Under normal circumstances, a cat's hiccups usually stop within a day at most, but if the cat hiccups often and very frequently, you should consider whether the cat has eaten too much or there is foreign matter in the throat. In addition, it is worth noting that if the cat’s hiccups persist for several days, it may be a brain tumor or a problem with the nervous system. It is best to go to the hospital to check the cat’s body.

What to do if your cat hiccups frequently:

1. Make sure there is enough food and water. Give your cat plenty of food and water and a quiet space, and don't try to force your cat to eat or drink. If your cat likes to drink running water, try using a drinking fountain.

2. Change the cat’s habit of overeating. You can place the food in a higher place where the cat cannot easily access it, or use a feeder to slow down the eating speed.

3. Solve the hair ball problem. You can try using cat grass and hair removal cream to stimulate gastrointestinal motility and help cats expel hair balls.

4. See a doctor. If your cat hiccups frequently but can't find the cause, or if the hiccups last for more than a day, take her to the doctor.
