After a cat is poisoned by aspirin, the pet owner should first induce vomiting and gastric lavage, and then give the cat some milk or egg white to protect the cat’s gastrointestinal mucosa. After that, he was immediately taken to the hospital for infusion treatment to alkalize the urine and relieve acidosis in the body. If the cat vomits and draws blood, hemostatic drugs need to be injected intravenously. In severe cases, hemostatic drugs can be injected intramuscularly twice a day.
