I used to purchase drops until the vet explained my "discount name-brand flea meds" purchased online weren't regulated by anyone and could potentially harm or kill my cats so I immediately looked for an alternate solution. I'm thankful there is a non-toxic solution for my fur babies.
The cats have been flea free for years anyway but I got this because I'm moving and they will be able to roam outdoors again, the move hasn't happened quite yet but since they don't mind it, (I add to their food each morning with or without wet food they still eat-the garlic smell doesn't affect them) so I will continue to purchase to maintain the critter free status in our new house as well.
It says 1/2 a scoop and since it's difficult to gauge half in such a small scoop, i purchased an extra 1/8 teaspoon as that is the dose and use that to dose instead of included scoop. I will use this on all my pets as long as they go outdoors and will gladly recommend this product to my friends and family. THANX AGAIN NULIFE!!
