What is the difference between vomiting, retching, and coughing?

Things you shouldn't do yourself
Do not induce vomiting if you suspect poison or a foreign substance. Unless directed by a veterinarian, Cornell warns that some toxins do more harm the longer they are reversed. And cats that are lethargic or swallow abnormally are at risk of choking.
Do not give people medicine, anti-emetics, antacids, or pain relievers. Do not give water or food to a cat that is severely vomiting, lethargic, has difficulty breathing, or cannot swallow. And do not pull any string or thread that is sticking out of the mouth or anus. because it may cut the intestines Go see a veterinarian.
Hairballs are not a description every time.
Hairballs can sometimes be a mild cause, but Cornell says frequent vomiting is cause for concern. And blockages from hairballs or foreign objects can be life-threatening. If you frequently vomit hairballs, eat less, become constipated, lethargic, or vomit repeatedly without hairballs. See a veterinarian
You should not conclude that a hairball is normal just by looking at the presence of hair. This is because cats swallow fur naturally and the fur can get stuck in the vomit from other causes.
