Pregnancy and Cats

Hello all! My husband and Injust found out we are expecting this past Monday! I am about 5 weeks along! Went for my first doctor visit yesterday and all was great and normal. I am considered a high risk from having 2 miscarriages 12 years ago with my first husband and an ectopic in 2009. All that being said my dr suggests I find new homes for my 4 indoor cats or risk getting toxoplasmosis! How many of you have cats currently and what do you do?
