Query: great fle killer:)

i have tried alot of products, this is the only one with in a hr the fles were starting die, my cat was laying on the kitchen floor and she got up and you could see all these little black dots on the floor which were fleas!!!! all dead she is sooo happy, eating better and not sleeping as much, the only thing i wish that this product did was repale them, when it gets close to the end on the 30 days they start to hop back on and have lunch, thats the only problem, but it does a great job at killing them and keeping them dead for about 25 days i called my vet and she said reapplying 5 days early was ok to do not any sooner than that, so i would recomend do that to keep ur kitty flea free!!!!! hope you guys like it, it works awsome:) everyone have a great day!!
