I was wondering what was better for cats, bio spot or frontline?  My house was infested with fleas (I rent and it was the previous owner's fault)  and even though I had an exterminator in here last week, my cats had a flea bath but both the house and cats are still crawling with fleas.  We're moving to another place in a couple of weeks and I'm so afraid of carrying the fleas with us.  Any suggestions?  
Thanks, Tina
