We were getting ready for a family cookout this past Saturday.  We had about 30 people coming over.  I walked out in the backyard shortly before everyone was to arrive and my dear cat had left the biggest dead rat just lying in the grass.  I freaked out.  My husband picked it up between two sticks and he dropped it four times across the backyard where people would be walking soon.  I was so mad at him for trying to carry it between two sticks.  Now, the yard was contaminated….not just in one spot but in four more.  I didn't know what to do.  I made him pour bleach all over every spot.  I have no idea if this was good enough.  I couldn't even enjoy the company.  My nephew walked up with two liter cokes and dropped them right in the exact spot where the rat was.  I told him to sit them by the door and wash his hands.  Next thing I knew, someone had put them on the kitchen counter.  I was freaked the whole night.  I confessed to my aunt and sister because I just knew someone was going to die from this and it would be my fault.  They told me it was ok.  I tried hard to enjoy the evening, but all I could think about was the rat and how many people had the rat germs on their shoes, etc.  I hate this OCD!!!!!!!!!!
BTW, this is the second rat my cat has caught.  We live in the country.  The last time she left it on the front porch and I wouldn't let my family use the front door for about 3 months even after my husband scrubbed it down.
