What to do now
A single hairball-like event is different from repeated vomiting, appetite loss, or lethargy.
Monitor
- Count episodes and note whether food, bile, foam, or hair is present.
- Track appetite, water intake, energy, and litter box changes.
- Keep food, plant, string, medication, and toxin exposure details ready.
Call a vet
- Call today for repeated vomiting, appetite loss, or vomiting with diarrhea.
- Call sooner for kittens, seniors, or cats with kidney, endocrine, or chronic GI disease.
- Ask whether your cat should be seen before offering food changes.
Emergency now
- Use emergency care for repeated vomiting with weakness, collapse, pain, or blood.
- Use emergency care if your cat cannot keep water down or seems hard to wake.
- Treat string, plant, medication, or toxin exposure as urgent.
Red flags
- Repeated vomiting
- Blood or coffee-ground material
- Lethargy or hiding with appetite loss
- Possible string, plant, medication, or toxin exposure
Possible causes
These are non-diagnostic examples to help frame a veterinary conversation.

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.
