We tried everything for our two cats who spend a lot of time outdoors, and nothing worked until we got these collars. Spot-ons were useless as the devious kitties lick their paws and clean it off their necks, and natural treatments had no effect.
We weren't optimistic about these collars, but since putting the collars on a week ago, no ticks at all and only a few ill-looking fleas!
Price was much cheaper than I could get it here in the UK, and no prescription required - perfect!
Have already placed a second order and will be back for more.
