Medications designed to kill off fleas on cats are made with toxins and insecticides. While they are not deadly for the cat, they can cause drooling and other symptoms if the cat licks off the medication.
Drooling
Drooling is a common symptom of a cat who has ingested flea medication, according to veterinarian Mike Richards from Vet Info.com.
Signs
If drooling is accompanied by other symptoms of poisoning, such as vomiting and lethargy, the cat needs veterinary attention. Otherwise it is a normal symptom and will resolve on its own.
Application
Many flea medications, such as Frontline, are designed to be placed between the cat's shoulders. This location makes it difficult for the cat lick the medication.
Warning
Flea medications designed for dogs that contain the insecticide permethrin is toxic and deadly for cats. Drooling is a symptom of permethrin poisoning.
Considerations
Flea medications should not be used on pregnant cats, old cats or kittens. If these cats are drooling after the use of flea medication, they need to see a veterinarian.
