The drooling could be a result of nausea or irritation in the oral cavity. We can also see drooling with some toxins (for example organophosphate toxicity). I am not sure what kind of poisoned fly he ingested, if it was poisoned with a chemical or the fly itself made him sick (here in the US we wouldn't see a toxicity from ingesting a fly but I am not sure if there are different types of insects in your region). I would call your vet to let them know that the kitty is still drooling. They may say it is a normal side effect or they may want to further examine his mouth or give him medicine for nausea.

    Poor Twichy! If there were household cleaners in the bathtub, that could be upsetting his stomach and causing the drooling. Drooling is a sign of nausea in cats. I recommend withholding food tonight, then in the morning feeding him a bland diet of boiled white meat chicken (no bones) in small amounts several times a day. Do this for a couple of days, then slowly add back in his normal diet. Should the drooling continue or get worse, he starts vomiting, or he shows other signs of toxicity which include tremors, seizures, anorexia, and/or lethargy, rush him into a vet immediately. Good luck, I hope this helps!

    The drooling may be due to nausea, periodontal disease, trauma or toxicity. If he is behaving normally otherwise, it is probably not trauma or toxicity. You can try withholding food for 12-24 hours. Allow small amounts of water or unflavored PediaLyte. Resume feeding a bland diet in small, frequent amounts. Begin with 1 teaspoon of food every hour and gradually increase the amount if there is no vomiting. Feed bland until symptoms resolve then transition slowly to the regular diet. Symptoms that should be addressed by your veterinarian include lethargy, persistent vomiting or diarrhea, loss of appetite or abdominal pain.
