i posted today about cynder and his lice. i am using advantage and have been told i need to apply it every 2 weeks for a period of 3-4 months in order to get every life cycle of the lice so it won't have time to lay eggs. I need to know if this is right? last night (monday) he looked ok then once again i saw a live lice on him and applied the advantage. it seems to be killing the live ones but how will i really know when ALL the nits have hatched and been killed by the advantage.. i see that there aren't alot of posts on cat lice,but YES they can get them.. if anyone has any info about this please let me know
