Cats will lose a lot of hair during the shedding season. This also causes cats to swallow a certain amount of hair into their intestines and stomach during grooming. Since the pancreatic digestive enzymes in the body cannot completely break it down, the hair balls will be expelled from the body through self-induced vomiting. Almost all cats vomit hair balls. The longer the hair, the more they love to lick it, and the higher the frequency of hair vomiting.

However, cats often vomiting hair balls is not a natural phenomenon, but is more like an early symptom of emergency enteritis. The normal gastric emptying time of cats is between 15 minutes and 2 hours. If the gastrointestinal motility is normal, all the cat hair swallowed during this period should be excreted rather than accumulated or even turned into hair balls.

Note: Any cat that vomits hair balls more than twice a month is very likely to suffer from chronic small intestinal disease; short-haired cats (such as Siamese cats, Sphynx cats, etc.) will have the same situation if they vomit more than once every two months. .

1. Complications caused by hair balls

· Hairball syndrome: Continuous vomiting and retching without producing hairballs, leading to symptoms such as loss of appetite, lethargy, constipation and diarrhea.

· Intestinal obstruction: an advanced version of hairball disease. The hairball blocks the intestines and stomach. The cat will vomit whatever he eats, and then becomes dehydrated and suffers from internal organ failure. Immediate surgery is required for treatment.

Note: If the above symptoms occur, it is recommended to rush to the nearest hospital for diagnosis and treatment immediately.

　2. Basic coping methods

· Regular grooming: The more you comb the fallen hair, the more it will reduce the amount of hair in the cat's belly and make it easier to expel.

· Distraction: If your cat is compulsive about grooming, try distracting him with toys or other activities.

· Dietary aids: Eat specialized cat food, cat grass (feed at least the minimum dose every day) and hair-reducing cream (overfeeding can easily cause cats to have soft stools), etc. to promote gastrointestinal motility, egg yolks (1-2 per week) Egg yolk, 2-3 for long-haired cats, effective within one month) can also reduce the risk of cat hair retention.

Hairballs in cats are just one of the more common vomiting symptoms. Seemingly harmless vomiting should no longer be ignored. In particular, long-term habitual vomiting is abnormal, but many parents take these vomitings for granted, and it is too late when they discover that their cats are obviously unwell.

Basic treatment methods

· Vomiting just after eating: It may be that the cat is allergic to food. You can feed it a prescription food with a hypoallergenic formula.

Before taking your cat to the hospital, it is recommended to pay close attention to (or take photos of) the appearance (color/odor/abnormality) and what of the vomitus.When did the vomiting begin, how many times, the last time, the medicines taken, changes in the cat’s living environment, changes in diet, abnormal behavior and diarrhea (it is best to bring samples), etc. Cats are good at camouflaging, and only the most subtle things are noticed Only changes can help doctors provide more accurate treatment.
