Applied advantage flea meds on 4 month old kittens. They seem lethargic. Did we overdose?

Question

We have 2 cats and 2 kittens, all got same dose of Advantage flea drops. Did as instructed and separated them for 24 hours. Worried we might have overdosed the kittens. Package says 9lbs. and under.

Answer 1

They should be fine. You didn't overdose.

Just remember that flea products are a poison, even if they are deemed safe, so they can affect the overall health of the pet for a day or two until they wear down a bit.

If the kittens don't perk up in 72 hours, see the vet for sure.  

Answer 2

You should definitely call a vet and/or Advantage to ask them.  An adult dose of flea medicine is really a lot for a kitten that small, but the veterinary hospital I worked for exclusively sold frontline, so I don't know what side-effects advantage can have.  Better safe than sorry though, so call someone.

Answer 3

You might want to ask your vet.  My kitty always got lethargic for a couple of days after a flea treatment, but turns out she was allergic to it.  So now I just stick to the collars and she's a happy kitty.  But you'd have to ask your vet.

Answer 4

call the vet, better to be safe than sorry.  i hope that they are alright.

Answer 5

When it comes to dosing kittens for anything, you should always consult a vet or the vet tech before doing it.  You may have overdosed them, it depends on how old they are.  I would call the vet and explain what happened so if steps need to be taken, they will in a timely manner.  Diagnosing problems on the internet is just not a good thing, no one has all the information needed (cats blood pressure, heart rate, temp, what the eyes look like, size, breed....) there are too many variables.  Call your vet.
