Article in English: Hairballs are common in cats and are a result of your cat’s normal grooming habits.  When cats groom themselves, they ingest hair, which can irritate the stomach, inducing vomiting. By brushing your cat, you minimize the amount of hair it might ingest, preventing your cat from vomiting a hairball.  Brush  your cat daily. Brush both long and short haired cats. Use a comb to remove knots. Use a rubber brush to remove loose hairs. There are several kinds of cat food on the market designed to minimize hairballs. Try to choose a dry food formula which has high fiber content. Fiber helps hair to pass through the digestive system. If your cat frequently has hairballs, you might consider keeping a cat lubricant paste on hand. These lubricants are designed to help cats pass hairballs.  A number of different products exist, such as Lax-a-paste or Katalax. Many are made of inert liquid paraffin and are often given a flavor so your cat will lick it. Apply about one inch to the cat's paw, twice a day for two to three days, so that it licks it off. The paste coats the hairball and either helps it pass out in the feces. Some cats eat quickly and in doing so swallow a lot of air with its food.  This can cause its stomach to become irritated and it will vomit shortly after eating.  Stop this behavior with a few simple actions:  Divide its food in a muffin tray to make smaller portions and slow down its eating. There are already many devices for purchase that are designed to dispense food slowly.
