My cat has fleas on Frontline. Is it safe to switch to Revolution?

Updated On September 23rd, 2025

Pet's info: Cat | American Shorthair | Male | 4 years and 6 months old | 21 lbs

My cat gets frontline plus once a month consistently all year long. No fleas all year till this past friday. This weekend I have remover with flea comb a few live small fleas and flea dirt. His last frontline was sat 9/28/19. Is it safe and beneficial if I start him now ( 10/7/19) on REVOLUTION? We live in nj and he is about 22 pounds. He is an inside outside cat. Also, if results on revolution are the same, can he then be put back into frontline. I'm scared of these chemicals.

It would be best to wait another week before applying Revolution. Unfortunately it seems like Frontline is not a good option anymore as I have been having negative feedback from many clients about its efficacy.
