Last night I found a live flea on Emily! Could we have brought it home from the cat show?? That seems really unlikely but where would it come from? We can't find any signs of flea dirt or any other fleas - although I have seen Eliot scratching but can't find any evidence on him. Oh well - will take them in to be weighed at 2pm and buy some Advantage for a couple months. We have had only two infestations in the past and I sure do not want a repeat. One flea can turn into hundreds in a few weeks! In the meantime, we are washing all the bedding and have completely vacuumed the hose. I HATE fleas!
