hi karen actually why they recommend of not clean the litter bin due to the faeces is due to this:
Toxoplasmosis is an infection you can get from a microscopic parasite called
Toxoplasma gondii. Although the infection generally causes a mild, symptomless illness in people with healthy immune systems, it's risky during pregnancy because the parasite may infect the placenta and your unborn baby.Felines are a natural host for the parasite, and it reproduces in their intestines. A cat may become infected with toxoplasmosis from eating infected prey or undercooked meat, or by drinking unpasteurized milk or contaminated water.
if your cat is not new in your family, has always been an indoor cat etc usually there is nothing to worry.
i have 2 kids and this is the 3rd. my cat has always been an indoor cat and has been with me for the past 15 years and when i was expecting my first, i had done a test, for my cat to see if she is infected toxoplasma just to be sure as she was a stray cat as a kitten.
this is just my personal option to take the test. speak to your doc if you have any concerns on your pet
my family member was worried about the fur and the saliva that may pose reaction to the baby... but my 2 girls has always been around my cat since birth for the past 6 & 9 years. no respiratory issue or allergic issue.
salivia / fur shouldn't affect you during pregnancy if this is not your new pet.
