My three cats have suddenly been invaded by fleas. They were treated with Frontline plus 2 weeks ago, when the fleas came back a few days ago we treated them again. The fleas dont appear to be even slowing down/dying once they are on the cats. If I buy advantage or revolution will it hurt the cats to put it on again so soon? I am going to flea bomb the house but want to help my babies in the meantime

I have seen at least five fleas crawling in her fur since I took her home, did the treatment not work? Or will these fleas die soon because of the chemicals or whatever on her?

i know they are fleas because i picked one off with a tissue and it definitely is a flea because i took a parasite class so i know what they look like at least!

I just moved to Florida a few months ago and I have two cats. I gave them three flea treatments (frontline) over the summer, and was curious if it was still necessary to do over the winter. If not, when should I begin again? Thanks!

He seems to have a flea allergy…he has licked and scratched so much that he has a few bald spots under his chin, behind his head and at the base of his tail
thank you everyone for your advice, I will make sure to get his sores healed first then apply the flea treatment, thanks!

I applied advantage on my 15 lbs cat, and this time it didnt work. I just looked in his fur and found a huge live flea. This thing was a monster, not a baby flea. The advantage was put on 2 weeks ago. My cats badly allergic to fleas.

Should I give him another dose?
