It's concerning to see your cat drooling after flea treatment. My small female kitty, Alice, did not tolerate topical treatments well at all. I just knew her little body was panicking, as she hid under a bed and held herself stiff as a board, with huge eyes, for many hours. We didn't repeat that treatment.
Cats are like people. They are each unique, with different temperaments and different bodies. Just as we humans vary, so do they. One human may tolerate a medicine, another may have a side effect.
The most common type of flea treatments are pyrethrum-based. The main ingredient will be listed as pyrethrum, pyrethroid, or permethrin. Cats are especially sensitive to pyrethroids.
Also, cats are particularly sensitive to these pesticides because they have less effective metabolic pathways, and because of their grooming instincts.
According to MedVet, drooling and excessive salivation are symptoms of flea control product toxicity. Toxicity can occur from one to twelve hours after application, and vary from pet to pet.
Other symptoms include muscle tremors, diarrhea, vomiting, difficulty breathing, small pupils, weakness or falling over.
Flea product toxicity can be treated, and your cat can recover. But you must call your vet immediately. Depending on the severity of reaction, other symptoms, and type of toxicity, intravenous liquids could be needed.
They may also prescribe medication to lessen symptoms and help your cat eliminate the toxins from his body.
It may be recommended that you gently bathe your cat to remove any residue you can, using a gentle soap such as dawn liquid detergent, and make sure your cat dries fully, as she will be susceptible to chilling.
Cats with lower body temperature are at a higher risk of showing signs of toxic poisoning.
Excessive salivation, or cat drooling after flea treatment, is considered a mild reaction. It is the most common reaction along with muscle tremors (a moderate to serious reaction). Other symptoms in the mild category include paw flicking, ear twitching, mild depression, vomiting and diarrhea.
Reactions such as paw flicking, ear twitching and cat drooling after treatment are often mild and resolve. So it's possible that nothing more will come of it and kitty will be fine after calling your vet and monitoring. If symptoms progress to muscle tremors, she will need immediate care for stabilization.
