He has fleas.Can I give my cat a double dose of Spot on flea repellent?
No, as overdosing a cat can be fatal. Always get flea treatment from a vet and follow the instructions carefully.Can I give my cat a double dose of Spot on flea repellent?
No never double dose, it could be harmful to the kitten.





One dose is enough, you should allow 48 hrs for the treatment to start working and taking effect.





Note if the spot on treatment you are using is over-the-counter it is unlikely to be very effective. Use frontiline or stronghold.





It is important to buy a spray to treat the environment too, as fleas lay eggs in the cats bedding, in your carpets etc and can reinfest your cat with fleas again. Get the spray from a vet/animal shelter store.
Only if you want to kill him.





The flea drops are strong pesticides, and the dose is regulated by the size/weight of the cat (see the box instructions). If you double dose, the cat has a toxic overdose that is going to start destroying his liver, killing him. These are intensly strong pesticides and having it on your skin will do the same to you.





Fleas don't ALL die in two days. The ones that are in the environment and haven't bitten the cat won't be poisoned till they get back on him, so what looks like an infestation not being touched actually isn't. Remember that flea eggs will be hatching as well, for up to 3 months, making it look like fleas haven't died at all. But the dose is working and will continue to work for a good 30 days. As new ones jump on the cat they die, the dead ones all fall off, so you're going to be seeing things around till the last of them dies.
No, don't. Mostly because it will be pointless but also, if it's a spot-on treatment from a pet store you will be risking your cat's life.





Never use pet store flea treatments, they are often dangerous and usually useless (with the exception of Frontline).





If you are already using a proper flea treatment from a vets, like Frontline or Revolution etc there is no need for a second treatment within a month. If you are still seeing fleas 48 hours after applying the stuff (presuming you got it on correctly i.e. the skin) it means you need to spray your house - this is where most of the fleas are living.





If you have used a pet store flea treatment and are still seeing fleas after 48 hours it's because, as I've said the stuff won't work - and also you probably need to spray your house!





If you've used a pet store flea treatment, you need to now get some proper stuff from a vets. Ask their advice about when you can apply it; we recommend waiting a week after applying a pet store treatment, in case it interferes with the action of the proper stuff.

No. Most over the counter flea treatments like Spot On are ineffective, and many are downright toxic. See your vet and get a prescription topical treatment like Advantage, Frontline or Revolution. They work and they won't kill your cat like some of the over the counter ones can. If you've already applied Spot On, let your vet know when you applied it so s/he can advise you when it's safe to put the other treatment on him. You'll also need to treat your home if he's indoors. If you don't, you'll end up with an infestation. Talk to your vet about what product(s) will be safe to use in the home. Here's more information about over the counter flea treatments:

No, my vet said some cats have died because they're given the wrong dosage of flea and tick medicine.
