Do cats burp, and is it normal?

Yes, cats can burp, though it is far less frequent and less noisy than in people, so most owners never notice it. An occasional burp after eating quickly or swallowing air is nothing to worry about, the feline equivalent of a person gulping a meal. A pattern of frequent burping, especially paired with drooling, lip-smacking or reluctance to finish a meal, is a different picture and points toward nausea or reflux rather than normal digestion. The frequency and what comes with it is what separates the two.

When to call a vet: Frequent burping alongside drooling or reduced appetite is worth a vet visit to rule out reflux or nausea.
