Pet's info: Cat | Domestic Longhair | Female | spayed | 2 years and 7 months old
I noticed on Tuesday that my cat had fleas. Very mildly, around 5 were combed out. She was due her effipro so that was administered. I then combed her again using flea comb and I am concerned that I combed the treatment out. I am still combing out 4 or 5 fleas per day. The whole house has been treated with flea spray as well as regular vacuuming. Could it be that the effipro is just taking some time to work? Or should I administer effipro again? Your help is appreciated

Hello! Thank you for using Petco Pet Education Center, formerly Petcoach! I would not apply another dose at this time. The effipro will not work immediately, you can give a Capstar which will kill all adult fleas on Stella within 30 mins. You can purchase this at any Petco Pet supply stores. This can be given even if the pet is on a monthly preventative. Combing should not have removed the treatment as long as you are applying it correctly, directly on the skin. They put a lot of liquid in those vials, so it's impossible not to get any in the fur. If in 2 weeks you are still finding fleas, you can apply another dose of the effipro. If by next month, the fleas remain a problem you may need to consider changing to another flea preventative. I hope this helps and best of luck to you and Stella!
