We have 3 cats and they all have fleas. We are seeing fleas on our bed and blankets. We tried putting this medicine on their necks that we bought at the store but it didn't work. We bathed each one last night in flea shampoo (that was pure hell) then used a flea comb until they wouldn't sit still anymore. They are still itching like crazy. My next step is bagging up everything and washing everything then trying the flea medicine again. Anyone have any tips on how to get rid of them?
