We use this on both of our cats, monthly, to prevent fleas & ticks. It doesn't irritate our cats' skin or make them lethargic.

For my cat, it works just as good as Advantage and Frontline and it's a bit cheaper

I like the product as I've used it before, but the packaging was a problem- luckily the medication itself was intact but the outer box was sent in a padded envelop and it was crushed in transit

I use this preventively. So far there's NO signs at all of flea activity.

It worked very well for us. You can't beat the price either.

Works very well. We have 7 cats so we need something that works but isn't as expensive as some of the name brands out there. This is a great product. The packaging is great. The only thing I would say against it is that the individual doses are a bit hard to open but the medicine is so good that I am willing to overlook that for the value.
