Why is my cat drooling constantly, even when sleeping, after tuna?

Updated On September 23rd, 2025

Pet's info: Cat | American Shorthair | Female | unspayed

My cat started drooling (especially when sleeping) and vomiting after she has eaten tuna for a week now. Although the vomiting has stopped, the drooling is still persistent after replacing the tuna with cat canned wet. The front of her mouth is always soaked.

Hi there and thank you for using pet coach to address your concern. I would recommend having a veterinarian examine her so that the most appropriate diagnostic and treatment recommendations can be made. She could be dealing with severe dental disease or other disease in her mouth. The drooling could also be a sign of nausea so I would also recommend having her blood tested to see if there are any systemic changes that could be causing the drooling / nausea. You may even consider adding in a probiotic such as Purina fortiflora which can be found online quite easily or at your local pet store. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns.
