This product was terrible! One if my cats was foaming at the mouth and lethargic within 20 minutes of this product touching her skin!! Had to bathe her immediiatly to wash it off!! Buyer beware and pay close attention to your cats if you use this!
Frontline used to work really well on my kitties but this last couple of years the product seems to have gone down hill a bit... It could just be that I got a bad batch but I doubt it. Will update if things change
