On Sunday my daughter noticed a flea on one of our indoor only cats! I am totally horrified! They never had fleas before! I ran to the pet store and bought a product that goes on the back of their neck, then started vacuuming the carpets and furniture. I think I must have done about 10 loads of laundry - throw rugs, blankets, etc. I even threw away the vac bag when I was done. So I was feeling like I was getting things under control until.... we noticed the cat scratching tonight, and looked and found 2 more fleas! Help! I thought the product I put on the cat would have killed the fleas by now and I am not sure what I should do next. I haven't seen any little critters jumping around, and no one has any flea bites ...yet. What should I do?
