Nitenpyram is meant for short-term flea control for flea infestations. It's not meant to be used as a monthly preventative since its effectiveness only lasts for 24-48 hours. If you're looking for long-term flea control, you may want to look into Revolution for your kitty, which also covers heartworms and ear mites, as well as one type of tick

As far as your kitty's reaction to it, it very well may be from the fleas reacting to the Nitenpyram and moving around. If its a heavy flea load, even moreso.
Well I have read all that information before but nowhere do I see what the buggers are doing to torment my cat for like I said up to an hour after ingesting the product. I have found that it will do the job just as well as Advantage giving it to him once a week but it hurts me to see his frantic digging at something the fleas are doing. Don't make sense that a dying flea would bite with his last breath.
