What to do now

Cats can decline quickly when appetite drops, especially with vomiting, hiding, pain, or lethargy.

Monitor

  • Track the last normal meal and whether favorite foods are refused.
  • Watch water intake, vomiting, stool, urination, hiding, and energy.
  • Note stress changes, medications, dental signs, and possible toxin exposure.

Call a vet

  • Call today if your cat is not eating normally.
  • Call sooner for kittens, seniors, overweight cats, or cats with chronic disease.
  • Ask whether your cat needs same-day evaluation.

Emergency now

  • Use emergency care if appetite loss comes with weakness, collapse, trouble breathing, or repeated vomiting.
  • Use emergency care after possible toxin or string exposure.
  • Do not wait if your cat seems painful or hard to wake.

Red flags

  • No appetite with hiding or lethargy
  • Repeated vomiting
  • Trouble breathing or collapse
  • Possible string, plant, medication, or toxin exposure

Possible causes

These are non-diagnostic examples to help frame a veterinary conversation.

What to track before the vet

  • When signs started and whether they are getting worse
  • Eating, drinking, litter box changes, and energy today
  • Any vomiting, diarrhea, blood, collapse, or breathing changes
  • Recent stressors, diet changes, medications, or possible toxin exposure

When to get care

Use the intake flow if you want a structured way to organize the symptom details before you contact a professional. Seek prompt care when signs are severe, worsening, repeated, or paired with breathing trouble, collapse, pale gums, pain, or inability to keep water down.
