My cat first vomited up its kibble, then with no food left vomited yellow fluid

For a cat vomiting yellow fluid, do not give over-the-counter human cimetidine tablets, a human drug for excess stomach acid, gastric pain, or ulcers. First, giving any drug without knowing the cause is unadvised, and a human drug can cause side effects because cats’ physiology and metabolism differ from humans, with different dosing and methods.

If your cat vomits yellow fluid, first withhold food and water and take it to a vet for diagnosis and treatment based on its condition. If a vet is truly unavailable, choose a pet-formulated cimetidine such as Puxiding, follow the instructions and the cat’s condition, and observe its response closely afterward.
