy to avoid changing the cat boxes. The cats feces contains some kind of bacteria that causes Toxemia. Toxmemia can cause problems with the babies health as well as the mothers. I have not read anything to suggest this disease would cause fertility. I could be wrong though.

im not sure about that. i had 2 cats when i got pregnant with both my kids. you can get toxoplasmosis from them (which can be very serious), so its recommended to stay away from the litter box during pregnancy. ive also read that baby's born into homes with cats have a lesser chance of developing allergies and asthma.

I don't think so, unless a person is allergic to cats in the first place. Then there might be some problems. That sounds like a good question for a vet or doctor.
