Yes, I use it along with this one: TickLess Pet Ultrasonic Tick & Flea Repellent Device Pendant for Dogs & Cats (this one lasts for 1 year and can't go in water). So they have 2 tags on.Thanks for the responses. I use neem oil too and so far have had good results but it's also been pretty cold here. Come spring I will probably need to add something. I saw this tag but it seems too good to be true! Anyone try it?
