Cat Emergency Signs: When to Go to the Emergency Vet Now
Short answer
If your cat has trouble breathing, open-mouth breathing, blue or very pale gums, collapse, seizure activity, suspected poisoning, inability to urinate, severe trauma, heatstroke signs, repeated vomiting with weakness, bloody diarrhea with weakness, or cannot stand, call an emergency veterinarian and go now. VCA lists breathing difficulty, trauma, poisoning, vomiting, diarrhea, heatstroke, and urinary problems among cat emergencies; ASPCA emergency-care guidance tells owners to contact a veterinarian immediately for serious illness or injury. Do not wait for an online answer, supplement, or home remedy.
