Why is my cat shaking? Shaking can happen from cold, fear, pain, nausea, fever, toxin exposure, or neurologic problems. Sudden shaking with weakness, vomiting, collapse, or confusion should be checked by a veterinarian.
Why is my cat breathing fast? Fast breathing can be caused by stress, heat, pain, fever, heart disease, lung disease, or breathing distress. Fast breathing at rest, open-mouth breathing, pale gums, or weakness should be treated as urgent.
Why is my cat not eating? Not eating can be caused by nausea, pain, dental disease, stress, fever, or a more serious illness. Appetite loss is more concerning when it lasts more than a day or happens with hiding, vomiting, diarrhea, lethargy, or fast breathing.
Why does my cat have diarrhea? Diarrhea can come from diet change, stress, parasites, infection, intolerance, or intestinal inflammation. Watery, bloody, repeated, or worsening diarrhea needs closer monitoring and may require veterinary care.
Why is my cat vomiting? Vomiting can happen from stomach irritation, diet change, hairballs, infection, toxin exposure, or obstruction. Repeated vomiting, vomiting with weakness, or vomiting with appetite loss should be treated as a veterinary concern.
