My Cat Keeps Hiccuping. It is a common physiological phenomenon caused by spasmodic contraction of the diaphragm. Most of the time, hiccups end as suddenly as they begin.
Licking and swallowing may also indicate mouth issues, such as a foreign object stuck there, or teeth or periodontal problems. If the air isn't expelled through burping, it may result in flatulence 15 to 35 minutes after. If you feel this may be the case for your cat, ensure to observe them while eating to see if they are eating normally.
