My cat had fleas pretty bad (he is indoor/outdoor but prefers to be out most of the time and rome around the woods in my backyard)....so before I went to get him frontline I brought him to the vet for a bath and flea dip so as to get rid of them first. Then they told me that I would have to wait two weeks after the flea dip before I could put the frontline on him....so I waited....and now it is two weeks later but he has a ton of fleas all over again! WTF! So here is my question....do I just put the frontline on him and expect that to get rid of all the fleas? (btw....how does that stuff work??????) or do I need to do something else to get rid of the fleas BEFORE putting on the frontline? ARG I hate fleas and ticks!!!!!! My poor baby is itching like crazy....what do I do?
