Chronic Vomiting in Cats: A Vet’s 2025 Guide to Diagnosis, Treatment & Home Care 🐱🤢
By Dr Duncan Houston, BVSc
🔍 What Is Chronic Vomiting?
Chronic vomiting is defined as vomiting that persists intermittently or continuously for more than three weeks and should always be evaluated by a veterinarian—it can signal serious illness or require surgical intervention :contentReference[oaicite:3]{index=3}.
⚠️ Why Cats Vomit: Causes Overview
- Gastrointestinal: IBD, food allergies, motility disorders, ulcers, neoplasia (e.g., lymphoma), foreign bodies :contentReference[oaicite:4]{index=4}.
- Systemic diseases: Kidney disease, hyperthyroidism, pancreatitis, liver disorders, endocrine issues :contentReference[oaicite:5]{index=5}.
- Parasites & infections: Giardia, roundworms, bacterial overgrowth, viral infections :contentReference[oaicite:6]{index=6}.
- Toxic ingestion: Plants, chemicals, human medications :contentReference[oaicite:7]{index=7}.
- Hairballs & diet issues: Fast eating, hairball accumulation, sudden food changes :contentReference[oaicite:8]{index=8}.
🚩 Recognizing Warning Signs
- Vomiting with blood (hematemesis), bile, or complex matter :contentReference[oaicite:9]{index=9}
- Accompanying symptoms: lethargy, weight loss, decreased appetite, diarrhea, dehydration :contentReference[oaicite:10]{index=10}.
- Behavioral changes, abdominal pain, fever, foul breath :contentReference[oaicite:11]{index=11}.
- Frequency: vomiting more than once a week warrants veterinary attention :contentReference[oaicite:12]{index=12}.
🔬 Veterinary Diagnostic Roadmap
- History & exam: Review diet, timing, frequency, environment; physical palpation for masses or pain :contentReference[oaicite:13]{index=13}.
- Fecal tests: Floatation, direct smear, PCR/ELISA for parasites and Giardia :contentReference[oaicite:14]{index=14}.
- Blood & biochemistry: CBC, chemistry panel (kidney, liver), thyroid, pancreatic enzymes :contentReference[oaicite:15]{index=15}.
- Imaging: X‑rays or ultrasound for foreign bodies, masses, structural GI issues :contentReference[oaicite:16]{index=16}.
- Endoscopy/biopsy: Shows mucosal disease; essential for diagnosing IBD, neoplasia :contentReference[oaicite:17]{index=17}.
- Additional tests: Viral tests, toxic screenings; differentiate vomiting from regurgitation :contentReference[oaicite:18]{index=18}.
🛠️ Treatment & Medical Management
A. Treat Underlying Cause
- Parasites: Metronidazole, fenbendazole, ronidazole :contentReference[oaicite:19]{index=19}.
- IBD & food sensitivities: Hypoallergenic/hydrolyzed diet + immunosuppressives (steroids, cyclosporine) :contentReference[oaicite:20]{index=20}.
- Systemic disease management: Treat CKD, liver disease, hyperthyroidism, pancreatitis appropriately :contentReference[oaicite:21]{index=21}.
- Neoplasia: Surgical removal, chemotherapy, palliative care—especially in GI lymphoma :contentReference[oaicite:22]{index=22}.
B. Supportive & Symptomatic Care
- Fluids: IV or SC to prevent dehydration and restore electrolytes :contentReference[oaicite:23]{index=23}.
- Antiemetics: Maropitant (Cerenia) relieves nausea—effective for repeated vomiting :contentReference[oaicite:24]{index=24}.
- Bland diet: Easily digested meals after vomiting subsides :contentReference[oaicite:25]{index=25}.
- Probiotics: Forti-Flora, Proviable to restore gut flora and reduce GI upset :contentReference[oaicite:26]{index=26}.
- Motility modifiers: As needed—but always after ruling out obstruction/infection :contentReference[oaicite:27]{index=27}.
🏡 Home Care & Monitoring
- Feed small, frequent meals; gradual diet transitions :contentReference[oaicite:28]{index=28}.
- Monitor vomiting frequency, stool, appetite, water intake, and behavior.
- Use **Ask A Vet** app for vet guidance and reminders.
- Encourage hydration: water fountains, wet food, easy clean bowls.
- Brush coat routinely to reduce hairball formation :contentReference[oaicite:29]{index=29}.
- Provide comfy, stress-free environment with calming **Woopf** & **Purrz** products.
📅 Prognosis & Follow-Up
- Schedule rechecks every 4–12 weeks including exam, labs, imaging–based on condition severity :contentReference[oaicite:30]{index=30}.
- Response to treatment is critical: reversible causes may fully resolve; chronic diseases managed long-term.
- Severe GI diseases or systemic illness may need ongoing care; palliative comfort remains crucial.
