✓ Watch the whole pattern
✓ Contact a vet sooner for kittens, seniors or cats with another illness.
✓ Record timing, frequency and related changes
A symptom is information, not a diagnosis. One mild episode may pass, but blood, pain, dehydration or persistence matters. When in doubt, a veterinary professional can triage the situation using your cat's age, history and current signs.
