Will too much Frontline flea medicine hurt my cats?

Hi,
I gave my cats frontline flea medicine (the kind where you use a syringe and squirt the medicine on the back of the neck) on April 7th and I noticed today that they still have fleas, and I gave them another dose today(April 11th). I know I was suppose to wait a month but they still have fleas. Will it hurt them? The dosage that I gave them was .5 ml Please let me know if this will hurt them, and do I need to call the vet? Also if they still have fleas after this what should I use next? Thanks.

often the shop bourght flea treatments don't work as they don't contain a serios enough drug to eradicate the fleas (fleas are tough little critters), As long as your cats are not showing any ill effects from the double dose they should be ok. Check with the padket, sometimes it will say what to do in case of giving too much, if it doesn't then it's probably because it won't harm them.

I would suggest not giving thme any more, waiting afew weeks, keep grooming them especailly around the neck area and then if they still have fleas take them to the vets to be prescibed the real flea medication. thats what we did with our cat as we found the shop ones of no use either.
