Yes, cats can get hiccups. Hiccups in cats are involuntary spasms of the diaphragm, similar to humans, and are more common in kittens but can occur at any age. Common causes include eating too quickly, swallowing air, overeating, and hairballs. While occasional hiccups are usually harmless, prolonged or frequent hiccups could indicate more serious underlying problems such as asthma, heart disease, or ingestion of foreign objects, and warrant a veterinary checkup.
