FRONTLINE Plus for Cats (19120-V)
I've used it for years and it works well. Beware buying from unknown websites as there are people that will sell a knockoff product.
I use this regularly. It works well for me.
I ran an AKC kennel in Al and had Yorkies, Shih Tzu's & Cocker Spaniels. Used on all my dogs ( pregnant & newborn) and NEVER had any problem what-so-ever. I highly recommend it.
It WORKS GREAT FOR ALL MY PETS
I had been using Advantage for years, but last year, it didn't have any effect. All my critters had fleas. I found a natural supplement that had really good results, but none, so I went to Frontline. Within 2 days, everyone was flea free, and it lasts a bit longer than a month. Also, I have an iguana that got mites that I fought for months with other products, I sprayed her one time and she was mite free-that was 4 years ago and is still mite-free.
Lost Effectiveness in My Area
I live in north central Texas. I used Frontline / Frontline Plus religiously for years and could not have been happier. Unfortunately, three years ago it totally quit killing fleas on my dogs. I'm sure they had developed resistance as they were covered far worse than I had ever seen. It never had been effective on ticks, so I (reluctantly) switched to Advantix. Occasionally, I will use Comfortis just for fleas if it is not tick season.
