This is a widely debated topic both online and in the medical world. It would seem that while dogs seem to burp quiet often, cats seldom seem to… If at all. If you are wondering if a cat burps or not, or is even capable of burping, science will show you your answer.
To better understand if a cat can burp or not, we have to see why we burp in the first place. The most common reason is because we breathe through our mouth in general, while eating, or when talking. Some people do a mix of breathing through the nose and the mouth. People who talk more or breathe through the mouth more take in more gasses such as oxygen and nitrogen. This directly affects the stomach when too much is taken in. It will either be expelled back through the mouth or it will carry down through the intestines. Another thing that causes burping is fizzy drinks. People who seldom drink soda will notice this a lot more than others who drink it on a regular basis. Another reason for burping (and farting) is the bacteria in the stomach and intestines. When they release gas, it builds up and it forced out again through the mouth or the rear! Gross right?
So knowing the above, it would make sense why dogs burp. They breathe a lot through their mouth and are more likely to swallow air. But what about cats? Now this is what pretty much reassured me that cats don’t burp… They very rarely breathe through their mouths. This only happens when they are yawning, very stressed, or very warm. They will also use their mouth to taste what they are smelling but they aren’t actually breathing when they do this. If gasses do come up through the mouth, we are likely to never hear it, which means they do not burp. Burping is considered the noise of the gas being expelled through the mouth.
