My stepdaughter, who lives with us, goes to her mom's every other weekend. They have a cat, by the way. After the past two visits, she has come home with bug bites. This last time there were so many I was concerned it was something other than bug bites, so I took her to a dermatologist. The prognosis: flea bites. Now of course it's not us. Zoe get's Frontline Plus every month like clock work. Plus...she doesn't have bites here- it's always after a visit to her mother's. My husband called his ex and informed her that her daughter is covered in welts and that she needs to get her cat dipped and home de-flea'd. Her response "We don't have fleas. They must be from your dog, so it's not my problem". I could strangle her.
