Ever since moving out into the country we’ve had to be active in protecting the cats when they go outside. Using a tick collar was a mistake; seemed to have some value at first but the effectiveness seemed to run out over a short time unfortunately. After some research I came across Merial Frontline Plus Flea + Tick Control, for Cats and Kittens. This is very efficient, just a put on the shoulders of the cat once a month and you will literally not see a pesky flea or tick on their coat any longer. Protect your animal, and save yourself the time and money from a vet visit.
