I have been using comfortis for 5 months and it works great!! I just stick it some cheese and she eats it. look up their website there are some precautions but I've never had any problems.
fyi I battled fleas for months before (using frontline) I put them on comfortis and havnt seen one yet. I live in south georgia so fleas are year round
