I got rid of my carpets for just that reason. When we pulled the old carpet up in a used trailer we bought the bottom of it was stained with what I suppose was animal wee-wee. And the floor was full of really fine silt that the vacuums just can't pull out of it. I had asthma a lot and we got tile put down and it really help with the allergies.
My cholesterol was a bit elevated this last time, but according to all the Low carb advocates it will come down even eating more meats. We'll see with the next test which will be in Oct.
Have a great Sunday!!!
