Why Does My Cat Vomit Then Drink Heavily?

๐Ÿ“ Summary

Heavy drinking after vomiting is the cat replacing lost fluid; common triggers are acute gastritis, kidney trouble (diabetes or failure), or food poisoning. Withhold food briefly and see a vet if it continues.

1 Acute Gastritis

Acute gastritis shows as frequent vomiting; the cat drinks heavily to replace lost fluid and avoid dehydration, often with diarrhea. Withhold food and water, give a probiotic and an antibiotic powder, and for severe cases an anti-nausea tablet; pair diarrhea with an anti-diarrhea tablet that also protects the gut. If vomiting persists next day, see a vet.

2 Kidney Problems

Diabetes or kidney failure brings wasting and dullness; see a vet. Kidney disease is irreversible, managed only with medication and diet to slow decline; a kidney-support supplement can aid detox.

3 Food Poisoning

Many poisonings cause vomiting and heavy drinking; common ones are salt poisoning (salted fish or meat: restlessness, drinking, vomiting, diarrhea, drooling) and spoiled food (mold: dullness, appetite loss, vomiting, thirst, abdominal pain). The dose decides danger; severe cases can die within 12 hours, so seek urgent washing and fluids.
