Some small balm for hypochondriacs who are immediately checking themselves for symptoms:
"only 1% of cats are thought to be infected with T. gondii at any given time"
"Indoor-only cats are far less likely carry the parasite,"
"It's a good idea to scoop cat litterboxes daily, as T. gondii does not become infectious until one to five days after it is shed in feces, according to the CDC."
So if you have indoor-only cats and your litter-boxes aren't featured in an episode of Hoarders, you may be ok.
