Is my kitten drooling from flea spray? When should I call the vet?

Hi, I have a 4-6 month old kitten, and all of a sudden, it has been drooling an excessive foamy substance along with water for the past hour on and off. I was wondering, could it be the fact that I gave her flea spray an hour ago? Or was it something else that could have caused it, and is this type of problem serious?

Flea spray can cause a reaction such as you're describing, especially if she ingests some of it, which cats will often do while grooming. Hopefully it's just a reaction to the taste of the spray, and will pass quickly. If it continues for more than a couple of hours, or if she becomes lethargy or unsteady, take her in to the vet immediately, as she could have a more serious reaction to the medication. Also, if the spray contains pyrethrin, have her seen immediately, as this is highly toxic to cats.

Advantage spray shouldn’t be toxic if a typical dose was ingested by your cat but it does sound like she doesn’t like the taste. It might be best to wash the product off with dish soap, but she’ll need another product for flea prevention. You could ask your vet for a prescription topical, or something like Frontline (fipronil only) would be safe to use after the Advantage spray. Be sure to apply it to the back of her neck where she can’t groom.
