"It is understandable to feel concerned when you find something unexpected in your drink, but I want to reassure you immediately that this is not life-threatening. The substance you saw at the bottom of the coffee glass is most likely undissolved milk solids, coffee creamer, or a harmless byproduct of the brewing process. Even in the highly unlikely event that it was cat saliva, rabies and other significant feline-borne diseases cannot be transmitted by ingestion (swallowing). Stomach acid is extremely effective at neutralizing such viruses before they can cause infection
Next Steps
Anxiety Management: "The 'panic' you are feeling is a physical reaction to fear. Practice deep breathing (4 seconds in, 4 seconds out) for five minutes to lower your heart rate and allow your rational mind to take over."
Observation: "There is no medical 'test' needed for swallowing a suspicious substance in a drink if you have no symptoms. Simply observe your health for the next 24 hours. You will likely find that you feel perfectly fine."
Kitchen Hygiene: "To prevent future scares, ensure that all glassware is rinsed thoroughly before use, especially in a household with pets, to remove any dust or residue."
