Does revolution tend to not work sometimes for fleas ? My cats have been treated for almost 2 weeks now and I keep finding a lot of fleas on them live. I don’t know what else I could do....

You are doing a good job. Keep up with the vacuuming and I would use a flea comb on them daily to catch and kill any live fleas. You can dip the comb in a dilute mixture of dawn dish soap and water. Often the Revolution will kill the fleas but it takes time for them all to die off. After a few weeks all of the fleas should be gone. Continue the Revolution monthly and they shouldn’t get another infestation. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for your cats.
