i have two cats and a dog and i followed the whole 'no cleaning of litter tray' (not that hard to pass up! ). it was never suggested that my furbabies had to exit the premises during my pregnancy.
like with many things in pregnancy just have extra attention to the details and avoid the poo...

i also used a bit of caution when in the garden as my fav garden bed was also their fav toilet...ewww.

The GP went OTT i think. maybe she doesnt like cats! my kitties also hang out in the house most of the time and share the bed. absolutely no dramas there.

please keep the kitty!
