FAQ
Is mouth ulcers / red oral tissue in cats serious?
It depends on the combination of symptoms, how long it has lasted, and your pet's energy and appetite.Note that it can appear in problems that need prompt care, such as Stomatitis / severe periodontal disease. Enter the full symptom combination in our symptom checker for a more specific urgency assessment.
Can I monitor at home first? What should I watch?
If energy and appetite are normal with no other signs, 24-48 hours of monitoring is reasonable. Keep notes on frequency, duration, appetite, water intake, energy and what the stool/urine looks like — vets find this very useful.
What should I prepare before the clinic?
Note when the symptom started and how it changed; bring packaging or residue if ingestion is suspected; bring vaccination and deworming records; and if possible take a video (odd gait, cough sound) — clearer than describing.
